My thoughts, so far, on Windows 10 Mobile build 10512

So today Microsoft released build 10512 (and technically another branch) of Windows 10 Mobile for those on the Windows Insider program. Part of me wants to say finally released. However, that seems a bit presumptuous especially since the company just pushed out the largest desktop OS update in their history. I think I can cut them some slack for an OS not due to the fall.

Still, I can be a little anxious, and it has been what seems like a long time since build 10166 weeks ago.

Today's updates took a bit longer than usual for a few reasons, so let me explain what I am running this OS on (so far) this evening. Throughout I'll pepper the article with some screenshots from the new build.

Test Devices

  • Lumia Icon – Downgraded to Windows Phone 8.1, updated to build 10166 and then build 10512 since you cannot directly go to 10512 yet. I also then did a master reset because, why not at this point. I have 25 GB of free space out of 29.1 on a clean install.
  • Lumia 830 AT&T – This device was on an ancient build of Windows 10 Mobile, and it took a few 'upgrades' to get to 10512
  • Lumia 1520 AT&T – Unfortunately, this phone does not see the 10512 update despite already being on 10166. I have no idea why.

The good

  • Despite what seemed like the very long update and migrations, both phones are running quite well. Each had numerous app updates, including 38 for the Lumia Icon as a fresh out-of-box experience.
  • So far, the Lumia Icon does not run hot or even warm. I have no idea about battery life. Time will tell after regular usage.
  • Yes, this build is noticeably faster, or perhaps a better way to describe it is it is smoother. Animations are looking great, and apps like MSN News and MSN Weather feel much more like they are part of a completed OS.
  • There are numerous new Windows 10 wallpapers included with this build including the 'hero' lockscreen one from the desktop OS. Most have a blue overtone, so I'd like to see more diversity. However, hey, I get it, Windows 10 is themed blue.

  • I like the default Tile setup that includes the Office apps and all the major services like Xbox, Microsoft Edge, Cortana, Outlook Mail, and more. In fact, dare I say I feel like I can leave the majority of these as they are and not have to add too many more apps. There is even a folder with Alarms, Calculator, File Explorer, OneDrive, Excel and Get Started. It is a weird thing to have that many necessary apps and services all come from Microsoft. Of course, there's still no Snapchat (sorry, had to say it).
  • Speaking of Live Tiles, they are flipping like crazy, and I mean that in a good way. Nice to see much Live Tile action with the native apps. Also, the sizing of the icons for the Tiles seem much more proportional.
  • Over 2,000 fixes is nice
  • It was as odd but nice to load up Skype and not have to log in on the first run
  • Windows 10 Mobile 10512 feels as good on the Lumia 830 compared to the Lumia Icon
  • Despite no noteworthy changes Microsoft Edge is running quite well; the next Mobile build, however, should see some significant improvements for the browser

The bad

  • Lock screen information has a two-three second delay on it before the user info or PIN are visible
  • No hotspot support (see Microsoft's list of known issues for more)
  • Still some stutters on animation
  • Obviously, there are no new features, just lots of bug fixes and performance improvements. This absence is not new, but if you are looking for anything exciting or things move around, this is not your build
  • Wi-Fi still disconnects on occasion
  • Windows Store is slow and miserable to use
  • Quiet hours appear to be broken, or rather the Quick Action constantly blinks again

Initial thoughts

So far, I like build 10512, and that should be an obvious conclusion for anyone running it. After all, the point of these releases is for things to get better.

On the Lumia Icon, I went all out to make sure it is a clean install so eliminate any issues that may incur during the update process. Besides the lock screen delay, which is infuriating since it is the first thing you see, the OS feels quite ready for daily use. Mind you, you can unlock the lock screen without the information appearing, so it is not that bad just not intuitive.

I noticed the out-of-box experience was much more polished. Most of the tutorial screens have been updated for Windows 10 Mobile, including the generic welcome text. There are many nice touches, including the built-in apps and default Tile layout.

Sure, there are few under the hood refinements to be made and hopefully more third-party apps to come, but Windows 10 Mobile is following the same path as the desktop version. A few more builds and people should be very happy with they see.

Should you rollback to 8.1 first? Should you do a hard reset before or after the update? I have talked about these issues in the past, and I still stick with the idea that yes, doing a master reset at some point on Windows 10 Mobile "fixes" many issues. Do note that this takes some time, upwards of 60 to 90 minutes depending on your where you are starting from and how many apps you install. If you can, however, live with a clean OS and not do a restore, I still recommend that path if you are using this a daily phone.

We'll shoot a video tomorrow to show off the speed of the OS, but other than some polish, most of the changes are out of sight, making a less compelling video.

  • Cool!
  • As far as new features or anything, are we expecting more before final release? I was under the impression that no real new features will be added from here out
  • Was planning on installing the next build on my 1520, assuming it would be close to RTM. Guess I'll keep waiting. :(
  • I have it on my 1520
  • Same
  • I installed on my ATT 1520. So far so good, except I have an issue with Edge. After 3 builds now have the same problem with it recognizing clicks on web links. Oh my God, The Store has finally been fixed! Was able to update every app installed on my phone. No other major issues so far.
  • My 1520 runs almost flawlessly
  • I am an early adoptor, and have this running on a spare L735.​ Its still not good enough for my main phone yet. Close, but still too slow/laggy, still too many jarring bugs. It feels sloppy, in a way the Desktop Windows 10 builds did not during their last 3->4 months. (I used W10 on my main PC at work way before RTM) This would function, but its jaggyness is still too much to bear for me.
  • I would like to see what are basic features missing from 8.1 added.
  • Hey, they will be releasing new features next month. Didn't want talk early on some of the improvements that TH2 brings. This info is per Joe Belfiore
  • I think next built would be suitable for daily use.
  • Joe Belifiore said in a tweet a few weeks ago that right now the focus is gonna be stability, and then right before official release they're gonna add more features
  • What could possibly go wrong with adding new features right before release?  Oh, wait: a lot.
  • So far, almost everything that COULD go wrong with Windows Mobile, IS wrong with Windows mobile. It's a damn disaster.
  • It's a little more stable and fluid than the previous build but it still has ways to go.  there's still no SMS notification and there are no separate third party mail apps, at least they were dysfuctional in the last build.  I did a master reset and still Cortana is missing on my 1020. When you swipe left or right, or scroll up and dowm, pics and email look wobbly. 
  • Does anyone have problems with their screen not rotating? After upgrading to this build(10512) I noticed that I can't watch full screen video because the screen is not rotating. I also did a reset and rotation is not lock.
  • I underestimated this build. It's super smooth and well worth the upgrade. Although not having Movies&TV app sucks. I only used it for Youtube videos which are downloaded from the myTube app anyway so i can watch them there. Or VLC even.
  • I updated to 10512 and I am able to play videos that I have taken with camera in Photos app. So the video experience is not completely broken.
  • What phone do you have?  
  • Sample Song is the best tune ever.
  • It installed from 10 166 to 512 on 1520 beautifully, I agree less heat on processor but no different really seems smooth
  • Not able to Download from previous build. Downloading stuck at 0%. At last did hard reset but then it stuck at wheeling. Restart and again stuck at wheeling. Loop continued and finally have to role back to 8.1. Lumia 638 india
  • At first it didn't show up on my 1520, I had to visit my insider app again and choose fast ring, then it started downloading, but I got a couple of error messages, all I did each time I had an error was to restart the phone. The download % kept increasing until it completed and installed. I still don't have glance screen option on this new build though.
  • how did you roll back when it was stuck while installing ?
  • Same on my Lumiq 925!It keeps restarting,then spinning gears.But I have one more thing:after the spinning gears,I have the :-( face.Now I have to roll back to Windows Phone 8.1 using Windows Phone Recovery Tool or Lumia Software Recovery Tool.
  • I've installed Build 10512 on two separate Lumia 830's.  One has the Start Screen Bug and one does not.  If a phone has the start screen bug it is a lost cause and totally unuseable just as a test device...   The groove app is still incomplete, many universal app are still not in parity with their PC versions (Fitbit etc.).  There are some general twitches and glitches but it is a quantum leap from Build 10166.  Everyone needs to keep pushing for Windows 10 Mobile to move forward.  Without mobility, what exactly is the point of Windows 10?  Without mobility we could all be happy with Windows 7 as a purely desktop OS without Touch, Speech, Continuum, Modern/Metro, and the Windows Store.  Without mobility Windows 7 could continue on for another decade like XP and Microsoft would fade to irrelevance as emerging technologies pulled us away from our desktops over time.  Windows 10 is more than the desktop OS, it is a broad range of progressive building blocks enabling the Microsoft experience to be mobilized and current and future technologies to enable the experience.  Right now a premier mobility experience on Windows phones is the single most important turnaround Microsoft must accomplish.  They must put every available resource to task to accomplish it. It is the current building block to transition into the future.  Where would Apple be right now if the original iPod never transitioned from a non touch single purpose music player into fully functional touch based phones and tablets?  Microsoft was caught stagnating as mobility evolved at light speed.  Microsoft somehow adopted a philosophy that third party developers must come to them and provide them with content.  Hopefully all that has changed and we will now get a forwardly progressive innovative leadership philosophy that will bridge the lacking content chasm with engineering innovation and hard work to bridge the gap between service providers and bring the service content to enable premier Microsoft ecosystem experience.
  • Quality writing as ever!
  • Really... Daniels thoughts.. Lol. He ain't Mr. Rogers....
  • Ask Dan, he has always loved the smell of his own... Ha. Looks like still only can create one live folder still.
  • Lol.
  • Yes indeed...thanks Daniel R.!
  • I went directly from build 10166 to 10512 on my Lumia 1520. I used my works WiFi.
  • me too
  • Ditto, maybe make sure your insider app is up to date? Lol
  • I like it a lot. Did the upgrade from the previous TP and hard reset on my 1520. Definitely has daily river quality if you can deal with the known issues.
    The only thing that annoys me a bit is that I don't seem to be able to turn off glance. Seems to be quite a battery sucker, especially since double tab to wake us on as well.
  • I was hard resetting my 720 before upgrading to this build. And the thing is that it is not starting anymore! The screen with the wheels comes, and then it shows its proceeding, and the bar fills to say 25%, and the process stops and a sad smiley... :-( like this shows up. And the process starts again. Been three days since it is happening. What should I do?
  • Use WPRT to flash win8.1. Then upgrade to Build 10512
  • Same here tejas. Rollback to 8.1. I just did it today. Phone will not detect initially, select "my phone is not detected". Still not detected then soft reset while phone still connected to PC. Download software and install
  • To fix the blinking quiet hours button, go to cortana>notebook>quiet hours.
  • That doesn't seem to fix it, at least not for me. I can go in and turn it on and off all I want, but the shortcut continually blinks. Granted, quiet hours themselves work, just not the shortcut to turn them on and off.
  • I like it , but no new features is extremely dissappointing. Look at iOS 9 alone, and search for 50 hidden featrues. So many refined polishes and touches, and what are we left with? Nothing. Literally just design changes. This is not good for Windows 10 Mobile. I love the animations, I love the UI style, but I hate the lack of the integrated Skype/Messaging app, especially when it was promised to be able to do SMS on desktop and have it sync with W10M I wish Microsoft moved faster with the phone builds. I want to be able to access the root of the phone and use it like a USB (like Android). I want to be able to show off cool new features to my friends. Windows 10 Mobile must be convincing for anyone to switch, and for current users to stay on Windows for phones. It really doesn't matter if people like Windows 10, that really won't increase the marketshare of Windows phones. There are tons of new features in Android M and many new refinements to iOS 9 (including those 100 or so hidden ones). Why can't we have nice things? Thoughts?
  • I don't disagree, However, I would like them to focus on performance/bug fixes/smoothness for a few builds, which is what I think they are doing. Once the core stuff is ready, yeah, I'd like to see a few more things in the pipeline and some extra features. I think you're right about iOS 9 and Android M and the progress they are making. Of course, Microsoft did just basically re-write a mobile OS in less than a year.
  • Is there anything new that you are expecting or is this more of a hoping to see something new by the time it's finished?
  • "Of course, Microsoft did just basically rewrite a mobile OS in less than a year". Again. They need to start iterating and stop re-inventing. Otherwise they'll never catch up to the competition.
  • Exactly. This is the 3rd rewrite in 5-6 years. MS has been their own worst enemy, continuously dropping the ball or backtracking.
  • The rewrites from scratch cause a rift as it leaves a group of customers/developers behind when they drop support. Since MS have been doing this a few times I am not surprised if public confidence for MS has dropped. Also, its a huge waste of resources. I'm glad they say Windows 10 will be the last 'version'. It will also be interesting to see if a rift develops between consumers and businesses with Win10 as businesses are slow to upgrade. Then again, no one is stopping them from releasing new OS from scratch that has a different name. Loophole ;P
  • Yeah, but it's all been leading up to this, the integration of one OS across all types of devices. It's a pretty dammed amazing engineering feat. And now that they've arrived, we don't have to deal with re-writes anymore - it's ask refinement from here on out. This OS it's going to be amazing. iOS is well polished, but boring as hell. And Adroid is a security nightmare that seems to get worse by the day.
  • This is the story that MS wants us to buy. Tell me, how much of the W10M code is shared with W10? Are there any known targets or numbers? How many of MS apps are actually universal?
  • Truly, I think the answer to both questions is "almost all." The bigger question is whether this is a good idea or not. To me, bringing win32 to phone is there most important thing MS can do. It's the only differentiator MS can offer.
  • Well, they share the same kernel at least. Plus, most of the MSN apps are universal. Sway disappointed me as not being on phone yet, however, its a universal app, so eventually it'll make it to the phone. The office apps are universal apps. So most apps from MS are universal. Though, until Windows 10 Mobile is actually released, we will probably only see a few third-party universal apps come out. Audible surprised everybody I think. But we still have Netflix on there, Adobe has one for Photoshop Express, and there are more I haven't even mentioned. So, yeah, the story they want us to buy is the *actual* story.
  • im runing 10 on my lumia 903 and its now prety smooth thats after 3-5 hours of trying to get it working lol.   Apps are not a issue for me exept my remote control for kodi media centre that still doesnt work with this build.  OPersonally i wish theyd stayed with 8.1 on phone and just improved it.
  • Daniel for Lumia 1520 go into windows insider app and choose fast ring again. Then check for updates. Should do the trick. I've had to do this with almost every build on my 1520.
  • Hasn't worked so far, not even after adding a SIM.
  • Mines updated right to the new build on my 1520 from 10166
  • I had to reset the phone, then update.
  • Daniel. Roll back to 8.1, hard reset. Download insider choose ring, restart. If this fails then your device is not registered properly.
  • I just laughed my lungs out seeing someone giving Daniel tricks! LOL.
  • Comments like these are unwanted. If not Deniel, tips might help someone else who visits the forum. Ofcourse I don't see Daniel takes offence at all. < For my sins, even I don't know who Daniel is  )
  • i had to do this on my 1520... Now downloading 10512 :)
  • >Microsoft did just basically re-write a mobile OS in less than a year.
    This is their problem. You can't iterate on a product if you keep starting over.
  • Which is why we have Windows10. That's their goal with the OS going forward: Feature updates on top of Windows10 itself. This needed to happen. :)
  • Exactly. All of these ill-informed comments grow tiresome.
  • But that was also 8. It was going to be one OS across devices. Yes, they were starting over, but they were going to add so many features. Now they're starting over again, removing some of the really great features from 8, and we still haven't seen many of the features we expected 3 years ago. Where am I misinformed?
  • The information you have isn't wrong, you're just missing more information. Ballmer and Nadella are different people with superficially similar visions. They both wanted a unified experience across multiple devices/screens. Ballmer was going to take us there in iterations. Windows 8 wasn't the end product, it was the start of a path to that unified experience. However, Ballmer never saw complete unification. He was fine with having different OSes share the same code. Nadella wanted the same OS. Period. Moreover, Ballmer viewed touch as the future. Maybe he'll eventually be right, but his timing definitely isn't. Mouse & keyboard are still too popular to have such a focus on touch. So, Windows 8 had a similar idea as Windows 10. But the guys behind each one were different and the approaches are different. Windows 8 was supposed to deliver a unified experience. Windows 10 is supposed to deliver a unified OS with a unified experience. They look the same from the outside, but are much different on the inside. Now, with the failure of Windows 8, they not only had an opportunity to start over, but they were forced too. No one was going to stick around while they slowly replaced bit by bit to get to the unified OS. They had go all or nothing. So yes, I see the point that if they keep starting over, they'll never be able to refine a product. But lets face it, with Nadella, we are seeing an overhaul of "everything." The OS, the company, everything. He's going all out because he has a strong vision and honestly, I think its a really great vision and he's doing the best to get there. Did he have to pull off some band-aids in the process? Yeah, but I think it was a better bet than to pull them off slowly. Ballmer made mistakes that Nadella had to fix. That is the information you're missing.
  • Hi Daniel, please do upload an in-depth video of the latest build highlighting the noticeable improvements and features( if any).
    It's a request because I'm not in the insider program but I really wanna see the progress the OS is making.
    Thanks
  • I agree albert730. It will be great to see a video for us who are not on TP but are interested in how the OS is coming along. I think he states in the article a video is coming soon.
  • iOS 9 & Android M are incremental updates compared to what Windows Mobile 10 is overall.
  • But compared to Windows 10 it is mediocre even Windows 8.1 pales to Lollipop and iOS 8 Posted via the Windows Central App for Android
  • I hate to pile on, but I also need to comment on the 'just basically re-write a mobile OS' line.  They've re-written it 3 times in almost half as many years.  At some point, that excuse wears thin, and all you do is frustrate developers who leave the OS behind, to say nothing of the end users.
  • Agreed. The change in direction for developers makes me wonder why there are any still bothering. I have made the transition now from Siliverlight to XAML (universal), but do not know whats in store for the new Win10 SDK universal - hoping it will be 99% the same APIs. It tests ones staying power.
  • See my comment above in reply to AfroPhysics. The reason this is different is because there's an entirely different force behind the change, Nadella and not Ballmer. Nadella has a strong, much more defined vision and is doing what is necessary to bring about that vision. It was similar to Ballmer's, but faster and went much further.
  • The problem is that every version, they rewrite something. Even 8.1 did that (Calendar, Music apps, etc. Everything to be an app, remember?). In Windows "10.5" they will rewrite again, and over again.
  • You're right. We should actually have small things like album art on lock screen, something useful in multitasking view, translucent action center. Windows 10 should be at par with Android and iOS as far as customization, look and feel it's concerned. I hope Microsoft add these things before final release. Praying for it..
  • IMO, this is no rewrite. It is a WP 8.1 fork with the W10 Universal Apps runtime and a couple of tweaks. Plus a couple of universal apps using that runtime. TBH, a runtime is no feature at all, so anything new is continuum, but only on new phones and being a feature of questionable merit. Evidence? W10M still has a Kids corner, which would be utterly redundant if we had multiple start screens (which in itself shows the fallacy of not having tiles on the desktop but on the start menu on W10).
  • Exactly. While iOS has been... exactly the same since it released lol
     
