'Critical update' available for those in the Windows Phone Preview for Developers program

There's a new update out for those enrolled in the Windows Phone 8.1 Preview for Developers program. Go to your settings and check for an update, and you'll find 8.10.14192.280 available. The download and installation of the update should take about 5 to 10 minutes. Microsoft is listing this as a 'critical update'. Don't skip out.

Want the update if you're in the Preview for Developers program? Just go to settings -> phone update -> check for update and your Windows Phone will hit up the servers and grab the new update.

We're not exactly sure what Microsoft means by 'critical' in this instance, but we'll reach out and find more.

We're updating right now, so we can't comment on what's new or fixed. We'll let you know after installing if we find anything. If you beat us to the installation of this critical update, let us know what you find!

Update: So you want to know what 'critical update' means? Here's what Microsoft has said (opens in new tab) about today's update:

"This update contains our usual scope of fixes and improvements. We're requiring this update so we can continue to test our update systems. The update will show as a "critical update" on your phone."

Thanks for the tips everyone!

  • Seems faster.
  • Oh yeah!
  • Seriously it really is faster. Less resuming time and quicker animations
  • Yup man you're right
  • +1020 and 822
  • I log in just to downvote you :D
  • Me too
  • This has to be implemented in mobile app XD
  • Thanks, appreciate it lol
  • Seems critical.
  • Lol, you won 3 internets with that one
  • I hope you think faster and more to comment something better. Shame
  • +925
  • About time for another Daniel posting etiquette article :)
  • Oh yeah!
  • Hahaha, I don't remember the first one!
  • I think the phone definitely seems faster. The start screen tiles take lesser time to render when you scroll down real quick, the apps are resuming faster than before. Not a bad update.
  • In all seriousness, I do feel like I can notice a performance improvement with this update on my 521. So far not getting quite as many "Resuming..." and "Loading..." lags. Might just be the full restart that helped, though.
  • Nothing seems faster in using 520 and even after the update WATSapp still takes an hour to open so does FB messanger and everything is all same (slow)
  • an update doesnt magically give your 520 a qualcomm 805 doesnt it?
  • That's like saying my Ford Fiesta isn't going any faster because I put new tyres on it. You buy crap, you get crap.
  • Well, really depends on what tires you put on it and which trim level and road conditions...I mean, a Fiesta ST might benefit from better than the supplied tires in warm dry weather, to a point. 
  • LOL
  • I thought this new comment system was supposed to block dumb comments like this
  • It does seems have a faster animation
  • Nice pun mate, nice pun.
  • Batter drain seems slower.
  • Same here and it also stopped the popping headphone audio on my ATIV S
  • So basically we need this update in order to get the future DP updates right?!
  • critical normally means some kind of bug fix or security fix.
  • Hasn't come up with any updates. Downloads aren't set to automatic and checked yesterday too. Do I have to wait on Verizon too for this update? Lumia icon, unlocked in the UK on tmobile SIM.
  • Are you on Preview for Developers? If not, then don't expect the update.
  • Yea that's the thing I've been on dp for a year or so. Downloaded thing thing, checked the box and all that.
  • My mom has nokia Lumia 720 and she doesn't have Developers Preview and phone askedhew for a critical update... we started to update and it is not still done and we started 2 hours ago!
  • no, this is DP so you shouldn't need to wait on the carrier
  • It fixed my firmware from Denim to Black, oh yeah, I'm on Verizon.
  • How did you get Denim on a Verizon phone?  Gotta be sarcasm, right?
  • Thats the thing, I didnt. The latest extras + info update falsely show Denim as current firmware.
     and yes whenever i type Verizon in a sentence sarcsm is applied.    
  • Uh oh... updating now
  • Smt another update? Were is the Denim update with the Lumia Camera update?
  • You have to get that through the carrier because carriers have invested sooooo much in Windows phone, that they deserve to dip their hands in it first. Duh.
  • Curse them, we hates them!
  • It's ours it is and we wants it!
  • Our precioussssssss.
  • Don't see any of them pushing WP8.1 update one and two in the next two months before the year is up.My moms 521 is still on WP8.The Carriers are putting the squeeze on WP.It's all about testing and pushing updates for Android and IOS.WP is nothing more than a third option like Blackberry was for the Carriers.
  • just out her on developer preview, she will thank you for it! It's not quite like dos to windows by there is a big difference.
  • And what about OEMs? the rest of the World is not locked in the carriers racket as in the US..... My Lumia 920 is Unbranded therefore I just need to have my OEM pushing it. MS where art thou?????
  • Yeah its sad asia pacific is 100% cyan Europe is like 98% yet N america cannot seem to do a simple test.... May be you should all call the carriers and ask them to employ some 3rd world telco workers who are experienced in doing this,,, Africa is 96% complete for gods sake. Go in the stores(and sites) and mock the shyt out of them they deserve it.
  • This is because the USA is now a dinky little backwater market. What you call "carriers" there, none of them are even in the top 20 in the world.  Several foreign carriers have invested into the USA but all the US carriers are miniscule by comparison - including AT&T who invented the technology.  These are the same clowns who totally missed out on GSM when the rest of the world standardised, consolidated and moved ahead.
  • All they seem to be interested is exclusive deals. Innovation is gone.
  • Do your mom some good and install her developer preview and then update her phone! What good are you if not even for such simple tasks? You don't even take out the garbage anymore 'cause you think girls will think less of you! Come on man!
  • Can't find your precious, huh?
  • hahaha
  • Excuse my ignorance, but what does SMT mean? I had assumed a typo of SMH until recently, and a quick web search doesn't have anything likely ...
  • SMT= Something SMh= Somehow
  • #troll ^
  • I thought SMH was Shake My Head?? Am i the one who's wrong?
  • Cool, thanks for the clarification. I was assuming it was an acronym.
  • Also SMS = Shake My Spear.
  • Yea were is that
  • It appears to be faster in some ways.
