Developer enhancements update rolling out to Windows 10 Mobile preview users

Microsoft appears to be pushing out a small update to those who are currently using the Windows 10 Mobile preview. According to tips that we have received, the update brings along with it some developer enhancements, and that is all that comes noted. This is not a new build, it is the same build, just some enhancements for it.

Odds are that all of the changes take place behind the scenes on this one, so no need to go hunting around to try and find whatever is new. If you are on the Windows 10 Mobile preview, you can check for an update now. If you do happen to notice anything new, be sure to let us know in the comments below.

Thanks to everyone who sent this in!

Jared started off writing about mobile phones back when BlackBerry ruled the market, and Windows Mobile was kinda cool. Now, with a family, mortgage and other responsibilities he has no choice but to look for the best deals, and he's here to share them with you.

  • Hate when they don't publish a change log; is that really so much to ask?
  • No update..
  • It's probably not for every device.. My 1520 has nothing...
  • Could you please let me know what your experience is like running it on 1520? I have the same phone (my only phone) and I wonder if I should install it or not yet.
  • It's fine now.. Nevertheless, you're going to have to be able to put up with bugs, and some missing features.. But, if you could live with WP8.1, as far as features, then you will be fine.. You'll be fine because W10M has worlds more features than 8.1 already,, even with features still missing from 8.1...
    1.. OneNote: Still choppy, has trouble with C&P, but it's usable now.
    2.. The store: is still kinda a pain, but it's working now.. Updates are still iffy, and it's not really syncing to your account yet, so you're paying for everything, unless it's free.. (Music)
    3.. Groove: Oh, god. The concept of the app is solid, but, Lol bugs!... Black screens after lock, force closing after the last update, no music account recognition, so on..
    4.. Photos.. SMDH. Let's just pray that this isn't it. Lol. But, it's working now.
    5.. Random reboots: Which ironically are welcome!.. But, only because the OS isn't acceptably stable yet.. So, periodic reboots are welcome.
    6.. Cortana's not ready for primetime, and in my opinion.... She's not aged well. Kinda ugly, for now.
    ......
    Nevertheless, it's still a preview, and I would hate to go back to barbaric WP8.1, so that say's a lot.... The office apps alone are enough to upgrade now..
  • you got any issues with onedrive not backing up photos using the 1520 with WP10?
  • Mine works. Go to OneDrive Settings and turn on "camera upload".
  • IDK.. Let me check.. Have you?
  • i had this issue with my 930.. but it works now after a factory reset.
  • Do you have problem of freezing after call ends or anything after or within calls
  • i am also having same problem, have you fixed it?
  • I too am having some random issues with the phone app freezing. Visual voicemail does not work - does not play the message at all. Have to dial into voicemail # separately to get voicemail. Lumia 640.
  • Cowards live longer, with at most suffering, you've know all about the current build, at least you shouldn't be asking the same question,let alone having read the above article
  • My 1520 updated before this story was reported; O2 UK phone.
  • I got it on my 1520
  • :'(
  • Some people are just to lazy. As far as me, I like to publish as much information as I can for my app updates like what I've changed, what I've removed, and what I've added.
  • @Zack good point ... sometimes we developers make silly and obvious mistakes which we want to hide to avoid embarrasement :P 
  • This update is our sign that another build is about to hit.... Just an update for an update to work properly.
  • I installed the W10 SDK and Emulators last night. Emulator image is of build 10240. Let's hope this is coming shortly to phones!
  • Please drop a link for that. EDIT: Nevermind: https://cloud.mail.ru/public/G1Fp/5acuS8fAF
  • Is that for the SDK and the Emulator?
  • How's it looking so far?!?
  • If you put an App called Hardware Test, it has allsorts on it, one section called System Information / Phone Update, it tells you every update that goes on your phone how many Packets & every little detail, it's free Genuine & safe.
  • Cue the demands for a new build.
  • Cue the queue for the spellchecker.
  • U edit m8? Lol
  • Well then.
  • Hopefully a new build will be out in the next few days.
  • This, and tons of bug fixes
  • since this new build is taking so long to come i believe it will be close to perfetct:D or i wish ** :P
  • Nothing here
  • Just checked for the update. It says there's nothing new and I'm up to date.
  • Same :/
  • Same. (L635 build 10166) Arizona, US.
  • Something's better than nothing.
  • No update here in Germany on my Lumia 920.
  • Hook yourself up with a L930 than will you will get one ;)
  • Same, nothing here in Belgium on my Lumia 930
  • Up to date, nothing new here in india - Nokia Lumia 1320
  • Sheesh, how much is there to read on the update page? It's like a whole manual.
  • Nothing new here in Canada.
  • Interestingly Joe B just tweeted a photo of an unnamed phone running continuum to his dell monitor.
  • Yeah I saw that. He says it's an engineering sample with the necessary Qualcomm parts to test the feature.
  • Not unnamed but Xiaomi Mi4
  • No, his daily driver is the Xi4 on build 240. The continuum device was just a prototype shell with the necessary Qualcomm processor.
  • Nothing here too in the UK
  • Lumia 930 in the UK - update offered to me. I did not initiate checking for update.
  • I see the update. On my 928
  • had an update in uk lumia 925 i reset phone and it upgraded to a new version  
  • what you mean what version? or built, wich is the  difference?
  • Not on my 630
  • Lumia 530 ;(
  • Interesting on basemark Note software version lol http://web.basemark.com/
  • Hmm ?
  • That site thinks my 1520 is running Android 4.2.1, lol, wtf?
  • Nothing in uk
  • Nothing here in the Philippines, No new updates
  • Same here. .what phone r u using?
  • How are the builds recently for the Windows 10 phones?  I only use my phone for music right now (i have a second phone) so i was thinking of upgrading to the preview.  Worth it?
  • Yea man. Do it. Second phone? Nothing to worry about. I'm using it on my daily driver. Having said that, to avoid the hassles of another install, hold off for now. Another update should be out within a week or so (I hope).
  • It seems pretty much hit or miss. I have almost no issues on my Lumia 930, but i have seen a ton of people which do have issues. So i guess it depends on things like 'do you clean install it' and maybe app usage.
  • Tons of issues on my 928.
  • Edge is essentially unusable on my Lumia 635.  Outlook crashes pretty often.  Calling and messaging I've had no issues with.
  • Do a hard reset! Having some of the same issues after installing but the hard reset fixed most of these issues.
  • Downloading now. As always thanks for the tip windows central and everyone else who tipped windows central :)