  • Yeah, because you know why? It works and people obviously love it.
  • Don't be a fool. Check iOS/Android forums and then you'll know it's no different. People love to complain. Only very few love an OS, because there's always something to complain. Actually iOS did not work for me and I switched all devices to Windows.
  • Yes iPhone OS 1.0 is just the same as iOS 8.4.1 with the same features. Terrible Posted via the Windows Central App for Android
  • Daniel, please help me here:
    I downloaded windows 10 mobile from 10160 and then did a master reset. And my phone is Lumia 720. And I like a month since I downloaded w10 but I have some heavy games like HOC and cloud raiders and robotto. I tried downloading the phone update for 10512 Bu the update seems not to be downloading I have proper 3G speed and still after 2 hour I checked , not even a percent downloaded. Please help me what i should do? I cant do a master reset now. If that's the only option should I roll back to 8.1 and then download 10 or just do a master reset? The download screen is not showing any error so that I can restart it. Please tell me.
  • They will show it in the new builds, now that the focus on desktop version is no a priority anymore
  • I think there's a strange dilemma with releasing preview software. It's definitely a double edged sword for both the developer and the users
  • Agreed! Very insightful comment. The thing is, people forget the "Preview" part. Also, it is not a "cool" thing to be part of the Insider Program and it is not designed to let us brag about an incomplete OS to friends, with lots of new features ready to use in every Preview release. I do not want tons of new "just-began coding" beta features that crash the phone. I just want this OS as stable and high-performing as possible. I am very happy with this release. Finally we have it in our hands. I installed it and made a hard reset. I agree with Daniel: the default Start screen is great! Always had to delete everything (almost) and start over with my own Live Tile layout, even in the Windows Phone 8.1 retail release. This time, I deleted Facebook and uninstalled the Facebook app. For now, I will keep the rest of the default Start screen and rearrange things later. The most notable thing I will rearrange later, is Messages and Phone. They are placed as tiny icons on my screen, which in my view is a bit tedious. I believe, however, that Microsoft is expecting people to use Edge and other apps a lot more often than Phone and SMS/MMS :). After all, they do telemetry, analysis and stuff, so they measure what we Insiders use the most. So, it seems Phone and Messaging are seldom used. Rather, Telegram, Whatsapp, Viber and other IM apps are the norm today.
  • People get the preview part, and they get the term "feature complete".
  • I think most of you people are thinking about in between builds, and maybe this is the problem with letting so many users in on the development process. But go back to Windows Phone 8.1, and look how many tons of new features and polish there is since then.  Then go back from 8.1 to 8.0.  There are TONS of new features. I can't even get myself to stay back on 8.1 or 8.0 because of all the stuff in Windows Mobile 10 that makes it where I don't want to go back.
  • The TONS of new features are just basic ones that we need since WP7. Even on W10M I can't edit a number when trying to call someone. If you get in the end of the home number and see an wrong number you need to erase every number.
    Action/Notification Center, swipe keyboard, office, good music player... They are just basic features. Yes I'm glad that they are equal or better than Android or iOS, but innovation = zero.
  • That's all well and good. However, you can't go from not having any of the "non-innovative features" to having the most innovative phone. you need to develop those non-innovative ones first. Those don't happen magically on their own. Just because they exist elsewhere doesn't mean Microsoft can magically code it overnight. You need the foundation before you can build upon it. You need to be on par first before you can surpass.
  • Yup... I just don't want to go back.
  • If you're refereing to the differences between iOS8 & 9, or Android L & M, that is a TOTALLY different story. This is a new build of Windows 10 Mobile's initial version. A more accurate comparison is Windows 8.1 to this build (Which there are many differences). Not a previous build to this one.
  • W10M is nearing completion within the next 2 months. Don't expect any ground-shattering new features except continuum and hello (which current phones cannot take advantage of). Stop denying yourself the reality that W10M should be compared to iOS 9 and Android M they are all OSs released in 2015. Windows 10 mobile is no longer in the initial version stage this is not really a brand new operating system, it still runs the same apps, has the same features and 8.1 and is built off of Windows 10. BTW Windows 8.1 is a desktop OS. If you mean Windows Phone 8.1, then it is still not up to par with iOS 8 in terms of features. To compete, MS must have nearly, if not all, the features iOS and Android have to date... and more.
  • Agreed. Why can't I connect an external DAC to my phone?  Something that has been in Windows for ages, and both i and A for years. Where is OTG? Why isn't XBox Music / Groove Music player a kickass player after so many iterations and changes? Basic features that will sway a person from deciding on a mobile OS. And this campaign now, "vote for landscape".  Come on, Microsoft.  The most front-facing of all features, and you make people vote, argue, debate, etc.  Just put it in and let people decide to turn it on or not!   Micrsoft has too many resources and has been doing this for too long to let Apple or Google be the leader in any operating system.
  • My comment was not about iOS vs Android vs WP. It was regarding the evolution from OS version to OS version. The original comment came off (at least to me) as saying that iOS 9 is a huge step up from iOS 8, but that this build of Windows 10 Mobile isn't a huge step up from the previous build. Which is why I said the comparison should be WP8.1 to WM10, not WM10 build (x) vs build (y). I would never say that WM10 shouldn't be compared to iOS 9 * Android M, because that would be totally unrealistic. Yes, Windows Mobile 10 isn't necessarily in parallel with iOS 9 & Anroid M. But iOS 9 & Android M aren't in parellel with eachother, either. Each has something that sets them apart. For example, the way iOS and OS X connect to share calls and texts (you don't really see this on either Android or WP/WM). But, you also don't see the Continuum feature on iOS or Android. Can't think of an Android exclusive feature off the top of my head, but I'm sure there's one or two things that it does, that other platforms don't do. However, I agree that Microsoft needs to continue adding as many features as it can to maintain a decent level of parellel with the other two.  And yes, I know WIndows 8 is the desktop OS, it was a typo.
  • Yeah even with all those features iOS9 has, it's still nothing to write home about... Personal opinion here, I think iOS is boooooring as hell.
  • Many people think iOS is boring, but that's a design opinion. The argument is whether Microsoft should add new features at the rate of iOS with iterative updates, or should they keep basically the same feature set while re-writing the basic OS every couple years, and shuffling in some new features in place of some others.
  • What an ignorant comment. Shuffling in some new features in place of others? God damn.. Just this year: Cortana is a HUGE step forward. Windows Hello is big.
    Continuum is huge.
    Simpler interface... folders... settings... universal apps... notification center. This isn't just adding a few features, this is a completely new beast compared to what it was 2-3 years ago. What features are we "losing" with Win10 that are anywhere near the size of the features we have gained in the last year or so? Btw, photo story is one of the coolest apps I've seen in recent memory. I thought I wanted Groovebook for Windows Phone (or a better version of it, since it sucks now that it was bought by Shutterfly), but this new app is a killer. Awesome.
  • However, that "shuffling around" is going to pay off. Yes, it wasn't ideal, and end-users didn't necessarily see HUGE changes in the UI, but plenty of new features were added, such as Cortana. Most importantly though, were all the "core" components (Such as Messenger and Phone) switching from being built-in to being apps. That means if a serious vulnerability or bug is found, Microsoft can quickly push an update to the impacted app(s), rather than trying to get the carriers and OEM's to push out the necessary updates. It also allows them to add new features to those components whenever they want (like the Skype integration in Messenger & Phone comming later this fall). Not to mention the other "subtle" under-the-hood chang, that will allow Microsoft to directly push out full software updates to all Windows 10 Mobile devices at once (just the software, not the Firmware) without having to wait for OEM's and carriers to do it. This is something iOS users have enjoyed, but Android and WP users (up until WM10) have not had. This alone is pretty darn huge, as people wont have to wait to get awesome new features, because Microsoft will just push it out to everyone at once. In a nutshell, Microsoft has spent the last few years really working on the underlaying components of the OS. Now they have laid a pretty fantastic groundwork to innovate "uninterupted" moving forward (by which I mean they can bypass the middlemen and go directly to the end-users).Rather than focusing on one huge update every year (like iOS and Android), they can push out multiple feature-rich upgrades throughout the year (as I recall, they already have several lined up for the next year or so, with a roughly 4 ~ 6 month release cycle). But I do agree that it would be nice to see some more of the features on iOS and Android, being added to WM10. Hopefully we'll see more of that moving forward.
  • They aren't going to release all the features in a preview. To even expect that is unrealistic.
  • I would expect that they show off at least a few new features. And what's the point of having the Insider Program if they don't eventually show off all new features? We're supposed to TEST them remember?
  • I definitely agree with you. It's been nothing more than a redesign so far, All the good stuff except continuum is for developers(which is great but means nothing for us).. Hopefully we'll see new user features after RTM.
  • Why not? They did for desktop Windows 10.
  • They MUST, lest not have anyone left even remotely interested in W10Mobile by the time they get around to secretively putting these features in.
  • Maybe I'm wrong but there was an article here where they said windows phone os is done feature wise but they won't release all the features till the final build.
  • 'Just take a second to listen to yourself; 'I want to be able to access the root of the phone and use it like a USB (like Android).'.... You are the very people who whine every now and then about WM copying android and about how you hate that stuff. Apple keeps their IOS locked; you dont complain about it and you waste your hard earned money buying their crap(for lack of a better word), microsoft does the same and sells it at a lower price yet your are here talking gibberish.
  • I NEVER said I use and iPhone or Android as my phone, ever. am not the problem, comments like yours are, accusing others of being fanboys when there is no basis of fact or evidence, that makes you a Microsoft fanboy. This blind following is exactly what we are trying to avoid. We don't want to become like Fandroids or iSheep.
  • We need a better word for Microsoft Fanboy - it just isn't fluent. We have Fandroid and iSheep, so perhaps "Softboy"? But that sounds pretty gross. Thoughts?
  • @Sabre Wulf How about "MicroBoy" or "MicroToy"?
  • LumiaBoy, no offense to other models. :-)
  • Why do we need the word 'boy'? Why not microfan? Winatic?
  • The synced Messaging app and Action Center are honestly the only two things I've cared about for a while now.
  • Yes, these are what I need. And snapchat.
  • You want some cheese with that whine?
  • I'd love to see a w10m, wp8.1 comparison.
  • Before you get to sour, Joe Belfiore has said that there are more features that they will announce closer to launch. So next month is a good bet. They didn't want to show off some of the stuff coming with TH2
  • Can I comment without being labeled as "sour"? Apparently, I can't even though all my points are valid.
  • A feature like an intelligent user interface logic would be nice... I cannot believe there is yet another build with all those glaring inconsistencies out. It truly makes me shiver realising they really intend to leave it at that.
  • Ios still doesn't have Bluetooth file sharing, file manager, sd card support, fm, USB otg, etc how can you say it has more features than Windows 10 mobile, when it lacks basic features which are already present in 8.1? I guess its not your fault, Apple creates this image where they only glorify and show what you need, not what you want......
  • True, iOS doesn't have these features, but Android does and iOS will never have these features because it's Apple keeping the OS locked down. However none of these are new to Windows phones as they are all in 8.1 and yes iOS has plenty more new features then Windows 10 Mobile has.
  • Don't forget wireless charging too on WP, a great function iOS does not have, until they reinvent it of course :)
  • The point is not iOS has feature x and WP does not. WP and iOS should go in different parallel paths, as the ideas behind them are different. The point is that Apple releases iOS 7, 8, 9, and add new features each time. They always have a different focus, and sometimes add better features than other times. But with WP we have 7, 8, 8.1, 10, and they add a few features, but also remove features. Then we also have a rewrite, which means many of the features we've grown to love are no longer supported. This is no fun, we don't want to trade features we like for the promise of new ones, we just want the OS to keep going in one direction, with constant, iterative improvements.
  • Ios9 has some features but not that many. And they already perfected the os. So they have time for features. Hey this build has a neat feature. If I pull down the notification center I can't pull it back up on my 830. Hehe
  • It's working pretty well so far without a reset on my 640xl.  Very smooth.  I still have some cortana bluetooth lag but, seems better so far.  I need to spend more time with it to know for sure.  Battery seems great so far.  Looking good so far.
  • Since you also have a 640 XL, are you having problems with the keyboard not showing when in Landscape mode? I've had this problem ever since I started installing preview builds - even with this recent one. Still not fixed
  • Landscape keyboard never worked on my XL with w10m
  • does the video playback being broken issue affect 3rd party apps? (specifically MyTube)
  • Nope. Only the Movies&TV app.
  • But after an update for the app Movies& TV ,its working now