  • LOLOL
  • It appears that you are saying"seems faster" in another way :p /s
  • LOL!! Although I do hope he means that.
  • Haters gonna hate I guess :(
  • My phone is always faster after OS updates. I wonder if it constitutes a hard reset.
  • I agree. It appears to be not as slow in some ways.
  • Was really hoping that this was the late October update that Verizon was releasing for the 8x.
  • Me too :(
  • Verizon users need to form a support group. Lol
  • ^this. <self> Hi, I'm TRON, and I am a Verizon user. <crowd> Hi, TRON. <self> It all began when the Motorola Razor came out, I didn't know getting that phone and sticking with Verizon would be the worst mistake for me as a human being. I mean first it was calls socially, then smart phones came out and before I knew it I had a great phone that was never ever supported. I don't know how it came to this. The Updates never came despite everyone around getting them *sobs*
  • Install DP and forget about verizon. On my 8x it works fine since April 15th and I get all updates (nearly) on time.
  • I have DP installed but VZW and HTC are supposed to release a firmware update before end of month. Not holding my breath. I couldn't manage without DP installed
  • http://answers.microsoft.com/en-us/winphone/forum/wpdp-wpupdate/why-am-i...   Here is the info about the update.
  • Thanks. Will add above.
  • So for those unwilling to actually read the writeup, it's not actually critical, but rather it's a set of normal fixes, but it is being categorized as critical in order to test their update systems.
  • They're not simply testing their update system. It's marked "critical" because if you don't have it you won't be able to get the bigger, better updates that are to come.
  • Please read what I wrote again. You completely misunderstood. And if you still don't believe me, then feel free to read what Microsoft posted about it at the link above.
  • You can't really skip out, it will be installed automatically on Monday if you don't install it before
  • i got really excited when i saw it and checked to see if you guys had posted an article. a lot less excited now that i know that it isn't the official 8.1 update with cyan for my T Mobile Lumia 925
  • Just do the developer preview t mobile doesn't support Windows Phone
  • If he got the update then doesn't it follow that he already has the dev preview?
  • Seems mysterious
  • Maybe he does have WP 8.1 but he wants cyan that has more features
  • Cyan is a battery drain.
  • Agreed
  • I have been so used to the Win 10 update news that when I first read this I thought "what again" then it dawned on me this is for the phone. Downloading now.
  • LOL! Happened also with me...
  • Cool
  • Is most likely a fix for when we start getting denim,
  • The dream is alive!
  • Updating....
  • Installing /w/p
  • This indicates that Microsoft is trying to Avoid The cyan prob. of Bitlocker again .. 'AM I right ??   
  • that was a firmware issue.... the o nly way to test that would be with firmware....
  • yeah ..but this may be an internal Id code system testing the susceptibility of upcoming updates ;) 
  • Microsoft has said this is an ordinary update, the Critical status being a test.
  • Under-any cercumstances Updates are always Good .. :D except for things we dnt need to remeber xD
  • Yeh, plz give me cyan firmware on icon so I can test.
  • Sooner Or later ... !!! Depending how many years of your life left !! xDD
  • Downloading :)
  • I guess it'll remove name of nokia in extras+info
  • They Can do that by Simply Updating the Extras+info app... OS update isnt necessary for rebranding
  • it was just an idea. or they preparing for denim preview
  • Thats a good possibility.!! Fingers crossed :D
  • I'm waiting for monday because of update description :D
  • But it's sad still that those of us with htc 8x still don't have Cortana in some parts of Europe (Sweden)
  • I'm using cortana in Pakistan. I have htc 8X, TMobile version. Cortana is working perfectly.
  • Bro Pakistan Isnt in Europe I Suppose
  • Thanks for the bunch of loaded Info bro, i was reffering to the fact that cortana was firstly not working out of US. Now the UK versions are having cortana running perfectly so the european models should also have it. Cortana is now out of US.
  • Yep, I have an unlocked 8X here in NZ, just loaded this last update, all working well. Have had Cortana working perfect for the past two months..
  • NOBODY in the US with an 8X has it ...
  • Speak for yourself...I've had Cortanan from day one when I loaded DP on my 8X....btw living in Arizona.
  • I was referring to non-DIY'ers.
  • I hope it fixes the battery drain.
  • That's what I am hoping too!
  • +520
  • Tell me about it. I have to charge my 925 at least 2x a day! And it isn't even six months old.
  • You may want to try one cycle of letting the battery drain completely, followed by full recharge before unplugging from the charger.
  • Sometimes my battery saver shows the Phone usage bar extremely long. What's up with that? Has anyone experienced that?
  • +1020
  • +520. WhatsApp is a hungry dog xD
  • Mines is draining faster than ever now.
  • This update improved my HTC 8X battery life by 25%.
  • Mmmm... Do we smell preparations for the next update?
  • Anybody has finished downloading and installing it?
  • Too bad i am currently on my 3G connection :(
  • I think the next MAJOR update is near :D
  • Let's hope so!
  • let's hope resuming bug goes
  • Nothing,no cyan,no this update.f...k micorsoft
  • Oh wow, you sound so mature. Cursing a company for a feature that you don't have, that wouldn't even exist without them. You'll get the freaking update, just calm your horses. I swear, some of you act so entitled. It's a phone.
  • Dude hey right ! The New update dubian ( or whatever it) is called is lunching next month even there are phone users which doesn't even have 8.1 yet or the cyan update ! That's Microsoft fault ...
  • That's not Microsofts fault, go blaim carriers.
  • And who is that gave the carriers such power?.....
  • Thats your carriers fault.
  • Microsoft doesn't hold updates back, carriers do.
  • Lol... I read your comment and instantly thought of the Goldie Lookin Chain song... Guns don't kill people, rappers do! :D
  • Except in the case of Preview, where Microsoft did not release Cyan for 925 on TMobile US. Still waiting for Microsoft to unlock that particular combination, not that TMoUS doesn't have some kind of contractual interference involved...