  • How do you know that? Can you be more specific? :)
  • Nothing here on my lumia 1520
  • Update received @ 20:00, London UK. Lumia 930. Installed. No issues. No noticeable changes.
  • why there is no release of technical peview for HTC WP 8X...?? Will It get the support from microsoft
  • The same reason there isn't one yet for the Ativ S and Neo, old phones that Microsoft don't own get support last.
  • Downloading the update on my Lumia 730...India
  • nothing for me....am also using 730
  • Even I got this on my HTC 8X month ago...but no build..
  • ? It's just been released
  • Here's a screenshot when I tweeted this to Gabe Aul, he didn't respond anything. http://1drv.ms/1IuVYqz You can see date when it was tweeted.
  • Yea, that's not Windows 10
  • Nothing so for for my 640 LTE.
  • 1520 32 GB here, I'm getting it . I hope it allows us to log into the Live Microsoft Account. The Preview only accepts " LOCAL" . This does not allow us to sync FAVORITES with our PC,s/ Lap Tops   Also HEY CORTANA" ..would be nice to use . I forgot how nice it was until downloading Windows 10 Can anyone else log into your main Account in Settings ( Mobile Preview) ?    
  • Don't know IF it has something to do with it but after the Update the Store UI changed a bit!!!!
    The whole build runs more fluid and when i opened an MSN App there was this Info stating that some Apps (for e.g. Health & Fitness) are being shut down at a future time
  • I was getting this update every time I tried to update my Lumia 435 (test device for apps etc) from 8.1 and it failed every time. I didn't get it when I updated my Lumia 1020 from 8.1 and that worked fine. Never did find out why it was being picked up by one phone and not the other. This was back when the latest build first came out. Not sure if it was the cause of the upgrade woes.
  • nothing here lumia 1020 mexico,   if i  return to  8.1 and reinstall w10 will i get  this new fix built? regards  
  • Probably an update only going to devices MS mentioned were headed to Windows 10. My 1520 as it turns out, didn't make the cut.
  • Except for the whole fact that my 1020 is receiving it :). My theory is this is only going out to those phones that have developer (side load apps?) option turned on.
  • Hi! I believe u must be correct. I have a 535 and a 1520 and none of them received this update so far. The article mentions that the update is related to developers, so, the update must be dropping only on phones with the developer tools enabled, which both my phones haven't...
  • I received the update in L920. No developer options turned on! :) 
  • I do not have the 'For Developers' setting on. I got the update.
  • Got it on my 1520.
  • No update yet
  • Hey is anyone else getting problems trying to download apps
  • I really like that you can pin phone update to your homescreen in win10 mobile. Makes it easy to check for updates...
  • you have to be already in developer mode to recieve the update.    here's a link for more info http://wmpoweruser.com/windows-10-mobile-receives-new-developer-enhancem...
  • I hadn't enabled developer mode if i recall correctly and I still got the update (L920)
  • interesting.....notice anything since the update?
  • Seems faster
  • I was able to download the update on my L730 without enabling the developer mode..
  • L1520-NewZealand just updated!
  • No update here in eygpt on my Lumia 535
  • does it work smooth on your lumia 535 ??? any lag
  • does it work on your lumia 535 .. any lag or crash issues
  • No update 820
  • Installing at the moment - 925/Voda UK. Will be interesting to see what may have changed.
  • Got the update 1520 Finland. I got lots of apps that I cant open. It began with all apps but now my phone is coming to life but there are 10-20 apps that i cant open