  • No. TubeCast working fine.
  • What about error "0x80244019"??
  • It means you that you are smart enough to search the error on internet.
  • It's ok, doesnt feel much different than 10166, seems a bit more buggy and glitchy if you ask me. I had virtually zero problems with 10166 on my 929. The lockscreen delay is quite annoying, ddint have that with 10166. Does anyone else have issues connecting to bluetooth? I can connect to my jawbone jambox just fine but still cannot connect to bluetooth in my car.
  • keep watching
  • My AT&T 1520 went from 10166 to 10512, no issues. I'm on Verizon, so I'm running this without a SIM.  I don't know if that would help with your 1520, buyt popping the SIM would be easy enough to try.  I'll keep my Icon on 8.1 until release.
  • That could be it as that happened for app updates before. Will give it a go.
  • Lumia 925. This is the first insider preview update where I've had no issues. Everything updated smoothly, all apps are working and there was no need for a reset. The known issues of course can't be avoided, but overall I'm pleased with this build; they're getting there... And yes it does "seem faster".
  • Thanks for the info. May try it on my 925.
  • I'm waiting for my battery to hit 40% so I can install asap. Airplane mode engaged so it can charge quicker. 10166 is a huge battery drain on my 1020, and it's really flaky. Can't wait to update :) :)  
  • Thanks for the write-up Daniel. I have a Lumia Icon and didn't know that I couldn't upgrade straight to 10512. I'll give it another shot now that I restored back to a fresh 8.1 install. Thanks!
  • yes , you need to roll back to 8.1 , then insider configuration and build 10166 , then it takes you to new build 10512
  • Hey man work in my lumia 1520
  • Anyone experiencing start screen infinite loading loop on this build?
  • yeah I was. I had to use the recovery tool http://www.windowsphone.com/en-US/how-to/wp8/phones-and-hardware/recover... to get it working again.
  • Yes and I literally just fixed it by changing my start screen picture after 8 hours of saying fuck it. I had narrowed down my apps on the start screen prior to updating (removed folders, etc) but that stupid thing fixed it where I didn't have such luck on the previous build (didn't reset between my old build install and this new one).  
  • Umm can some one please elaborate on the "another branch" term?
  • next upgrade path in terms of rtm th2 kind
  • Branching the code basically means that they make a duplicate copy of the source code so that it can be worked on separately from the code for other versions.  This would allow them to continue working on new features and service packs for Windows 10 (Desktop) without affecting the code they are wrapping up to release Windows 10 Mobile. 
  • Only problem I have with this build is when I pull down my quick actions "quite hours" it's blinking on and off nonstop. Anyone experiencing this or have an idea to stop it?
  • Yes, I see this too. Will add to the list.
  • Haven't been able to stop it blinking, but at least the quiet hours functionality works when configured through Cortana's notebook.
  • This is the first time I've done it on my 930 without hard reset afterwards and so far so good. Battery management is much better. Ppl don't stop giving MS feedback. With w10, astoria and islandwood we have something very special and powerful but without the ppl they could easily screw it or us. Feedback good or bad just do it.
  • As a Windows Phone user for 10 years I really have one thing to say.  If you are not a Windows Phone User right now, There is NOTHING here to convience you to use Windows Phone.
  • Preview preview preview
  • This one is still in denial.
  • Playing cheap...bravo! Grow up please.  
  • Windows phone hasn't been out ten years, anyway, this isn't meant to convince people to try windows phone/mobile, this is meant for existing customers to test pre released software and alert of bugs flaws etc this is more of a gift for tech junkies and also to make it easier to find out what people wish Microsoft to add or improve, on this front it's successful.
  • Um, in one form or another it has been out longer then that.  I had Windows mobile 5, 6, 6.2, WPhone 7, WPone 8 and now 10. From what I have seen from the Windows 10 Devleoplment, and heard from friends at .....  We are not going to see alot more put into this.    
  • I have to agree. I'm a huge Windows fan and I've loved Windows Phone to date, but Windows 10 Mobile just isn't doing it for me. A lot of questionable design decisions in my opinion, which I've voiced through Microsoft feedback. And a lot of changes, which may seem small, but completely ruin the experience in my opinion. Things just aren't as solid and fluid as they were in WP8.1. And then you have the new apps, like News and Money, which I use daily. I feel they are incredibly inferior to the WP8.1 counterparts. News is almost unusable if you follow a lot of topics because you can't flick down a screen now to get to one, you have to swipe, swipe, swipe, swipe, swipe, swipe, swipe, ..., through all of the pivots. It's terrible. Same thing with stocks. Tons of wasted screen real estate for just a little info, much less efficien than the WP8.1 versions. Anyhoo, I'm hopeful because I believe strongly in the Windows 10 paradigm, and I love desktop Windows 10, but so far Windows 10 Mobile is just meh in my view.
  • I disagree. I think the new designs of the core apps are far superior to 8.1. Especially the store app. The old one didn't look legit, like a child had made it. This one looks serious and more clean overall.
  • I do like the store a bit better. The old one did well on minimalism but lacked some of the content you want surfaced up front about apps. My main problem, though, is that search isn't more accurate/quicker.
  • You mean 6.5
  • Windows phone OS has been out for much longer than ten years. If you keep re-writing every few years and call it a new OS, then yeah, you'll never get to ten years. That doesn't mean the competition won't.
  • Then say nothing. When you can't see it, please move to iOS or Android so you can say the same about iOS and Android.
  • I never undertood why people take other's opinions so personally - why shouldn't he write what he thinks? Why should he move somewhere else?  Don't get it :-)
  • A silly bug but very annoying, when you have two-step verification activated via SMS (for MS account), it asks you to enter the last 4 digits of the mobile number, while the text field allows only two digits... I had to email the code.
  • Yes, its on the known issues list.
  • This bug was mentioned in the release notes.
  • i really like build 10512 , i also feels like now my lumia 930 not heating like happens in  previous builds and from past few hours , it feels like wp 8.1 - in terms of smoothness .
  • Your home screen ain't doing that loading thing?
  • no , works fine ; as after update , i go to settings < system < about : reset (( a.k.a hard reset ))
  • Alright getting preview build for my 635 which is my OS testing device, looking for to providing more feedback on this build directly to Microsoft.
  • I'm running A Ok so far on my 636 (the Chinese 1GB variant of the 635). Also my OS test device ;)  Did a hard reset just to be sure. Also, thanks to Dan and Gabe for keeping a sense of humour through this latest update too!        
  • Feels like this article was "written" with dragon naturally speaking. Felt like it was all one exhale- kind of humorous.
  • Any one having trouble with Start folders?
  • reset your phone will solve
  • I did in build 10166. Working properly in 10512 (L930)
  • It runs pretty great on my 920. Folks complaining about lags should wait until all apps updates are finished. Also should consider resetting the phone.
  • Oh god, finally. The last release was pretty buggy running on Lumia 920. And I had given up to play with it. Maybe this time it worth a try :)
  • Lumia 1520 can be updated to 10512. It fixed a lot of bugs I had problems with.
  • yes , that he was talking about temp. issue in article
  • Is Glance not supported yet? I can't find it on my 920.
  • no , may be
  • Heh, it's hidden somewhere. I used sysapp pusher to kick start it and it works now.
  • SysAppPusher -> Store tells me that Glance Background is no longer available - L920 on 10512
  • Sorry I haven't tried Glance Blackground. (Glance Background adds background picture to Glance and is a separate app.)
  • Just put it on my 1520, went into insider, selected fast ring then checked for updates, took awhile but went through. Did not do a reset yet and all seems to be ok. The lock screen delay is annoying but survivable. Tested alarms, it worked, with my superman opening theme an everything, email seems ok, people are still bubbles, etc. If any major issues arise I'll do a reset.
  • Still same old home screen problem on my 930
  • I think is maybe a good thing thaat Microsoft bricked my Lumia 830, so now I have to buy a new one. Very tempting about the new Lumias but the 640XL and the used 830/1520 are good deals, what should I do?
  • 1520 pwns all in my opinion right now 
  • I would buy a cheap 635 or similar for now. The 950/XL will be coming out in a couple months. Just something to get by with for now.
  • Yeah I'm looking for deals here in Costa Rica, but only the 535 are available. 
  • The 535 has some screen sensitivity issues. But overall it's not terrible, I have been using it for about three weeks and it's ok.
  • What happened to your 830? Have you tried recovering it through the windows phone recovery tool?
  • Got bricked while the upgrade from 8.1 to W10 went wrong, just got a black screen. almost 4 months have passed and no one at Microsoft is able to respond me what happened. I tried everything, XDA windows comand methods, Nokia Care Suite, Windows Phone Recovery Tool (each update), I even send it to a repair store so they can used the JTAG brute force method.  Nothing, the phone is a deep brick state, when connected to the pc says QHUSB_BULK. What a waste of money. So now I am with a Galaxy S6 but want to keep two phone, one of each OS so I if get bored, I can switch.
  • Hey Dan, any chance you could tell me if resetting the phone makes the Glance settins disappear like it used to? If that happens, I can't reset,
  • I reset my 640 XL a couple days ago and lost glance.  I was running 10166 at the time and that was the first reset I ran on the device since I got it.
  • Yeah, I know it happened in 10166, I was wondering if they fixed it.
  • I've done that. Installed 10166, did a hard reset. And then used Fast Ring to upgrade to 10512. Did a hard reset again, and glance worked just fine. I did notice a delay on my lock screen, as in, the image would appear and a couple of seconds later, the date and time. And oh, I'm using it on my 830, my daily driver.
  • I also updated my Icon, and I do love the fact that it no longer burns my hand ;)
  • Question: I'm on build 10166 and need to do a hard reset, if nothing else to get rid of the start screen loop. So, should I do a hard reset now, then upgrade to 10512? Or should I upgrade now, then do a reset? Or does that even matter?
  • upgrade to build 10512 , then hard reset
  • Lumia 1520 here and I received the 10512 update this afternoon. So far the OS is definitely smoother, yet I still experience the loading start screen issue which is fairly annoying when trying to test apps. Also still a lot of Lumia dependencies missing like touch, audio, and display. I can't stand the Windows 10 store. From the download and install screen you can't access the app by tapping it, the app doesn't tell you what apps it updated throughout the night, etc. Groove sucks. I pay for the 14.99 monthly plan that allows for me to download 10 free songs a month, yet since Groove the store no longer allows for my free downloads.
  • Yup, forgot about how the bad Store still is. Added that to the list too.
  • FFS what freakin part OF PREVIEW CONFUSES EVERYBODY??  if it was RTM yeah I could see why you would drown us with tears ...but seriously people if you want it perfect stfu and wait till RTM  ....till then eat it 
  • You are the one who is confused. What is the point of the Insider Preview if everybody keeps quiet about the bugs?
  • Right, but it really only has a point when someone uses the feedback app..
  • You mean the old Zune Music subscription plan?  To be fair, Xbox Music never allowed you to download your 10 free songs either.  I've continued to use the Zune PC software each month for the 10 free songs.
  • That's why I have my apps set to manually update so I see everything that updates.
  • I defaulted my new build and the Nokia software did download from the store and nothing failed.
  • Hi i have a 640,i keep getting this update error.
    Can anyone please help me,do I have to rollback to 8.1 Some update files are missing or have problems. We'll try to download the update again later. Error code: (0x80070003
  • you need to roll back http://www.windowscentral.com/roll-back-windows-phone-81-windows-10-prev...   as becuase you updating it from build 10166
  • Thank you
  • Ok maybe I'm just blind but where are those stock backgrounds located? I don't see them anywhere.
  • go to settings < personalization < start : photos or go to background change : you will see .    
  • Me too... I can't find them at all.
  • They are in the root of the "Pictures" folder. You can view them with the File Manager app.  
  • Can we finally do left edge swipe for hamburger menu? I mean like android.
  • no . i was waiting for that feature , i installed windows central android apk again in build 10512 to use that feature
  • This is really annoying. Why would they implement incomplete feature. Hope next builds will bring it.
  • The stupid!  It burns!  They aren't trying to implement incomplete features.  They start implementing a feature and until they finish implementing it, it remains incomplete.  If they decide that a build is good enough to release in that time then it is released with that feature incomplete.  The alternative is for them not to release any build at all.  If you prefer no incomplete features then just don;t install the build.  This whole preview concept has really shown how little some people engage their brains.
  • Lets see how it turns out. I know it is a preview. But all I am saying is don't introduce a dial pad with missing key.
  • My guess: they won't do the swipe from left as they think that would interfere with the remaining sideways pivots and/or they may introduce task switching by swiping from left at some point. Unlikely though.
  • I get an error when I try to update my M8 running 10166. 0x80246002. You said you can't go directly to 10512, but it was unclear in the article.
  • Actually it's an update error..
    Try Rebooting and Soft - Resetting..
    And then check for updates..
    If you still encounter the same issue.. Then you shld do Hard Reset..
    And Actually only Windows 8.1 users will not be offered with 10512 build directly..
    First they will receive 10166 and then 10512
  •   I don't know if I'm the only one but I can't change the ringtone with a custom one. And second and this one is even worse, there is no notification sound when I receive a massage.