  • Actually it's not Microsoft at fault here. It's the carriers but they play at people blaming the company behind it not them to get people to switch to iOS/Android so they don't have to stock WP anymore.
  • CARRIERS, Get it tattoed on your forehead. Why do you think everyone keeps banging in about developer preview??? So you're not held back by the carriers! If you cant help yourself why blame Microsoft??
  • Then again, Apple has figured out how to bypass carriers... MSFT, has not.
  • It's about the market share. When it's as big as Apple's than you have the power to change it. Otherwise you haven't.
  • You don't get firmware (aka Cyan) if you are on Verizon apparently, so just having the developer preview isn't enough.  I have it and have issues with the phone waking and wifi not working at times.
  • Same with TMoUS. No Cyan, despite getting all other Preview updates, including the one mentioned in this article.
  • Just got the notification about 10 minutes ago, updating now.
  • my 920 with DP 8.1.1 cyan has been incredibly laggy lately, for no reasons. startscreen is super laggy when scrolling, tiles are sometimes vlank and loads after a few seconds, typing texts is a pain due to the slowlyness. hope that update fixes it.
  • +920
  • looks like i can't edit my post so i'm going to reply to myself. yes, the update did fix some of the lags. my start screen is smoother now. still noticed a little stutter here and there but nothing compare to the lags i experienced lately. all in all, good update, for me at least.
  • Does your storage happen to be almost full? Because that can cause the phone to become a bit laggy actually. My 920 also had blank tiles sometimes but no lag.
  • In that particular case, the storage is not to blame, well I guess... I have a 32go 920. I currently have 18go free... my system folder is only 2,1go, I have installed 3,2go of apps and 6,2go of misc files (mainly mp3)  
  • This is good to hear. I've had the same issues with my 920 - been driving me crazy. Going to update.
  • I had that on my 920, but it didnt have cyan. the moment i got cyan (and, i assume, the correct drivers for 8.1 with it) my phone started running smoothly and i NEVER got that blank tile issue. are you sure you're on cyan ?
  • Updating
  • Just checked for update and I was advised I'm current! wOOt
  • You have probably unchecked the Preview for Developers checkbox.
  • Well at least installing it rapes my battery ! :(((( how is that eben possible
  • Restart your phone. That often stops the drain and then reports accurate battery status.
  • Killing mine too
  • Oh Nooo...
  • I'm posting a comment here, installing a 100 Mb app, and updating. I live dangerously.
  • I don't see an update. I'm getting up to date..
  • You need Preview for Developers enabled
  • I do..
  • Woops, good call. I did a clean install a few weeks ago! I didn't have it logged in! Cheers
  • Great. Enjoy
  • Just finished downloading it on the 925, will check it out to see what, if anything is different. Really would be nice if it fixed the battery drain issue.
  • In preparation for Denim? Hmmm.
  • false alarm...
  • Step towards regular updates along the line of Windows 10
  • +1520.
  • What's the download size? Anyone measured? Cuz I didn't XD
  • Give me a second, let me go get my tape.
  • It said 22mb when I updated a couple minutes ago...
  • 22/23mb
  • 24MB
  • 23MB
  • Updating now...
  • I hope it doesn't mess because my Icon is working incredible smooth and well. I love it!!!
  • Hmmmmm, slow unlock / terrible BT / wifi still crap
  • Lets hope the battery drain issue is fixed. I am tired of having to keep my phone hooked to the charger.
  • My battery app says it's chewing through about 14% per hour. Was around 4.5% before the update
  • It's alot foe a critical update... I bet it's more or less a prep foe another major update.
  • Let's hope that "continue to test our update systems" means "figure out how to deliver firmware via Preview for Developers"!!! There I go, dreaming again...
  • Just did it
  • Yeah, I was so hoping it was Cyan for my Icon. Why do the phones I pick (Lumia 822 and Icon) get retired so early?
  • hope is battery fix, that all im asking!!
    battery is crazy with the estimate, i take out from charger, saying i have 1day, after two times looking at battery, it shows 23hrs left! :/
  • If they allowed battery to charge whilst off, I would ge happy. If you full charge, then reset phone you lose about 5% charge.
  • oh! Is new update solved my bug with error 80188309. Updated my lumia 1520 
  • Now I've even got Lumia cyan...i was like:"WTF!? Hell yeah! But..." So, okay and thanks
  • The connection logo now says the data transfer state?
  • Where is that
  • Check your WiFi logo (if you are in WiFi connection) and there displays an arrow i think the data transfer state
  • That came out with Cyan.
  • It's not a Cyan feature, it's available in Black as well. Might have been after the initial Black update though.
  • Depends on your carrier. Att took out the arrows and data sense in black and didn't get it till 8.1. I have an att phone on tmo and I hated it.
  • It's done that for a few months.
  • I thought I was finally getting Cyan for my 928
  • downloading >>>>>>>>>>>>>>>>
  • Looks as if you are downloading while playing archery :p
  • Fb beta now wont stop installing :( going to uninstall and try again.
  • See anything new guys?
  • Downloading +920 
  • Done not noticed any changes as of yet though
  • Updated. Working good. Can't see any changes.
  • Nothing I can see. I wish they would allow backups to store more than 1 of them.
  • Maybe this will get rid of my pesky random reboots 1520
  • Maybe this will fix the bluetooth issues with navigation etc.?
  • I think Microsoft could stand to be a little more conservative with their time estimates for some devices.  The update itself took 20 minutes and it's been installing apps for the past 40.
  • Updated.. So I'm apparently patched against whatever it is was so critical. Funny though, evry update Microsoft says it'll take 5-10 minutes. When in reality is more like 30 minutes..
  • I can tell it smooths things out. My 1020 had been laggy for a couple of weeks and I was about to hard reset it (although I did that not so long ago). With this update it went back to normal
  • Talked to Nokia today, the Icon and all other Nokia Verizon Wireless phone will not be getting the Cyan update and because of some contract deal Nokia cannot supply the phones with Cyan unless Verizon wants it done. Can't wait till March when I can dump Verizon and take my Icon elseware.