  • No need to get this update if your not in developer mode. I do need a new build. C'mon Microsoft
  • Lumia 925, mission accomplished, one of the fastest updates so far without data migration?!
  • This is just some background tweaking. There was no new build, so don't let the speed fool you.
  • Yeah I know, just telling it was surprisingly fast update :)
  • There are issues with the current build though I am still using it on my daily driver. Once I get my kid off of it I can grab this Dev update as I sense that a new build is imminent. Updated this morning on my 920.I look completely spastic, as I just got back from a trip to the US, right over the release dates (of course). So I have my Lenovo Tab 8 in forced update now rebooting, my 920 updated for the Dev bits, and my PC and Acer tablet all nicely tucked into Windows 10. Life is good here...Lenovo at 30%, Installing!
  • Nokia 925 in UK.  Suddenly Cortana now works, Still on 10166. ver is 3051.50009.1451.1006 but i can't say if that has changed.  Notification drops down to say Update installed.  Have'nt had that before.  My Outlook mail and calendar apps reported an error and there was an option to auto fix.  Not seen that before. Some of the waiting dots ......... now loop as in PC version instead of moving across screen from right to left.  I don't believe I had Developers Mode on, however,  I have previously downloaded the Mobile SDK to my laptop. This was not a small behind the scenes update, as it went through the whole installation process and took as long as a build update.          
  • Can someone tell me if it's okay to install the win 10 on lumia 535 since its my daily driver ...
  • The experience will be better in some respects as compared to 8.1 and worse in other respects. If you can't handle the OS crashing on you, I wouldn't recommned installing it. Also, I would suggest waiting for the next build in the fast ring that is just around the corner (possibly next week). This way, you will save youself the two time update and experience a better build immediatly.
  • Thnx for your reply I will better wait for next build
  • I've been checking all day for updates none yet. USA . . October 4, 2015 is my guess for release date of Windows 10 mobile..
  • Why so precise?
  • Because that is a tuesday. It is unlikely that it will be tomorrow as they are still testing and it would be so close to Windows 10 dekstop release. Also, they don't usually release things on monday. So, the next guess is tuesday :)
  • Will HTC 8x get it
  • no update istanbul
  • US AT&T Lumia 920 here. Update is installing now :) 
  • No update on the 930 :/

  • My Lumia 930 says, "Your device is up to date." Dubai, UAE.
  • .
  • Now when I go to Settings > Update & security > For developers it crashes back to the Start screen and my Action Center buttons blink. Other than that, I haven't noticed anything obviously new on my 1520.
  • That happened for me before this update too.  Once I enabled developer mode in that menu, every subsequent time I tried to go into the menu it crashed.
  • When I go to settings >update & security >For developers it crashes back to the start screen and action centre icon blinks continues
  • Anyone know of a fix for this? I've just updated to the Windows 10 Beta, and it's started happening to me...

  • Hello... Will the windows insider will voids the warranty of the mobile.
  • I am running internal builds on my daily lumia 1520. The builds are updated daily. It seems the mobile build is locked down to 10.0.10240.xxxx. I get daily updates. Only the revision number is updated. So it could be that the mobile OS is ready for release. Having said that, there aren't any drastic new features in the latest build compared to 10166, which is sad. On the positive side, the system is lot smoother and stable. Hey Cortana and glance are still missing.