  • Hey Daniel..its good to hear that MS is working on bug fixes..thats good.win phone 8.1 was also smooth..if you are just focusing on bug fixes what's the need of new OS. The new OS should contain exciting features..if don't do how will you attract new users..?app paasawords..Wi-Fi direct..these things are older in ios and android..but still unavailable in windows...its annoying a lot
  • "Our major focus on Windows 10 Mobile right now is on improvements to core quality" from now they will bring new features plus making previous more polished and expect builds faster
  • Were you asleep when they mentioned that Windows 10 is now a single OS across all platforms, allowing easy integration of Windows Phone features into Windows on tablet and PC and also development of Universal Apps that can be written once and then run on any device?  If nothing else, that explains why a new OS.
  • I have a Lumia 635. The Edge browser in 10166 was almost unusable. Closing, resuming, reloading, crashing, unable to share. I was hoping for improvments in 10512 but sadly the behavior is the same. Other than than Edge I really like WP10 Mobile. I'll give it one more build after this, but if Edge doesn't improve its back to 8.1. 
  • edge developer told this build don't have major changes , but in next flight ( build ) you will see some major changes
  • I find them in Photos
  • In the new Outlook app can you pin separate account mailboxes like you can in the current OS?
  • it is available since many months in new outlook app  .
  • Still too laggy on my 720. Everything takes 2-3 seconds to happen.
  • Running on a Lumia 1520. Lack of Mobile Hotspot almost broke the deal for me, but I"m just going to switch SIM on my 520 to get my occasional hotspot needs, I had to have this build. Can anyone confirm 2 issues I am having as still being broken? 1. No "Hey Cortana" 2. Nothing in settings to backup photos to OneDrive?! I havn't been able to backup photos since july 1st. I am getting ready to do the hard reset thing to fix OneDrive unless anyone can tell me that it is working on theirs. I can find no setting for backup photos to OneDrive. Thanks all... (P.S. boy are the ads on this site getting offensive and way too in my face) JF  
  • Camera upload setting has moved inside the OneDrive app.   Open OneDrive app Hamburger menu, which enables the settings icon on top right corner in Settings, you will see "Camera Upload"   Took me a week on 10166 to find that.
  • Does backup of images to OneDrive work in this latest build?
  • It doesn't appear to.  I just turned it on inside OneDrive, took several pictures and nothing has uploaded to my OneDrive account.  I don't like that it was turned off by default.  In WP 8.1, this was toggled on/off during initial setup.
  • Wow, that is buried pretty deep, I see no reason to not put it in the Backup section. Hope they get their act together on that one. Stil not uploading though, is it working for you?
  • I got the new upate on my 1520 very early this morning, but I live in Chile, so I guess Chilean owners of the 1520 got it faster than Americans? Not quite sure.
  • no , it's not true , but good joke . thanks !
  • You've got some developer updates which was released 1 or 2 weeks earlier..
    Check for the latest build now..
    Actually Technical preview builds will be released by 10.00 am Redmond timings ( In general) ..
    And will distributed for all insiders at the same time only...
  • Any chances of getting floatie support like android? I really miss messenger chat head and musixmatch floatie. And Microsoft just don't give some tech writers opportunity to call this OS another catch up. We want this OS to be on par with android and ios plus additional features(both for developers and users).
  • The unified Messaging app experience and syncing of the Action Center are the only two things I care about with Windows 10. So far, no word on either. :-(
  • Messaging app coming with Threshold 2. Universal notification center is not happening last I heard of it. I don't know why it's not happening and I haven't heard a single thing about it. However, the Messaging Preview app for W10 PC will be launched late August/early September.
  • My 1520 died again, since it must go through 10166 first...
  • Did they fix Drive Mode? I have it set to ignore texts while I'm driving, but it still reads them. And I can't find a setting anywhere to turn off read texts. It's not where it was in WP 8.1.
  • look under settings in cortana Notebook  then settings you ll find read incomimg text messages aloud
  • I just turned off m my test unit (1020). Instead of the usual "Goodbye" I got "Remember, tomorrow is Bill Martijn's birthday." And it, indeed, is.
  • I think that features been there for a while. If you have any calendar appointments, the power off screen will notify you. I think its really neat.
  • Did the update on htc M8 for windows from 8.1 to 266 to 512 directly with no hard reset between and not after the last update was done. I did a soft reset once the 512 finished. It is running very smooth. I did notice the couple second delay on the lock screen. I don't have a lot of apps loaded but those that I do have installed seem to work OK. Will definitely do the hard reset after the next major release.      
  • The bad list doesn't seem so bad Rubino. maybe you should move to California and try to find a Mr Miyagi, so you can be finally happy Daniel San. Smile! and enjoy the preview build, I am sure RTM will be good, that's probably the one I will install, I tried preview but some apps crashed so much so I went back to 8.1 but I like what I see. and it's good performace is being taken care of, I am sure when RTM hits and Windows 10 is this and that, and universal apps, then Windows Mobile will be really good thing. But today we don't even have proper apps updated to 10, some apps that had charms to "play to" aren't updated with the new playto feature on Windows 10. and some are still fullscreen and you can't even move them from one screen to another so yeah, we still need some months to go, it's good they didn't release windows phone the same day as desktop so apps can be polished, universal and better when mobile hits RTM.
  • Still hoping for an outlook update to allow kinked inbox again. That's one of the biggest issues I have with the windows 10 mobile right now. Was a great feature so not sure why it was removed in the new outlook version
  • Anyone else having a terrible experience with Microsoft Edge? A lot of crashes and lags, seems like when I delete history it's better for a little while though.
  • Yep. I posted earlier and got this reply. Keep your fingers crossed.     Aakash006Sharma   edge developer told this build don't have major changes , but in next flight ( build ) you will see some major changes
  • I went directly from 10166 directly to this build on wifi. Nokia 1520.  Update went flawlessly. I found that Nokia Tones app works again.(Yay) Like its been reported, there is a delay from the lock screen.  My thoughts are to remove the current pin, reboot then re-add it. Maybe that will resolve it.  I had issues with my Microsoft Band on 10166. It worked for a while but when I did a roll back to 8.1 to reinstall 10166, Band could care less about working.  I finally reset my Band then repaired it. Its joined now but Fanband isn't sending to it or Band isn't accepting from it. No errors or warnings. Just nothing.   The acid test at this point will be actually running my Red Herring game.  On 10166, launching the game would blow this phone out the sky. I'll know more about that soon.  Love the way my pictures display in OneDrive. Edge is a beast. Mail is still gorgeous as is Calendar. Contacts scrolls smoothly.  Unbelievably smooth.  But overall, its feels very solid and very fast. Not 100%. I like it for me mainly because I carry a backup phone, but I still would not recommend this build to anyone as if it is a trusted product. It simply isn't yet.  
  • Could you tell me if tethering works on Yu our 1520?
  • Seems to work.
  • Oh yes...second that about "Nokia Tones". Still no "hey Cortana" for my poor 1520 though. Sad and impatient. Agree completely with your other observations.
  • Still cannot run Red Herring though. It locks the phone down completely and the only way to recover is a hard reset.  So I had to uninstall it on both my 1520 and HTC M8. Yes Mary Beth, No Hey Cortana yet.
  • jazmac, is the Band actually working in this build?  Can you pair it and get notifications or not?  Band support is stopping from trying the Preview builds right now.
  • Sorry for the delay.  Yes, my Band is getting notifications as it did before. Kinda cool again.
  • Windows 10 mobile builds have been a lot smoother since 10066. But it makes me sad that they feature locked the development so early. I know that most of the updates can come from store now but there are still areas where I want to see some improvements that will require a full OS upgrade but we all know how that goes what with carrier approvals and fine tuning them down for individual devices that takes months before an update finally reaches in the hands of a user. Oh well, one can dream.
    P.S I liked that bit about Microsoft Edge getting huge update with next build. Still don't know why hasn't it become a store app yet and why can't it still be not updated through store independent of full OS update.
  • Anyone know if tethering will be an issue on att 1520?
  • I'm just happy to see that my Microsoft Band is now receiving email notifications using this new build.  Finally!
  • Hey Daniel wp 8.1 had many new exciting features like action center..cortana..data sense..storage sense..tile folders...It's new features made me to upgrade to wp8.1. I just wanna know that should I expect any more features in windows 10 mobile...?
  • Love how the music app looks
  • Video playback broken means that v cannot watch videos at all???
  • Yes at present Film & Tv app won't works..
    A fix will be coming soon..
    Until that you can use 3rd party apps like Vlc player..
  • No, you cannot watch videos in Movies+TV app. Not throughout the OS. Tubecast, Edge etc. work fine.
  • Conclusion never update to this version.
  • Give me a reason why I shouldn't leave Windows OS, I've never ever use IOS or Android because I love Windows so much but can this OS can be better and better in near future ?
  • I recently updated my spare 1020 to W10 and now it wont let me turn on the wifi. Anyone know about this?
  • Still lagging behind in terms of multitasking.
    Ms can bring snap assist feature to windows phone too with drag and drop support ,will make it cool maybe.
  • Anyone tried of lumia 630?
  • I haven't had my 6Tag work for a while now. Anybody else experience this? My Wunderlist Live Tile isn't displaying as well. Will a restart fix this?
  • Sorry Daniel but I actually got the Hero wallpaper on build 10166.
  • Probably already mentioned, but text, emails, and notifications are working with the band unlike previous builds.
  • Can't sign into Windows Central app. 
  • The delay on the lock screen is driving me bonkers. That being said, I'm happy that with a clean reset and install, it's running great. The SD card fix was needed and I'll be happy that I don't have to wipe it every week due to the previous bug. Outlook is running great, but I'd love a bit of customization. So far I'm very happy, but I'll need a few days to see how it holds up. Now is the time to test it out if you haven't already!
  • My double tap don't work to wake up my phone
  • My 1520now have a sad face. What the heck does that mean??? Can anyone help?
  • Windows phone recovery tool is your only option
  • Anyone know if Cortana reads Text messages over Bluetooth yet?
  • I'm wondering this too, it was the deal breaker in 10166.
  • That can be changed in Cortana. Go to notebook>settings and 'read incoming messages'.
  • I don't know what I like. I do like new though. Hopefully there is something new.
  • I'm not going back to 8.1 I'll deal with the bugs
  • I hate the send icon. Looks like Android.
  • Mine lumia 720 | from 166 to 512 there is no problem, but weird no migrate data after installed, app loading and back to start screen, so i decide to reset, n now works better, just little problem with quite hour n same daniel review. Maybe after this there small update to fix the problem, afterall lets see what happen with this build later, feedbackfeedback
  • And according to Joebelfiore., Mobile Build is almost complete now..
    Proof :
    In the earlier builds we were seeing a Tag line ..
    .
    " NOT FOR RE - SALE "
    .
    [ Below Windows logo - At the Time of Switching on ur Mobiles ]
    .
    But this has disappeared now..
  • I got the black screen frown face of death on my 1520 lol... Did anyone else get that?
  • Better than 1016 build.
  • Guys, I made an embarrassing mistake and unpinned the People App when it did not light up upon restarting after installing 10512. Now the People App is also gone from the App list and none of my contacts appear to be on the phone (when I go to a message and click on the contact it says the People App can't be opened). What do I need to do? I am freaking out here a little. Help would truly be appreciated. Posted also in the forum: http://forums.windowscentral.com/windows-10-mobile/376147-help-accidenta...
  • Doesn't sound like a mistake, sounds like a bug.  A user should not be able to mess the phone up through simple actions like that.  Do a hard reset.
  • Thanks for the sympathy - if I hard reset though I wonder if my contacts data gets wiped and lost too?
  • Your contacts data is saved on Microsoft's servers. Don't worry.
  • Thanks, it worked!
  • Thanks, hard reset worked! Phew... :)
  • Sorry if this irrelevant to topic: Is there any news that we can change the default browser (e.g., Opera) or the default keyboard?!
  • Any workaround for mobile hotspot?!
  • Yea, use your primary device.
  • Premium Windows 10 Mobile will Debut After apple release.
  • People seem to forget that 4K video is already there in the 930 and 1520.
  • so team Windows has updated the naming of builds wow i probably should be satisfied by now, why i'm not ?!
  • We're testing and delivering feedback, don't forget that.
  • does movies and tv app work fine?
  • All apps are running smoothly on my 635 , check out excel
  • That is NOT my experience on the 635.  The thing is slow as the dickens, even AFTER a hard reset.  I. Hate. Windows 10.
  • Im looking forward to one day having a shiny new phone with Windows 10 factory installed. I somewhat envy you more adventurous souls but i really hate issues. I am tempted though.
  • you are wiser than me. I wasted countless hours of upgrading and then going back to 8.1. This time I will stay with 8.1 and wait for the next build ----- maybe.....
  • New flagship, factory installed W10. And a successful project Astoria. If that day comes in six months, I will stay on the platform.
  • Rockin I on the Lumia Icon, running great, but still getting "Loading......." On reboot, or after using some apps. Have to tap away at start button and sleep/wakeup numerous times to get start menu to show up. Other than that m, it seems silky smooth.
  • Playback works in the movies and TV app for me. Weird