  • What does "talked to Nokia" mean in this case?
  • I called Nokia to complain that the phone I bought in February isn't being support anymore ( and retired) and as a consumer I deserve better customer service than that. I hope a class action suit is started soon.
  • Changing carriers will not get you Cyan unless Verizon releases it. Updates are still tied to the original carrier unless you flash a firmware for a different carrier. I am so glad I spent the extra and bought my 1520 unbranded and unlocked.
  • I think he means changing carriers and getting a phone with the respective carrier.
  • I'm releasing 1st Jailbreak for the Lumia Devices soon.
  • and i'm founding a tech company right now that will become bigger than apple + ms in one day!
  • Cool story
  • Sounds like an Indian troll
  • It would be brilliant if it addressed the screen issue on the 1520's...... But I've all but given up on this ever happening.....
  • Yeah, kinda sucks when I'm stalking someone's instagram and I accidentally like their post. Hate it when that happens.
  • Haha I've sent an accidental friend request on Facebook that way (it was on my Lumia 900 though).
  • It's a well known hardware problem, pretty easy to fix though
  • Just installed the update on my 1520...looks like I can see improvements on the screen/touch issue. Will see how it plays up in the next minutes/hours/days....
  • I didn't have that issue on my 1520. Hopefully it will fix it for you.
  • This update made my 920 more redder....
  • what colour 920 did you buy originally?
  • Red.
  • This may have been a minor update labeled as critical, but why does it still not include support for the light theme in the store and in the photo's app? Surely it cant be that hard to add this small change into a small/minor update. Am I wrong in thinking that consitency in the OS is a resonable expectation  
  • You're probably right, but I have no knowledge of the actual difficulty of this. You should make a competing company and show them how it's done.
  • I'm glad they have this infrastructure in place in case any truly critical and/or catastrophic bug/exploit is discovered. I'm also glad they're testing said infrastructure, because while I hope they never need to use it for reals: You don't want to wait until you need something to find out it's broken. Also concern is how this is only for PFD, which suggests carriers could potentially hold back any real, legitimate updates tagged as "critical."
  • Maybe they are shortly releasing Denim update and don't want to mess it like Cyan, were the DP users did not get it due to bit locker issue. And this update might be necessary for smooth update. Again its just assumptions. :-)
  • Maybe an update to facilitate an update (or even non-beta version) of Live Lockscreen...?
  • I don't see the update
  • your Kung-Fu isn't strong enough!
  • It says there was an issue with a server or your internet connection during the update. Error 80072ee2
  • Ok Just did on my 930
  • Sd card is crazy
  • Hasn't come up with any new updates. Do I have to wait on Verizon for this too. Lumia icon unlocked in UK on tmobile SIM.
  • Make sure PFD is properly setup. This one has nothing to do with Verizon if you are properly setup.
  • There's not a lot to set up, you check the box and you're done ?!
  • Updated on my 925.  It's pretty laggy now.  When I scroll up and down on my home screen, it takes a second for the tiles to update.... grrrr.
  • Try Restart
  • Deleted some files from memory -- that seemed to help!
  • Mines always has been laggy on my 925.
  • This might be because several apps are reinstalling, give it some time!
  • Downloading on my 1520....
  • Lumia 830 Denim + Preview, got it.
  • In my Lumia 520 the update just free almost 200mb of storage
  • Is Microsoft still allowing the preview 8.1 for new Lumia icon owners? My friend is picking up an icon this weekend.
  • Preview can be installed on any WP afaik.
  • Not all, I tried installing on my friends HTC 8xt and it didn't install 8.1.
  • It works and it is damn nice. Not Cyan or Denim nice, but nice.
  • I do like the install by date.
  • I've updated it on a 1520 and a 625 - restart the devices to get everything to settle down, lag seems to go!!!
  • ALL my apps uninstalled after the update, now they are automatically redownloading. Every. Single. One. If I lose my Terraria saves, I'm gonna go crazy :/
  • Just wait for it to finish refreshing all... about 20mins, nothing will be lost
  • Last update removed several apps. Filmon.tv, metrotalk to name a couple
  • Boot up time has been halved. Lumia 930.
  • Ditto. 820.
  • Yeah I noticed that too. Phone restarts really quickly now.
  • The update features the word CRITICAL' nothing else... Thus making our Windows Phone experience better
  • Not showing on 1520 Au.
  • Make sure you have DP enabled, I have it on my 1520 and I'm in Aus. :)
  • Thanks Cheeky_47 bought 1520 couple of weeks ago and forgot to enable DP. All good now ta..
  • No worries, I did the exact same thing myself!!
  • Downloaded and installed europe L1320
  • It is over 30 minutes and my L1020 is still updating...
  • Odd. This was one of the quickest updates I've seen. In and out in 10 minutes, though many apps took awhile to update. Interesting.
  • I would love if this update restored Storage Sense to normal so that I can see and clear temporary files from it. Since one of the more recent updates, the only way I've been able to clear temp files on my 925 and 810 is through Storage Check. Meanwhile, my 920, which is already running Cyan does it exactly the way it's supposed to. :-/
  • Word.
  • Maybe imagining things. But my audio is better on my 930. I always use Bluetooth so when I came back to the podcast I was listening to before update, my audio suddenly has better bass response. Maybe MS updated my tired ears.
    This is actually more exciting than people are letting on. As we move closer to a Windows "Phone" 10 preview, updates like these may be more numerous.
  • I'm new getting used to windows and still learning everything , I know if I install developer preview I viod warranty, but if I install it is it hard to revert back if I have to? What's do I do? I'm not waiting for the folders ... I have a Lumia 630 8.1 already in it.
  • There have been no reports of anyone on DP not getting warranty support, so that's not a big concern. To go back to released software, you install Nokia Software Recovery Tool on a PC and reinstall the firmware and OS on your phone with it.
  • An employee at the Microsoft store said that it wouldn't void warranty.
  • It takes too much time to showing update...
  • Not sure what's been updated, but my 920 does seem snappier..
  • Ditto!
  • Transitions seem smoother too
  • All I noticed was that installed all the Bing apps...
  • Done!
  • Placebo update.
  • I think the reboot temporarily speeds things up.
  • True!
    It is ...
  • Was hoping they have called it critical to push firmware past carriers for preview users. Disappointed.
  • This actually fixed the Facebook BETA app to load contents and toasts alerts instantaneous. Thank you MS!
  • This is test for new update system which is processing by the same way with recent Windows 10 Preview buid update. Unlike before, we don't need to update apps which were already installed after system update complete.
  • I'm not sure where else to put this as I can't access Windows Central anymore from my phone. Noticed there was an update and now app keeps crashing. I have the critical update and am using my Surface to add this comment. Anybody else have problems? Thanks
  • I bet this is a pre update for the denim rollout which as I recall might rollout to carriers next week?
  • yeah that would be sweet if T-Mobile is skipping Lumia cyan and going straight denim...
  • Wait, critical to test update systems?  They must be about to run some serious changes to the phone where some might not ever return.
     
  • So... this update changed my lockscreen to a random photo? (It's a beach at night. After looking I found it in the default backgrounds.) Judging by how no one else has said anything, I suppose it's just me or rare. My only guess is it has to do with trying Tetra Lockscreen the other day and then disabling it. Edit: And the Start Screen seems to be a lot smoother for me.
  • same thing happened to me
  • This update breaks the Tetra Lockscreen App. See my post below. I got a warning message about it starting that they're ' may' BGR an new version of the App in the Store that's chopsticks, but there wasn't.
  • The blue water photo you are seeing is the default Lockscreen background.
  • which it was Lumia cyan but hey... and T-Mobile sure is dragging they're a** with the update as well... AT&T I'll see you soon
  • can they tell Verizon how to update a phone, please!!  Critical update for my Icon would be Cyan or better yet Denim!!!
  • Am I the only one having issues installing the update? The gears just keep grinding and then I get a Windows sad face. 8XT.
  • A few apps greyed out and stuck on installing after the update. Namely news, weather, files, surfy
  • Same here! I updated hours ago and I still have a load of apps, including Facebook, greyed out and stuck on 'installing'! Anyone know what's going on!?
  • Same here, re-installing the app solves it. Update installed fully in 52minutes, L1320 Cyan.
  • I too had this problem on my 1520. But, my wife's 1020 didn't.
  • Seems slower (glichy-er, studdering etc. And now my battery is draining super fast! 20% in a half hour. Nokia Lumia 1020.
  • Hmm My 1020 seems a little faster (not joking either). on things like scrolling the start menu up and down, switching to the app list and things like that.
  • Yeah, my 928 seems more fluid than before. It's a smidge faster....maybe the fluidity makes it seem that way.
  • Same here
  • Tap  scroll issue hasn't happened since update. 1520. I am sure it will be back soon though... ​ ​ ​ ​
  • I agree, although I'm in a weird position. I'm on my 7th, (yup, 7th), 1520 due to the scren issue. I got my current phone last night and ran all the updates then restored. I haven't had the problem at all with this phone but I have no idea if it's because of the phone or the update! I have very little confidence in this phone, I hope I don't have the same issue yet again but if I do it's off to Android and a Note 4 for me, and I know I'm not the only one....... I would hate to have to do that but the lack of acknowledgement from Nokia regarding this issue has been pathetic. Nokia and MS are their own worst enemy!!  
  • They are lazy. If there is a known issue with any device, it should be quickly fixed. Even with a flagship that happens too late or never happens. This questions their services. Poor I must say.
  • I got the update. Still on Lumia Black with my Icon though. Verizon sucks!
  • Same here... Verizon is awful when it comes to WP support.
  • You know, one of the reasons I still like my Windows Phone as much as I do is because of this community right here. You guys rock. Just sayin'.
  • Still when I take a picture using my camera button on my Lumia Icon, it takes multiple pictures.  Very annoying, stupid, and evidently not considered "critical".  So, I wait....
  • Cool! Now you have burst shots out of the box!!
  • First hearing of this, try switching the capture mode setting... 5MP and 16 MP only one photo in my icon camera roll
  • Well, now Cortana can flip a coin, so that's something.
  • Thats been in there foe a while. ASk her to roll some dice for you.
  • Really useful.. Why not push Cortana to all regions, that would be more useful.
  • Will it blend?
  • On my 1520 everything seems smaller
  • I have registered my phone with wp 8 sdk as a developer phone.but when I am trying to login developer preview program its saying u need a developer account.thn I connected my phone to my pc again and it says my phone is registered.what to do ? Plz anyone help me plz
  • Microsoft is just playing with you guys.... There is NOTHING critical at all with the update. It just like a fire drill. MS just took you guys for a free ride there.... LOL http://wmpoweruser.com/new-preview-for-developer-update-rolling-out/ Update: Windows Phone developer head Greg Sullivan has posted on twitter that the Critical update component of the update was in fact just a test, and did not in fact patch any critical bugs.
  • Yep I speak to Greg, this is testing capability to push updates as and when, bit like patch Tuesday.
  • Yeah, I'm laughing as I read th comments because this article even quoted Microsoft saying that it was just to test out the update system.
  • "fixes and improvements"
    From the article quoting Microsoft
  • Anyone got the update? Whats new? Still installing here..
  • It's seems to run a lot smoother than before.
  • It is because the phone rebooted, reboot more often
  • I don't know if the update made this, but my MSN Food app now syncs food collections with the desktop Windows app...
  • Last food update sorted that :)
  • Yeah... Thanks! I also noted that the app had updated herself through app store, however I only noted this after the os update, my food app live tile usually does not update, so I opened the app to force a tile update, that's when I noted the change...