  • Hi Daniel, please do upload an in-depth video of the latest build highlighting the noticeable improvements and features( if any).
    It's a request because I'm not in the insider program but I really wanna see the progress the OS is making.
    Thanks
  • The 820 processor 4K Video, Gorilla Glass 4 , and 4GB RAM and that's not even the features The Premium Windows 10 Mobile device will make your mouth drop.
  • Microsoft is not gonna let you know what's all in store for the OS , that is last. apple and Samsung gotta release first before Microsoft pulls the rabbit out the hat.
  • At this stage, that's not really how it goes.  All three platforms will have major release a scant couple months away.  What's done at this point, aside from bug fixing, is probably what you'll see at release. For Windows Mobile 10, at this point, it just means a different UI------ and universal apps are 'coming soon' along with a host of other stuff that's been promised at some point down the road. All in all, pretty meh.  If anything the tech blogs will rip the OS apart simply on the design aesthetics of the UI, which are pretty fugly IMO.  It's a Frankenstein's monster, a patchwork of design ideas.
  • My icon says. Loading.... Loading.... Loading.... Loading.... Loading....
  • It's ok, I'll probably do a hard reset to hopefully make it a little better
  • Still no usb otg, android has otg on the same hardware and Windows has not.
  • I think for lumia 512mb RAM.. build 166 better than build 512.. Build 512 so heavy.. swipe to menu now lag.. Low performance.. Huft
  • People don't get too disappointed yet. Lets see what's the final product is like and of its not up to par we will ditch the WP once in for all, tired of being an underdog.
  • Does anyone see the "Touch" option in settings? can't configure the vibrating touch and double tap. Lumia 520 user here. even the default images for Lockscreen i dont have it.
  • (0x80244019) error code. Seems cannot update from 10166 to the new build on my Lumia 1520. Any clues how to fix???
  • In simple words...nothing important in this build. Hope the next one bring new features.
  • Does this keep your 8.1 start screen layout if you upgrade though?
  • Well, I have been left totally out of this with my HTC 8x, so I have no advice or suggestions. I am really disappointed that I will just have to buy a new phone. I always planned on getting a new phone, but I thought I would get to test it.
  • Each build gets slower on the Lumia 635.  The delay for EVERYTHING is ridiculous.  Groove is the worst music app I've ever used.  I cannot express how badly I miss Zune.  And Edge?  Useless as a browser.  I'm thankful I can run IE on the W10 desktop.  Too bad I can't on the phone.  And STILL there is NOTHING in W10 for desktop or phone that make me want to ever consider using them on production machines.  I will run WP8.1 on my Lumia 1020 until it won't charge anymore.  I see no flagships coming, either, so I'm not in any hurry to set down my 1020.
  • I need all the background images you guys uses in your phone.
  • One more "the good"... No more need to do hard reset after or before upgrading to this build.
  • Running 10512 on my 640 and all is well and things are definitely smoother and faster and no hard reset. Start screen stayed the same.
  • Thanks Daniel. I was able to find and upgrade my Lumia 1520 AT&T (using build 10166) with no problem so far. I know you had check every single detail, but maybe the insider builds are set to Slow on your phone.  
  • So far, so good. My Pebble watch works, now I need to test the bateries for a few days. SO far I killed my battery and I still have 40 apps to download...it's almost midnight here.. I really hope the battery lasts a full day, 10166 was done by 6pm....cant live with that...
  • PSA: All Windows Central commenters
    No longer do you have to use
    "seems faster" anymore
    @DanRubino just gave us the new terminology for onward usage.
    Without further ado here it comes! "Noticeably Faster" Comply with the new nomenclature. :)
  • Yes, thanks for this as I literally forgot about 'still in early development of Edge browser'...may have to now wait util next build before finally making the jump to TP Windows 10 mobile build..
  • My L630 is stuck at 0% downloading
  • Does it supports to Lumia 530 pls rply me
  • Did they fix Kids Corner so it isn't passworded?
  • It's much better for sure, a lot of good fixes and tweaks!
  • Wished I could skip this update without having to rollback to 8.1. .. Too many showstopper bugs... The update is already waiting to install on my device..ive delayed that bastard till the 18th of this month.. Lol
  • Seems like Microsoft is Responding very fast for Insiders Demands..
    A New Update is been available now for " FILM & TV App "
    Which fixed playback issue caused after 10512 Tech preview update..
  • My AT&T Lumia 1520 also did not recognize the 10512 build.  Surprisingly, opening the Windows Insider app and rejoining the fast ring fixed the issue. 
  • Daniel, You mention the WiFi issues, any word on the Bluetooth stack? Keeping and working consistently with MS Band?
  • Just an update. Around 11pm I checked for updates and movie and tv app updated. Video works fine. Ms fixed that bug :)
  • Oh and Bluetooth text reply on my cars Kenwood now works properly. Anybody else missing hey Cortana? I don't think it was in the Las build either.
  • Still not available on my 930.....
  • Does W10 has the start screen like WP8.1? I don't like the way it is now :/ I mean the wallpaper part...
  • i have to ask , why do we have to wait until the next build for improvements in edge ? isnt edge an app now ? can it not recieve updates through the store ?
  • I have installed on a 1520 and 532 but you must do a hard rest after or your only doing half a job. The phones run much faster, cooler and to perfection after a hard reset. The extra work is absolutely worth it.
  • Please provide ability to pin the downloads of edge browser to start menu .. And able to show where downloads are in storage..
  • Wonder what will they do to make windows10 mobile sell? Now that all apps are on android Microsoft can excel in the cloud world. Continnum would be on high end devices. Even windows hello. Microsoft has made good budget phones with Nokia like 520, 525,640. Hope microsoft better markets enterprises with their phones. It would be hard to convince ppl buying windows 10 mobile until windows 10 desktops reach on one billion devicesqlq
  • So how about the "Glance Screen Option"? Still missing?
  • 1. Cant open the blocked messages menu. 2. Cant open "for devs" menu 3. Build is glitchier as the rest //using 1520
  • i just want my battery life to be improved . the old build shuts down my phone at 40 % and it drains significantly faster compared with 8.1
  • Microsoft needs to polish volume control layout as it doesn't suit the clear black screen devices
  • My 2 cents and my plan. Keep the 1520 with w8.1,as I believe it rocks, best phone I had and smoother,,clean and effective OS if compared to windows 10 desktop OS on my surface 3. Then buying a new 950,,or 940 or whatever they are going to call it with w10 mobile version at its top (supposedly).
    People are talking about new features..THE new feature is windows universal app, which MSFT delivered in order to dramatically increase the appeal versus developers. Then, in the future they will think about being on par with lagrdoid or isheep. But for the moment the goal is one unified experience and code dev for the three worls: Mobile/tablet/desktop PC. And for this this they are risking us, who have been true believer in the platform, but are not enough from a numeric point of view to be considered a business goal reached.
    -------------------------
    Did you notice that the 1520, which I believe is still a great phone has disappeared in the stores of Europe? I checked Italy and Germany. Why?
  • Do anyone have problem with quiet hours in the notification
  • Read the article. Daniel has the same issue. So do does everyone else.
  • Thought I was the only one with the flashing quiet hours quick action. Have to reset set the automatic rules. Quick Action button is still flashing but auto roles works just fine.
  • Thanks for the screenshots and real-world experiences Daniel. As an aside, I feel like now is a good time for an updated comparison article between WP8.1 and Windows Mobile 10. Namely, what can WM10 currently do that WP8.1 cannot? These new features may be old news to those on the front lines, but I think a lot of people would appreciate a refresher on the enhancements. Things like a fully functional Office version of Outlook that now supports formatting. The keyboard cursor joystick. Unified and organized settings groups (I think technically this came with WP8.1.2). Ability to set backgrounds behind tiles (in addition to the background through the tiles). I'm sure there are more than enough to make up the bullet points to fill a whole article.
  • I did a hard reset on the previous build before upgrading my L925 to the current build. No overheating issues so far. Stayed quite cool even during the long update.
  • Light theme is much better.
  • I'm currently downloading the update but, it is still in 4% in more than anh hour of downloading. any reason or help to address this issue? Does this update address the issue in outlook notification as email arrived? And does this included the word and excel preview?   Thanks in Advance.
  • Store is horrible to use. It took around 1 hour 30 min for installation to complete on my 520. Everything works good comparing previous build other than the store.
  • My downloading still at 4% over the last hours. any remedy or recommendations?   i'm using lumia 925 Philippines. Thanks in advance
  • I noticed all this on my own 1520 glad its not just me with the return of the forever on quiet hours
  • Updated my 640 from 10166 to 10512. Seems good so far. Just noticed an issue. Got it solved easily.
    Mine is dual sim and the problem is with the messaging app. Even if I open the second sim app it takes me to conversations of of 1st sim. The solution is to just link and unlink the tiles. This worked for me.
  • I like that this version doesn't pretend to have tethering, thus saving you time instead of wasting a frustrating few minutes before not working anyway. It's also nice that it includes win 10 wallpapers and stuff.
  • I would REALLY like to know has Microsoft FINALLY fixed the VPN client problem with L2TP technology. Windows Phone 8.1 Update1 phones does not work with ANY commercial/public L2TP VPN servers (e.g. Synology NAS VPN Server). Even with Desktop Windows User needs to tweak registry in order to make VPN connection work behind NAT.
  • All my issues are still there. Well after an hour with 10512, many are. Including the infinitely loading start screen, the camera crashing, after reframing with Lumia 1520 and returning to camera roll, it shows old image.
  • 1.Small things such as ability to set the bluetooth visibility,and editing the numbers for calling
    2.OTG and Wi-Fi direct
    3.multi windows feature
    4.Bring back the ability to download and app by PC and then install it to the phone!why this thing has been removed?!
    5. Web notation,extentions,and ask cortana for Edge browser.
    6.A better lock screen or at least some APIs for developers to create something! No new feature is really annoying!Even Microsoft doesn't say there are plans to add new features at least 5-6 new cool features not only and inly continuum!
  • Complain on the feedback app
  • I am also really worried about mobile os after they said it is feature complete. Hope MS will address these issues and introduce more and more APIs as well so that developers can make some cool stuff for eg. use of lock screen as you mentioned.
  • seems much faster and stable ! so far so good !
  • Installed it last night. I had the build 10166 and I had to hard reset it because it was very slow (only 22 tiles). So after hard reset... well it's a little faster than the last built but still far away from 8.1 I'm glad that they fixed the freezing after a call ends. That was annoying because I had to soft reset the phone every time it happened. Well there's a lot of work to do (I may even say huge). E-mail client is laggy, calendar is a disappointment compared to 8.1 version, the store is a mess, the lock screen doesn't have the option to update the background from the weather app, HERE Drive+ randomly stops to update the GPS coordinates, the gallery is laggy (image magnifying is laggy too).... I will use it as a main phone for daily use and I hope we will see new builds weekly.
  • Basic things missing.....ex: Glance screen, customize ringtone, notification tones, keypad sound disable, network selection 2G,3G & 4G.....etc....
  • I've had no of the known issues yet. But haven't tried the hotspot yet, so that's still a possibility. I'm a bit worried about the start screen to mess up in this build as it did in 10166 when I pinned all my Xbox games and put them in a folder. Got the Loading issue.
    Anyone knows if you could pin 140+ tiles w/o any issues? XD
  • Patience is rewarded. Better to wait for more stable builds.
  • can anyone say if there is now or will be gapless playback for music? that's make or break for me!
  • Still no 120fps :(
  • I don't have the new wallpapers under that date. Can they be found somewhere on the net?
  • Nice.
  • First, very nice reading. I have installed 10512 too and it works fine on my 1520 (non branded, carrier T-mobile in Germany). Yes of course the installation was pretty long, in the end succesful. Bad, the Hotspot bug, I have the lock screen information only for a split second delay on it before the user info or PIN are visible, so it just long enough to get an impression was is / was there. This was longer with 10166. The Store of course is in many ways a weak point. Overall I hope the builds show up quicker in the next weeks Regards Thomas  
  • Why is there still no custom keyboards, that's the single biggest compaint I alwaays hear. "The keyboard is hard to learn". Also personally I want smaller keys, showing more content and less travel distance between keys. Also, transfering established dictionaries and other personal typing traits from android/iOS to windows.
  • Wat abt Lumia 530 low storage device of 4gb
  • I did clean install on my L1520, all is except after entering my pin it goes in this long painful "loading" start screen mode. Same thing when I do Personalized Settings. Since I could not get to apps I end up using Cortana launch maps which interestingly worked well.
    Does anyone have similar issues or thoughts on possible fix assuming it is not one of the expected bugs.
  • I am unable to download update 10512, because I receive this: There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may heklp: (0x80244019). Any idea what to do? Thanks.
  • Does this build have an Outlook which allows to have a tile per email account (like 8.1 had)? Also, I really can not do without the Gestures Beta app. Read it is not ready yet for Win10 because Win10 misses some APIs. Hope it is added soon, or even better to the core OS.
  • I am unable to download update 10512, because I receive this: There were some problems installing updates, but we'll try again later.

  • Happened to me. My phone was not plugged in and battery was under 40 %. Posted via the Windows Central App for Android
  • Curiosity, what is so special about ios9? It looks to me to still have static grids. Very 2005. Siri is basic and the cameras, video quality etc are not the best. I feel ios is way behind.
  • Feels like a definite improvement for me over 10166. I've been running all TP builds on my daily driver with no catastrophic issues in the last few builds. Start menu is a big improvement and the folders look and function much better (have they also made all tiles crisper??). However, still some serious issues in order to win new users (admittedly, this is preview):
    - store and phone-only installs never completing/"change where you install apps";
    - camera - video capture, awful stuttering (deactivate video stabilisation to make usable); camera quality generally; Not experiencing quiet hours issues myself and this was a straight upgrade from 10166 (no reset). A great improvement so far... looking forward to more frequent builds. Fingers crossed the concept for start will be adopted, meta for media files added, wireless media sync and other refinements and bug fixes!!
  • I don't know what the two thousand problems fixed but still the OS is sluggish and lacks smoothness
  • In bad, you forgot to mention that "search" is still a f*cking WEB WRAPPER!
  • THIS IS A MUST ON WINDOWS 10 MOBILE Every Lumia user needs this, very convenient in a situation where you don’t want to make a separate contact profile. https://windowsphone.uservoice.com/forums/101801-feature-suggestions/suggestions/3195115-please-allow-custom-labels-for-phone-numbers-emai?tracking_code=1db4c0cbd29485ec7b2ca5d012152577
      Microsoft must concentrate on real issues that really benefit users rather than on small beneficial issues like wall papers that do not really make our life easier when using the phone.
  • What's that tracking code doing there?
  • The lock screen delay is REALLY annoying.
  • Is there still the Kids Corner in Windows 10 Mobile?
  • Of course!
  • Thanks, palmujukka! This is honestly one of the best features, if you have toddlers at home like I do! I wish there were a Kids Corner on my Windows (8.1/10) tablet as well.
  • Hm, The new glorious W10M that will lurk people over from Android/iOS has less features than WP8.1 (which lacks some of the features form WP7.x…) and is far from what you get on an Android/iPhone (except Livetiles that no one seems to ask for and maybe Continuum that has yet to prove that it adds anything usefull).   I don’t think Microsoft has to book too much manufacturing time for their phones…
  • Guys, I would like to seek for all of your advice, will be all our Internet Explorer bookmarks will transfer to Edge after we updated to Windows 10 Mobile?
  • Update wont delete your bookmarks app data will remain safe
  • W10M so far is great... If you desperately wanted a photo background behind the entire start screen rather than behind transpartent tiles alone. Or if you wanted to create entire and final documents in Word, Excel and Powerpoint on your mobile phone rather than on a PC. If you don't like to see this weeks appointments at a single glance, and you don't work with tasks. If you prefer to check your mail accounts separately. If you prefer multiple menu's in apps rather than a single one. If you prefer functionality that in real life might be very useful in several year's time (continuum) rather than functionality currently used every day (eg above). etc. etc. etc. If functionality in this build is what we're going to get in the end, I couldn't be more disappointed.
  • Still "Loading Scree" problem :(
  • I did not get the wallpapers or Easter egg on my upgrade. On 640 XL
  • first impressions wise this build was the worst. It looked like MS was not heading anywhere on mobile. Apps froze, phone heated up etc etc. After liek a dozen restart it finally started working like normal, but it still lags.
  • Anyone had it on their Lumia 535 yet? Any issues? Thanks
  • I did not do any hard reset, still impresive! unlike the previous build which amazingly broken without hard reset
  • Most of my purchase app not work
  • Hey Cortana :(
  • Can't even install build 10166... Phone always says something like charge battery to 40% to continue installation.
    I do a full charge, yet it says same thing. Help anyone?
    Using a Nokia Lumia 520 as my secondary phone. Posted via the Windows Central App for Android
  • after severall atempts it too 3 hours before i installed and had up and runing windows 10 mobile.  Tip dont touch the phone leave it 3 hours for it to istall all its own apps lol. Now i have played with it for a few gours mostly stable but thers 1 huge issue.  I cant log into my hotmail account.  I cant add my hotmail account to my email app lol gmail is fine but not hotmail, which is even funnyer as its microsofts own email lol. Im actually not bothered about this as the built in email system on my phone never lets me see all my emails in 1 inbox so haveing hotmail isnt gona kill me, it actually simplifys my phone life and need for a unified inbox.  Looks like ill stick with my gmail account then. Everythig is prety fast on my 930 includuing games.  all my apps work but i havent bough any yet with 10, ill waiit  till its released officially as i dont wana buy say tube casting only to find it doesnt get recorded as paid.   But if your prefared to wait the several hours it needs to install the 20+ inbuilt apps like setting and stuff then yeh its prety sweet.  But plse wait 2-3 hours or youll go mad.   I know this wait 2-3 hours is the same as the last 2 builds, it would be nice if you could have a warning on screen or on the tiles saying plse dont tougch let us install everything first. It would just be awareness that people like me like.
  • Although, Dan made mention that Edge (surprisingly) was running fairly well, does it pick up favorite's from 8.1 IE 11 mobile..? Does it have a 'Sync My Settings' feature? Thanks
  • Favourites aren't synced to the cloud. Not sure if it can import them from IE.
  • Hi palmujukka, hmmm thanks as I'll have to do more research on this. (FORUMS)
    As I just added a new folder in Edge Windows 10 Pro (laptop) and Windows Phone 8.1 Update 1 did sync properly and added it to IE ll mobile for testing purposes..would hate to lose all my mobile favorites, if I decide to make-the-jump to 10512!
  • It's doesn't keep message private on lockscreen build by build although I tried all ways. That's so bad 
  • just tried agian to add my hotmail accouint to my mail outlook app and it just keeps saying that the adress is already active.  Lol no idea why as im not logied in on it on my mail app.   My email is definatly not working.  My gmail is up and runing but not my microsoft hotlook email account as the phone wont let me put it on lol.  This is a fresh windows 10 install .  Tip dont touch your phone for 2-3 hours till its updated all its own apps.
  • The unlock delay was the thing that made me go back to Win 8.1 instanly on my 930. I really hope they fix that, also Store is almost unusable since it takes forever to do stuff.
  • Just wondering if you guys have problem checking in on fb app and using camera on whatsapp? Build 10512 on 1520, mine keeps on telling me to enable location (it's already on here drive is working), WhatsApp camera kicks me back to WhatsApp like nothing happens.
  • Yep.same here on 1520
  • Well my 1020 is worse on this build then the previous. Much slower and screen hardly responsive the notification bar takes several swipe's before it comes down.
  • I have Lumia 535.I updated it to build10166 about 2 weeks ago.today I check for update but it says your phone is updated.Tell me what I do.
  • Roll back to Windows Phone 8.1 using the Windows Phone Recovery Tool, then update to 10512. If possible, do a hard reset and don't restore from a backup. That ensures the best possible experience.
  • Bro download windows insider app register there and choose fast upgrade option from there youll be able to... No need to recover to 8.1
  • Thanks alot guys!!!!
  • I got no themes at all I wonder why Posted via the Windows Central App for Android
  • DON'T get a 435 to try out WM10. Fast ring updates cause bootloops and the slow ring updates appear to have been withdrawn. I want my lunch money back
  • After using the iPhone 6 Plus for a week, wp OS and their mobile product design team is crap. I'm glad I went to the dark side after years of resistance.
  • Anyone can confirm auto upload for images to one drive in this build?
  • Guys . I wanted to update to 10512 in fast ring . But I was wondering to wait for the slow ring.
    you know.. I need advice.
  • What happen with the ability to split the screen...they taking too long .. wake up Microsoft. .
  • It is nice knowing that a hard reset won't eliminate all of my saved pictures or notes or even my calendar since it is all in the cloud baby!!
  • I am sorry but what is changed?? Feels the same. Plus new bugs like WiFi sharing hotspot and quiet hour not working anymore. -2000 defect fixed LOL
  • Agreed and new things seem broken. Many apps won't launch at all now. Was hoping to make it my daily driver but not with this build.
  • My Lumia 635 got stuck on black screen that just said loading. Even after switching on/off, and soft reset. Had to do hard reset. The Store sometimes gets a bit stuck. Aside from that best build yet.
  • Nice this build fixed my missing apps list on my Lumia 920. I did not reset or anything before entering the Insider program and since first build the apps list have been missing.. after this latest build the app list is back :-) Finally I can re-pin Outlook to my start screen instead using search all the time :-)
  • Hey Cortana still not working on my lumia 930 people live tile still just dots no faces even after soft reset then hard reset
  • The only reason why I keep. My 1520 is because of its WiFi hotspot and now I can see in the last build the WiFi hotspot has issues and still hasn't been fixed, it's been a long time windows time to do smt Posted via the Windows Central App for Android
  • U can get the preview update for Lumia 1520 AT&T tru the Windows insider app, just tap the 2nd option and go to check for update at ur phone setting, it will b ready to downlaod
  • I'm aware but that is not my issue.
  • Why Cortana is not working on my L625.i m still on b10166.
  • Should i install this build on my primary device ( Lumia 630 ) ? Or should i wait for the official release ?
  • Do live tiles flop exactly like in Windows 10 pc in this build, or they spin the same as in Windows 8.1 phone?
  • Weathervoption doesnt work for lock screen ???
  • @wengWeng_21, download VLC media player and u will enjoy ur movie on the full screen
  • And hate that quiet hours lighten up for no reason...!!!
  • Returned back to W8.1. Sorry, but not working Mobile hotspost, we are returning back to old bugs. Not sutisfied.
  • Can I download 10512build from 8.1??any instructions need to follow??
  • Has anyone used Wi-Fi sense on their W10M phone with a W10 desktop yet? I haven't been able to get it work yet. Seems odd. Maybe I can't use Wi-Fi sense with my own phone when it is my desktop that knows the password?
  • It works nice but there are some fundamental things missing (again): - Universal folders in Mail (This is stupid and useless app without this) - Month view in Calendar (make it to be CALENDAR too, not planner only) - Glance Screen (Lumias has no LED notifications, so Glance Screen is must have)
  • Anyone notice background tasks of existing apps not running (that is, live tiles not updating) in WP10?
  • Not downloading update .. Stuck on 0% !!!??? ,
  • I am still having issues with music skipping a lot on my 830, so I am going to do a reset to see if that fixes the issue.  Plus, wallpapers :)
  • Yes you can download windows insider app register and choose fast upgrade option there you go
  • Done Hard Reset to get rid of slow downs. Overall looks good but it too early as apps breakdown after some use in previous build. Its really a battery eater on my 430.
  • Store is not opening!! :(
  • I am getting an error 0x80070003 while downloading the the 10512 update. What can I do now?
  • Will datasense be brought back to Windows 10 for mobile?
  • Its
  • Working great on my Lumia 640 no hard reset needs, thank god. Also this is my first trying W10 mobile preview on my phone, must say i am impressed. Microsoft has a bright future in the smartphone business!
  • Been using build 10166 as a daily driver for two weeks, updated to 10512 and its worse than previous build. Slow., lock screen doesn't appear fast, and no WiFi hotspot
  • Still have the start screen "Loading..." bug, witch is really anoying when you try to use the phone as daily driver and keep giving feedback.
  • This update is lot way better than the one i installed 5 months ago keeping the build number aside