  • All my msn apps stop live tiles work, did a full switch off/in live tiles
  • Glance weather on the lockscreen and glance screen isn't working after the update
  • Works on my L925
  • 122 packages on this update.
  • How much mb this is ....?
  • Mine it still says phone is uptodate
  • Could be wrong... But in Touch settings I see "Navigation Bar" for the key vibrations...pretty sure it didn't say that before. I have a L925. Also... In Glance settings there's an option under the colors that says "Hide Glance Screen". I could just be dumb haha.
  • I haven't updated to this update yet on my 1020 and the vibrate setting is there
  • no more fake LUMIA DENIM in extra+info... it say's LUMIA CYAN....
  • Mine says up to date.. I got no update!!
  • Prepping for cyan on icon?
  • Since updating I get a "Resuming..." screen each time I unlock the phone. I think I'm going to roll back... L1020
  • Do you have live lock screen or tetra? They do that for me.
  • Will I be able to use my treasure tag after this update? Didn't work for lumia black or cyan. Let's hope so....
  • I've got an 1520, and before this "critical" update, when you started the camera (Nokia Camera) with a locked screen, it'd take like 2 seconds "loading..." But now, it starts faster, not even taking a second. +1520
  • Same experience here..
  • This update is for upcoming update which is lanch in 27th Oct
  • This last update is changing my theme from dark to light on its own
  • Seems faster...no problem encountered in authenticator and extras + info compare to what others experienced ...
  • So... The only thing critical is that they want to test the critical update system? I'm gonna Wai and see if it forces me to do it while I'm in the middle of something like an AoE attack or a phone call... That would be so windows :/
  • This update made Terra Lockscreen quit working for about 15 min then it worked again with no app update. Huh.
  • Size just 26mb only, after update its seems much faster than earlier. I love Windows phone. Love you Nokia.
  • One more good news in this update. It charges the mobile too fast.
  • Will it support Tetra Background?
  • Yes it does.
  • Definitely fast on my Lumia 730 dual sim.. Even the lock screen button response is faster.. By the way guys.. 730 is kickass..
  • After installing this update my HTC 8x continues to reboot, called and spoke with HTC and was told since it is not under warrenty there was nothing they could do. Any ideas how to restore to working order?
  • Installed on lumia 820 and its seems faster..
  • But the battery draining issue not fix
  • Seems faster, drains battery like crazy and it causes my 925 to heat up like crazy.
    There's nothing wrong with my 1520 yet besides the battery drain
  • I have official wp8.1+cyan installed on my device. Will I get preview for developers update after installing preview for developers application ? And also will I get straight latest update (old+current update) or single by single ?
  • You'll get all the dp updates
  • I too feel the OS has got faster what's in this update anyway... Anybody gt the details...??
  • Probabaly becuase your phone did go through a soft reset process, as stated by others and MS them selves this so called critical update was a firedrill, test run to make sure futur updates will go off without a hitch. One thing im gonna say is that i noticed whatsapp is giving some notice about my connection and that i wont be able to receive all notifications or something, this has never happened before. 
  • update took only 5 minutes on L630 :)
  • Did the update and my treasure tag still doesn't work on my 920, I guess I lost $20 there. Unless I wait and get the Lumia 830 or an adroid phone...
  • I don't see any difference at all. Oh and btw, the update was 605MB on my HTC 8S.
  • 605 MB..!! It told 23mb in the details.. I don't understand... Are u sure..??
  • Need to install this into wifey's 1020 and see if it helps the random freezing issue..
  • Well one thing it did was to make my phone incompatible with the lovely new Microsoft Garage Lockscreen app Tetra Lockscreen.
    After the updates it said that it was incompatible with Tetra, and that an update may be available in the Store, but there is none. Pity. I was really looking that program.
  • I'm not able to download the update in mine pls help me out guys does it wifi
  • My phone seems totally different from the comments. Its taking more time for loading n resume application
  • Noting different I get
  • Make sure ur enable preview for developers box is checked in... Then goto phone update and u'll see the update there... Coz this update is only for developer preview....
  • Just compared ma 520 speed wid another 520 running the non updated os nothing has changed the performance is the same guys... Its all just an Illusion..
  • Just got the update and it doesn't change anything
  • My Lumia 620 (Dev Prev) doesn't connect to PC via USB after cyan update.Also Battery seems to be draining really fast, I hope this resolves some of the issues i am facing..
  • Same here, but before the firmware update (cyan) mine happened after updating into 8.1
  • But did u manage to resolve the issue??
  • Nope still suffering the pain in the ass
  • Same here:(  
  • Seem fix the Lumia 1520 screen too sensitive issue for me!!
  • I downloaded the update using 3G connection. Installation takes long time, been around 40 mins and I still see no progress in installation, any thoughts on how much time it takes?
     
  • Yes, screen sensitivity is now much much better. Fingers crossed it stays like that....
  • No love for the 810?? Geez!!
  • Its not available for me in India. What should I do?
  • For the first time ever, my Nokia Lumia 928's home screen is lagging after this update..... What gives???
  • All apps are getting reinstalled
  • My Icon does seem faster.... or could that just be from the restart?
  • It gives Cortana to Indian Regions
  • Seems to have increased the digitizer velocity!!
  • It has become smoother.
  • Is this update actually newer than the 14353 update for the Lumia Icon/930? I would't want to "downgrade" my 930 :) Update: just compared the version numbers of the OS - the version number of the new developer program update is " 8.10.14192.280", the one for the 930 was 8.10.14176.243. So it seems the DP one is newer :). Me thinks me is gonna enable the DP again, to get this update...
  • What's the update is about?
  • For what it's worth since yesterday's 'critical' update my Nokia Lumia 620 decided to crash overnight. Left it as usual with WiFi on, Quiet Hours on and Alarm on. 7am alarm goes off but I cannot dismiss it and phone stops responding - freezes. Have to remove battery to kill Alarm and reset phone. Now phone is almost completely discharged.  Prior to this latest 'update' the phone was fairly stable with average battery life and only the usual reported bugs like backup failing etc.  Over on the MSFT Community site I see dozens of pages of similar reports.  This phone is on the Preview for Developers program and has the latest updates and Cyan firmware. It is also a CV UK model on the 3 network.  I don't really expect any assistance from this site anymore but feel it is worth letting MSFT know that the Windows Phone OS may have great potential but is doomed to fail if it cannot be relied on to work properly.  Returning the phone to Nokia/MSFT is not an option for me and I don't have access to Windows 7+ PC to use the NSRT tool so unless MSFT or Nokia fix this major crashing bug then it will have to be i-phone or android for me.
  • that's the thing with dp, it hasn't got the firmware build for it, these problems are expected
  • Does thus mean it is just for testing and there is nothing in the update actually?
  • The update contains bug fixes as mentioned in the article. And it is faster and smoother.
  • I found that after the update, in Extras + Info it is stated: Lumia Cyan. Before that it was Lumia Black.
  • Little bite Faster, Lumia 820
  • my camera lumia 830 can not run anymore after this critical update. Anyone else?
  • No... From morning after update Lumia 1520 hang 3 times (unable to unlock the phone). :( 
  • try change your background image
  • I noticed there's more features in the glance screen section after the update on my 920...
  • The only change is that the boot up time is faster. The awful stuttering in the pictures gallery, files, and games hub apps hasn't been fixed on my 920.
  • Store's design changed a little
  • It's having bugs.. Unable to open email+ account in the setting.
    It simply crashing.
  • whats with the "critical" word??
  • Crucial was taken
  • Hmm... I think I'm out of luck with this update. It's been sitting on the cog wheels screen for about an hour now, with the white bar not even starting to fill up. I tried resettingthe phone (by removing the battery, no other way worked), and after the boot screen it goes back to the cog wheel screen. I left it like this for another 30 minuets now, but it doesn't show any sign of progress. Had 1.5GB free, and the phone is ATIV S. Am I the only one ? How long should I wait ? :(
  • For my L520 too, it takes hours.. I noticed one thing , if device heated too much this issue comes, I removed battery and kept back, restarting after cooling, it worked.. Low battery also another issue..
  • Please tell me what's new in this except it seems faster?
  • Please read the article.
  • No info is given in article that's why I am asking!
  • The last paragraph mentions bug fixes, ie. no new features this time. Microsoft is also testing their update systems with this update.
  • I have sommething funy: at my phone is not critical. Is NORMAL update, and is installing to slow.
  • No update for me. 930.
  • I've just realised I've always had 8.10.14192.280. Must have been released to 930 ages ago.
  • Much faster
  • When i read 'Critical Update' i thought it would fix the color problem with my 930, but no. No sir. Critical my butt... Apparently there's nothing new about it. It appears to boot faster, but that maybe just a placebo effect.
  • So you think Microsoft just did it for fun? Come on man...
  • For testing purposes maybe or to fix some unoticed bugs. I don't believe it was for fun. :) But it sucks to buy a flagship device which supposedly has a full HD display and the darn thing changes tint acording to brightness and heats so much that the back cover opens.... That is making fun of us customers. And the phone already had the same problem in the 'older' model 'Icon' (which is exactly the same except for the bands), yet they released it again. Yep, i'm pissed about it. It was expensive. I sent it back, they replaced it and it came with the same problem. Gonna do it again and i'm pretty sure it will come with the same issues.... It feels like i'm working for them and paying for it.
  • Update is Stuck in 28% ... Help me L520
  • Sam, are you sure of that"5 to 10" minutes thingy? I'm asking because in my case, even though the damned message says 5 to 10 minutes, my phones have never complied to that directives even for once. So I believe Microsoft may somehow be lying. What do you think about this allegation? Please let me have your opinion after the break.
  • Depends on how much data and apps you have on the phone.
  • I think something is going to happen on that date. Otherwise it won't be a critical update
  • Besides placebo "speed"...does anyone know what this update does? Security fix? Setup for denim? Seems like nothing changed to me.
  • Bugfikes and stability improvements
  • I'm unable to complete the update
  • Since update, on my 1520.3, I have poorer network performance
  • I don't know if it's because of this update or something else but the Windows store app shows larger images for popular apps.
  • +1
  • Oh the joy of being chained to Sprint. Still no Lumia devices and no critical update available for my Ativ Neo.
    I WAS really jazzed when Softbank bought em out...really really disappointed that they have chosen to be the bottom feeder again/still.
  • It's crap!
  • My Lumia 820 is suddenly short of 1gb of internal space... Anyone else experience that?
  • Fasterer.
  • Yeah got it...thia morning.....what was it for??
  • Yeah got it...this morning.....what was it for??
  • My screen is SUPER sensitive Now - dont want it - stop it!!! Even when lovering screen sensitivity.
  • Lumia 1520 screen over sensitivity issue never fix no matter how many times updates.
  • Just updated my 1020 with the "critical update", and now i found that I am updated to Lumia Denim via extras+info.
  • Alarm failed after update
  • Battery drying issue On My Lumia 625 is completely resolved.....It may be coincidence but im happy to update My phone
  • I want my sprint mms back already lol
  • Is it just me or the system sounds are somehow turned off. The phone lock sound has disappeared. The sound when we add a word to the phone's database is also off. Has anyone else experienced this?
  • Have Verizon and HTC 8x..lately it has been lagging and stalling. This update seems to have fixed it..running much smoother and very fast now
  • Tmobile 925,after applying this "critical" update, my microphone stopped working,I can hear anything,I only can speak from speaker,did anybody have that issue after update?? If you have solution please let me know otherwise I will throw this freakin phone!!
  • For a moment I saw this update on my Icon and thought hell just froze over.
  • cannot migrate a couple of apps after updating, including MSN News, Travels and Viber ... Had to reinstall. WTF? :|
  • 925 todo bien...
  • Not sure if this was already reported but I believe this update removed my option for a front facing camera on my HTC 8X.