  • In order for Windows on phones to succeed two things need to happen: first there has to be one or two killer, state of the art, cutting edge, above the competition, flagship phones released on all major carriers alongside Windows 10 Mobile this Fall. The hardware needs to be super on point and irresistible, from specs to design. People need to see these phones and say "omg I want that phone!". And second, the OS needs to have a few **unique** features that are no available on either iOS or Android. W10M needs a few things that people would love to have and use and that are **only** available on that OS and not the others. I know those thins sound a lot like wishful thinking, and frankly speaking Microsoft has a track record on not delivering on any of those things in the past, but if they want to succeed in the mobile space they gonna have to go above and beyond anything the competition is offering. Otherwise people will continue to ignore Windows on phones.
  • Hey Daniel, can we expect any new features in the upcoming builds? @Daniel Rubino
  • Hey Daniel, can we expect any new features in the upcoming builds? @Daniel Rubino
  • As Dan'l said, it seems more stable.  I had gone back to 8.1 (Denim) on my 925 from 10166.  Thought I would give new build a try.  Loaded 10166, hard reset, then loaded 10512.  Initial impressions:  Seems more stable; runs cooler; was a delay initially from lock screen, but seems to have resolved itself; initially Store would keep bouncing back but that seems to have resolved itself. These are just some initial observations.      
  • that wifi bug is very irritating, also outlook is too clumsy
  • Daniel, I updated by 535 to 10512 and reset as you adviced. Now it is all in chinese. How do i get it back to english?    
  • Running this new build on my 920 daily driver. No issues so far.
  • I downloaded it in my ATT 1520, but as usual I had to do a hard reset because it just sat on downloading for like 2 hours. Running fine so far, really haven't noticed anything that makes me want to do the happy dance, however in glad to be able to assign custom ringtones for contacts, actually that's one of the reasons I haven't used my 1520 as a daily driver, give this another few days to see how the battery reacts and possibly, I mean possibly it'll be my daily driver again. I can't wait till the new talkman and citiman are released. Dam I'll be in love with Lumia again....
  • I did a factory reset and it went straight to the latest build.  The only problem I had was that everything was in Thai, because I still have the SIM in it for my recent trip to Thailand.  Very fun trying to figure out how to add English and remove Thai when you understand NOTHING on the screen.
  • Blocking numbers still doesnt work :(
  • Edge has a few issues. Responsiveness & loading running clean install on L640
  • Awesome. It's gradually starting to look more and more like Windows 10!
  • I'm running this on the 1520. Anyone else notice that Hey Cortana isn't available? The previous update told me that it wasn't available for my device, when I tried to turn it on. With the newest update, the option to turn on Hey Cortana isn't even there.
  • I was in 166.. Straight away I instal d 512 without ne reset in my L730 n its much bettr dn d previous one.. Lock screen acts weird thou
  • I would appreciate an alternative to the square tiles. At the very least some rounded corners variation.
  • Rough experience with this build compared to the last. I installed on 1520, 820, and 635. General slowdown in all cases. The lock screen delay shows on all 3. The 1520 and 820 a have graphical glitch on the hamburger menus: When sliding in from the left, only a thin vertical line shows until the menu is fully extended...then the full menu will appear. I hard reset the 635, which does seem to help a bit. It's discouraging to see how far we are from a final build.
  • My 640 XL doesn't see the update too :(
  • Great article but the author needs to work on his grammar skills. So many missing words and sentence fragments.. Also on the 1520 do you have the insider app installed? I had removed it from a phone running 10166 and forgot about it until i tried to upgrade and couldnt see the update. After reinstalling the app i was able to upgrade.
  • hi! how are the lumia apps working on your icon, in mines, refocus, panorama,  beamer, storyteller, cinemagrapph,  video tuner, creative studio, moments... among others, many other that are lumia centric, are in the listo of not work in this device, so how are you seeing this, or is just me, because i update from 10166 to 10512 directly and no hard reset??
  • I've got to say, those home screens look like a mess. There's way too much going on, with the sheer number of icons, within tiles, sitting on top of a photo. It also annoys me that no we're stuck with this 3 column layout but can't make a tile wider than 2.
  • Mmmhmmm.. Store not working, people hub unstable... Back to hard reset with fingers crossed
  • Installed it on my Lumia 520-no cell service-wifi only Win10/WinPhone tester "spielzeug". Only got to spend a few minutes with it, so this is hardly definitive, but I didn't really notice anything different. I didn't notice any problems with the login screen, or the store on the one hand, but I also didn't notice anything meaningfully smoother or faster than I did on build 10166 on the other, which I thought was pretty smooth anyway - especially for such a wimp as the 520. If my daily phone were a Windows phone, I'd be able to immerse a lot better, and give better thoughts. Unfortunately, my daily phone is an Android (Galaxy Note 3) and my 520 gets very little use outside of right around build update times. Maybe I should just spring for a month's worth of prepaid talk time and data, forward my calls to whatever number the prepaid thingie gives me, shut off the Android, put it in a drawer somewhere and just force myself to use the Lumia daily for the month. That would give me a chance to immerse. Posted via the Windows Phone Central App for Android
  • This us,the 3rd build I have installed on my 1520. I highly recommend that after you do the upgrade, do a master reset. Do NOT restore from a backup just choose the new version. Yes you will have to install apps again but this way has always worked for me. Besides
  • I have upgraded my daily driver 1520 with all these windows 10 builds. I highly recommend that after the upgrade you do a master reset and do NOT choose from your backup. Just start new. Everytime it works good. I know you have to reinstall your apps but it is good practice on your phone. Side note they still didn't fix the screen issue when making a phone call. It's better but still blanks out.
  • New build is running fine on my Lumia 925... however, i still dont have the option to use custom ritngtones... Does anyone else have this problem????
  • Photes unable to send through skype and whatsapp. Videos creation is ok, but it has a bug when send pics or camera shots
  • I'm at the point where I'll either wait for the retail release or probably just get a new phone with it because the ATT 1520 for me has been a miserable experience with 10.  The phone already has numerous screen sensitivity issues and they seem to have been magnified when I tried out 10166.  I get that it's a beta and that's fine but it's pretty clear the 1520 for me is a phone best left in 8.1.  I'll wait for the 950 XL for a real top end replacement.
  • I have it on my 1520 and like the last build I have the most common problem reported on feedback. No start screen and just loading ...
  • No love to my 1520, I'm getting error 0x80244019
  • I glad to see all you folks with 1520's. I bought one specificlly to upgrage to Windows 10 and was dismayed that it was ot on Microsoft's list of inital phones. I complained to Microsoft Mobile and actually got 2 responses from them. They are actually listening which is great. It's also great to hear that you folks have installed this latest build on you 1520 and it seems to be working pretty good. I don't know that I'm ready to take the plung yet but keep the comments coming and just maybe I'll jump in on the next build. Glad I found this site.
  • On the newer devices it should just be a mini PC in your hands. All this phone stuff should be for 4.5" or lower. .. Just my two cents.. It's possible they just don't want to do it.. Maybe when more arm processors are in phones this will happen.
  • SMS notification is still a problem. The live tile is more like a dead tile for text messages.
  • My lock screen hangs for few sec untill the calendar shows info.... all the time in l525 .... Is anyone facing same prob ....!??
  • All abut high end devices wt abt low storage device abut Lumia 530
  • Build 10512 is faster on 512MB devices as well (Nokia Lumia 625). Yet to do a hard reset to experience the full performance.
  • Hey Daniel. You wrote about the "default tile setup", is that something you can turn on or just a feature you have after installing installing after resetting the device? It would be cool if you could actually turn it on/off manually. Nice article as always.
  • Article is spot on. The biggest improvement is Edge performance. It even handles windowscentral website well, and it is easily the busiest, worst site I visit regularly. C'mon guys, we know you need money but can't you get it without all of the ads flying all over the screen?
  • Shit is a mild word to describe this build.... 10166 was better... Even a naked running girl's boobs are stable compared to this build...
  • I'm using lumia 1320... and today i tried to install build 10512 but it does'nt finished installing, its stuck on 99% (I THINK) and not finishing installing , then i restarted my phone while it was installing,so after that when its open back its keep instaliing... dont know what to do... till now its 5+ hours its installing...
  • Thanks for the article Daniel. I thought it was just my Icon with the slow lock screen, but I'm glad to know its something Microsoft needs to work on. My Icon is actually working very well. I'm still pi55ed about the Photos app. It won't find any of the folders that I put on the phone from my PC. What's up with that? (I tweeted @GabeAul about it) I've had a couple of crashes here and there and a bit of trouble on downloading (prob due to that WiFi disconnect issue - although I think it might be "internet connection" altogether, because even my LTE connection isn't very solid). Thanks again for the article. If I find anything else on my Icon, I'll post or hit the "News tips."
  • Every time they release a new version, I install it. And every time, I'm disappointed. Windows 10 Mobile is a CATASTROPHE. It's dramatically inferior to Windows Phone 8.1, and less intuitive even than Windows Phone 7. Its performance chugs (Lumia 640) even after the much screeched about hard reset. The mail app is TERRIBLE. Pinned folders? Pointless, they don't open the folder, they open outlook to the last page that was open. They don't update their tiles. They don't even sync at all unless you manually go into each one and sync. So far, Windows Mobile 10 is a terrible operating system. In its quest to appease iPhone and Android users, Microsoft is destroying Windows Phone. If I wanted an iPhone, I'd buy an iPhone. I choose Windows Phone because it was different and offered things that the others don't. If that's no longer the case, then I'll just buy an iPhone, because at least I can count on Apple to deliver new high end hardware every single year on schedule.
  • 920's cpu still gets pretty hot, with no draining app running. That, imo, should be (have been) top priority from a core quality point of view. Not really worried about (killer) features. In terms of Sales; if MS is able to implement the Universal apps First-Time-Right, Business Sales might suprise us all. In the Netherlands, quite a few organizations adopted wp due to the Solid appa For Business (basically Office which is frickin' sweet now) and integrations with O365. The Consumer market will keep crying over the app ecosystem, even though the majority of users uses Mail, WhatsApp, banking, browsing and soms main News apps, which are all there. I stuck to wp because I simply feel that the UE can easily surpass iOS and Android. Both have big frustrations imo (can't customize a lot vs a big pile of do whatever you want mess). So easily moving apps towards W10 combined with a (again) First-Time-Right Experience should create a Solid base. Love W10M as of Day one, uses every Insider version as a daily driver (and kept smiling ;) )
  • Screencap wasn't working for me on 10166 (on my 830). I was able to capture the screen but then I couldn't find the screenshot images anywhere on the phone. Does anyone have the same issue with that build? And is it all good for this build? thanks! 
  • Calendar sucks a$$ Posted via the Windows Central App for Android
  • According to this thread, Edge on Wi dows 10 mobile does not sync favorites (yet) even though Windows 10 PC has a new Browser Sync settings feature:

    Oh well will patiently wait for the next Win 10 mobile build release!
  • Apologies for my ignorance but I have never noticed this with previous builds before. But when you power down your device it displays your calendar events for that day saying "don't forget ...." Instead of goodbye!
  • I have same problem in my lumia 535 ,what about hard reset , does it solve??
  • Will the Lumia 830 in Canada get Windows 10?
  • I have same problem in my lumia 535, what about hard reset? does it solve??
  • Using Htc One Verizon phone and Quiet hours also not working (blinking) but my major issue is with social media apps. The photo gallery will not open to allow photo uploads on to various social media apps Ex. Nearby Live,WhatsApp,Kik and Wechat..will work through internet versions of the apps but not through the apps themselves
  • @Daniel - yea while the lockscreen delay is a pain and is more noticable esp on lower end  devices.. you can actually still swipe up and you get the ability to key in your pin.. so you can get in just as quick... :) just stuff like time n notifications arent visible instantly...
  • also my battery is slightly better.. still nowhere close to 8.1.. i'm a heavy user (on background data / apps ).. and on 8.1 i'd have about 40% left by EoD (9-10pm).. till the last build my phone would die by 4-5pm.. right now its still too early but i've got about 60% left.. :) PS: i use a 930 Also - hard reset isnt an option for users like me, since my company uses Airwatch MDM to configure email.. and on W10, the chaining to outlook / workplace accounts doesnt occur (the account doesnt get added / configured) so everytime i did a reset, i had to revert back to 8.1, setup my mail and upgrade to 10...
  • My lumia 520 rebooted itself on gear screen while installing 10166 from 8.1 denim. Now its only showing Nokia Logo..same happened when i tried it on lumia 625.help me
  • I am very happy with this build because I consistently receive text message notifications on my Lumia Icon now.  With the last build, I had to constantly check my phone to see if I got a text message.  I would constantly miss text messages because I didn't check.
  • Installed on Lumia 520 the low end windows phone. Its Working surprisingly well. Animations are super smooth. Sometimes one or two seconds delay after clicking something. Email app opening smoothly but deleting, moving operations are not working perfectly. Every app have this problem, opening smoothly but inside operations are laggy.
  • I've updated to the new build, but at the end my phone just showed a sad face ":-(", just at this moment I discovered that Lumia 720's usb wasn't working. Resume: lost my phone. Nice...
  • I STILL have no idea why people have to keep mentioning that there is "NO SNAPCHAT" as if receiving unessecary temporary pics is a necessity. Plenty of other ways to send/recieve & #&%%* pics if that's required for you to enjoy your day!
  • My text issue still exists on this build.  I am using an ATT 830 and unless my phone screen is already on, I don't get notifications for any text received.  If the screen is already on, then it works fine but I downloaded the update last night after seeing that was supposedly fixed and I have gotten 5 texts this morning with no notification popup/vibration/sound.
  • Hello. 10166 and 10512 not have lumia apps that was before nokia maps, like lumia camera, lumia panorama, lumia refocus, ... Is there any way to get it on w10m? Or is only solution to go back to w8.1?  Also when i roll back from 10 to 8.1 i sing up with my microsoft acount and i get phone like its not mine. Some other man was loged in not me... and I get apps that i never use.,, .. like microsoft demo1, microsoft demo2, microsoft retail,.. Can someone please explain me what was that and where to get lumia camera? I use now HDR camera as it is my second favorit. My phone is 920.          
  • For those who still miss Glance options after updating/hard resetting ( without backup ) :
    - Go to the store
    - Download SysApp Pusher
    - Open the app > Scroll down until you find Glance Screen
    - Click on the app, it will redirect you to the store, wait some seconds and click OPEN, it will may say that you have to restart your phone : DO IT
    - Then open once again SysApp Pusher and scroll down to Glanc Screen, click on it, once again on the store click OPEN and here we are! Glance Screen Settings available! IT WORKED FOR ME, Lumia 925 Windows 10 Mobile Preview 10512. PS : sorry for my English, it isn't very good!
  • Bluetooth sharing with PC not supported
  • Is microsoft done with new features , or anything else is coming up ??
  • But the video hasn't been shot yet, has it?
  • Anyone face problem with rearranging tile? Some tile cannot unpin, lumia 720
  • I hv problem with tile rearranging.. Anyone? Its just me or not hhoho
  • I updated to the new build..but got nothing new except the change of upgrade nber...why??
  • I was able to Install on my 1520 device, the following are the issues detected; (i upgraded from 10166 to 10512) 1. My Apps won't lunch 2. The wifi won't lunch (stuck on Off). 3. Quiet hour keeps flashing on the action center  
  • Currently running build 10166. [L1520] [Truth be told i stopped using WP10 due to glitches in a much earlier build.] That being said; am enjoying WP in it's current form. Runs well with no major bugs obvious. Well done MS.    
  • Not sure if anybody commented on this, to many to go through, but you can turn Quiet Hours on and off in Cortana under Notebook.
  • Obviously MS doesn't care much about WP anymore.  I understand that. However, for loyal customers and testers, it's a disaster rolling out a new edition with a KNOWN issue that the start screen doesn't load! and the solution suggested is even more ironic. You can't keep resetting your phone every time u come across this "known" bug. How would anyone test a phone when most their time's spent resetting it?
  • I want bugs fixed. I cannot download speech languages so my French 640XL won't let me use Cortana. A deal breaker for me. Grrrr. And then it filled my 64GB sd card with 50GB of god knows what. It would not let me see what had happened. That is why I had to reset my phone. Got to 93% and crashed on restore so none of my apps loaded. All good until the bug reported by hundreds of people through feedback from the build two previous to this one regarding language packs for speech kicked in. I have a 640XL dual sim LTE and it will be one of the first to launch. They MUST sort that language issue as a priority. Otherwise it is a really nice build. Not I am going back to 8.1 until I am told why it filled my sd card with junk and still hasnot sorted out the language download issue.
  • I am fearful of putting this on my 1520 DD.. What features of the 1520 on 8.1 are missing in the windows 10 update?
  • New feature:
    Has anyone noticed that to turn off Wi-Fi two steps are not needed from quick actions. In quick action short cut Wi-Fi is toggling like mobile data short cut. Long press Wi-Fi to go to Wi-Fi setting. So much peace waiting for this feature from very long time though it is pretty obvious kind of feature.
    Future feature:
    While attaching photo in whatsapp still albums are not shown, that means to send screen shot taken a month back, i have to do huge laborious job to scroll down. I guess it will be fixed.
    Stupid Feature:
    Glance is just a dumb feature if u don’t have Amoled or OLED screens because only in these screens particular pixels(saves battery , that’s the crux) of the display are turned on to display req info but giving this feature to low lumia or ips lcd displays, it does gimmick by keeping all pixels in thick black and simply info in certain pixels creating illusion of glance but all pixels are used(no battery save, instead battery drain). This gimmick creates performance issue to my understanding as when turn on display it acts as if display is just turned on, creating shutter issue or battery issue.
    Dead Feature:
    One thing of win mobile os which i cannot trade of with any other OS is ability to play YouTube videos under lock screen (or turning display off) Last three years i am streaming loads of gb listening to great speaker other listening stuff. This feature is buried now. It’s a huge disappointment as that feature is main reason for my new lumia 640 over some android phone. I madly and badly want this feature! :(
  • Hi I have this version installed on my Nokia Lumia 1020. While using wintools I have observed that with no apps open, this build takes 1.1 G Of my 1. 9 G RAM. That is very high memory usgae and leading to lagging. Has anyone tried this on Lumia 1020. Can you please share performance review.          
  • I am using Nokia Lumia 920. So far the build is good but I have one major issue. I cannot connect to internet(browser/install app) via my celluar data plan. I always have to be on wifi, any thoughts ? 
  • well i kept wainting for that  video you mentioned!
  • I've installed Build 10512 on two separate Lumia 830's.  One has the Start Screen Bug and one does not.  If a phone has the start screen bug it is a lost cause and totally unuseable just as a test device...   The groove app is still incomplete, many universal app are still not in parity with their PC versions (Fitbit etc.).  There are some general twitches and glitches but it is a quantum leap from Build 10166.  Everyone needs to keep pushing for Windows 10 Mobile to move forward.  Without mobility, what exactly is the point of Windows 10?  Without mobility we could all be happy with Windows 7 as a purely desktop OS without Touch, Speech, Continuum, Modern/Metro, and the Windows Store.  Without mobility Windows 7 could continue on for another decade like XP and Microsoft would fade to irrelevance as emerging technologies pulled us away from our desktops over time.  Windows 10 is more than the desktop OS, it is a broad range of progressive building blocks enabling the Microsoft experience to be mobilized and current and future technologies to enable the experience.  Right now a premier mobility experience on Windows phones is the single most important turnaround Microsoft must accomplish.  They must put every available resource to task to accomplish it. It is the current building block to transition into the future.  Where would Apple be right now if the original iPod never transitioned from a non touch single purpose music player into fully functional touch based phones and tablets?  Microsoft was caught stagnating as mobility evolved at light speed.  Microsoft somehow adopted a philosophy that third party developers must come to them and provide them with content.  Hopefully all that has changed and we will now get a forwardly progressive innovative leadership philosophy that will bridge the lacking content chasm with engineering innovation and hard work to bridge the gap between service providers and bring the service content to enable premier Microsoft ecosystem experience.
  •   Please do confirm me , Is that the 'Lumia Camera'? Is the 'Lumia Camera' back? if its soo THANK GOD! my 1020 really needs it!! 
  • Still have tons of errors  1. Windows 10 mobile will crash when you switch from mobile network to wifi network back to mobile network 2. Apps store update have six apps never fixed 3. lock screen never dispay correction, clock and date sometimes disappear 
  • Finally jumped onto the Windows 10 Mobile preview bandwagon. Played around with Build 10166 not realizing there was newer build. Updating my Lumia 930 to 10512 now as I browse WPC. I found adding email accounts and other stuff like the settings menus  very confusing in 10. But once sorted out I like the GUI much better. One curious observation: I didn't see Cortana as an app in 10166. Should it have been there? I'm in Canada but I changed the phone region/language to US and still nada. Should I expect to see it in 10166 or do I have to do some mojo to get it?