    Windows 8.1 Update 1
    OS 14192.280
    Firmware .650
  • Seems critically faster.....
  • Is anyone else experiencing issues with apps saying they are installing and not usable after this update? In my app list about 50% of all apps are dimmed down like they're still being downloaded from the store and not usable. I go to the store and there are no active downloads. Already did a restart and no dice.
  • It seemed to fix my super lag that I had when scrolling.. Nice!
  • Perfect
  • The App store is definitely different. New layout
  • Wahoo. Fixed internet sharing on my Lumia 1020!
  • When we long tap tiles on start screen it floats!
  • Using a Lumia Icon -- ran the update about an hour ago and since then my phone has rebooted 3 times without any interaction from me. It's been stable for about the past half hour, so I'm keeping my fingers crossed. Anyone else experiencing this?
  • Also I'm suddenly getting many more high quality matches on 6tin. Thanks for the update Microsoft!
  • Brilliant 
  • Seems faster!
  • After the update unable to connect a google account.
  • HTC 8S Users:
    Afternoon I download & installing this update and my 8S have ability to get GDR 1.
    Now I create folders on my start screen and processing faster!
    Thanks Microsoft.
    Thank you Sam Sabri for this awesome article dude.
  • Haltintoprak
  • I just did my update too Lumia 920. I dont quite feel any significant change in performance, seems pretty much the same to me.
  • Currently downloading (TMo Lumia 925) LOL to that first ever comment.. "SEEMS FASTER."
  • Well I've definitely noticed a difference since this update. My L1520 is missing out notifications, the lock/unlock tone no longer works and when I plug in my charger or place it on the QI stand, the battery charging tone no longer works either. I'm sure I'll notice more broken stuff in the days to come..........
  • No new PforD update on either my 925 or 810, Friday evening. Checked OS, number, no change.
  • Its seems like i m only one who is facing error in installing... Error code 8007000d
  • Hey Sam, sorry this is coming in a little bit late this is because other sources just won't work. My update screen is stuck on 79% for about a day now. Pls how do I cancel and restart the update all over again?
  • May be!!!
  • Well, since this "non-update" the battery saver now longer turns off the backlight on the capacitive buttons on my 1520 making it a downgrade for me
  • Well, since this "non-update" the battery saver now longer turns off the backlight on the capacitive buttons on my 1520 making it a downgrade for me
  • Since installing this update the battery saver now longer turns off the backlight on the capacitive buttons on my 1520 making it a downgrade for me.
  • I have some new features on my phone now and there is another update from Nokia
  • Since installing this "critical" update, the Battery Saver no longer turns off the backlight on the capacitive buttons on my 1520.
    This makes it a big time downgrade for me as I use(d) this feature any time I was reading in a dark room and didn't want to stare into the "oncoming headlights" like glare of the capacitive touch buttons.
  • "I don't expect any assistance from this site anymore" true dat :| Comment section is often a pile of juvenile non sequiturs'.
    This update was more of a downgrade for my 1520 as well. Most annoying of which is the Battery Saver appears to have lost functionality. Specifically, enabling it no longer turns the backlight for the capacitive buttons off.
    Having no.actual baseline to use, I can only ad that it seems like the battery drains faster now as well.
    If you find any sites with a supportive membership of enthusiasts anywhere, let me know :)
  • Anyone else having Bluetooth problems after the preview update????
  • Not getting this update on my Lumia720, location india
  • I updated my phone and it stopped connecting to my pc using the update before this one 3 weeks ago
  • All this update got for me is the logging in capability to facebook in Cortana i.e. my Cortana always used to show my facebook as logged out and I wasn't able to log in at all. However, now I am very well logged in at first attempt. P.S: I had tried restarting and other stuff earlier but didn't work.
  • However, I don't know how iamtenchi got Lumia Denim on his extras+info. I am using a Lumia 1020 too with the Windows Update 1, but my extras+info still shows Cyan
  • It's a false reading, I have the same thing on my 1520.
  • Yes... I hav Lumia Cyan now.... Thank you Microsoft
  • I had the preview of developers windows phone 8.1 and after 2 updates
  • Thanks Microsoft.
    I updated my 8S and my phone is running GDR 1 Update.
    It works faster and again i love my 8S!
    Thank you Sam Sabri With this awesome article.
    I love you dude!
  • Lumia 521.. after getting the Critical Update, my lock screen is very slow to show up. It says "resuming" on the screen before showing the lock screen. Anyone else having this problem or know how to resolve this problem? 
  • I hope this update fixes the 80188309 update issue. I can't update to lumia cyan or denim since I'm on the DP program. I do have some technical insights but I do not have  a lot of time to uninstall/reinstall the OS and reorganize my phone. I don't mind the locker issue not working. I just would like to continuing updating to cyan an denim through the DP program. Can anyone confirm I can continue updating to cyan and denim after this "critical DP update"?
  • just installed it and i got cyan on my preview for developers here in east Africa im using a lumia 625
  • Is anybody missing the "Quiet hours" selection in the quick action menu?!
  • I'm having a big issue with this update. It's been updating for hours now (you can see the gears rotate), but there is no progress in the bar. It hasn't even started yet. I can't use my phone untill this is fixed. PLEASE HELP me.
  • I had similar issue with 635 and here is what worked for me. 1. Remove SIM, SD Card and Battery 2. Let unit sit 5 min 3. Re-install Battery only - connect to USB Power 4. Be patient with install - but should progess...   5. After completion - reinstall SIM & SD... No guarantees - but thats what worked for me...  good luck
  • After the 'Critical Update' finished: music doesn't work, calendar doesn't work, battery sense doesn't work, the files app doesn't work... Lumia 520.
  • I found music wasn't working for me either, I did a restore, all good now and the phone is working great!
  • My phone run DP but now after the update my phone runs Lumia Cyan, the official Windows phone 8.1... Thanks Microsoft
  • 625 bile hızlandı. 
  • yay, this got rid of the u2 album off mine!
  • Well, when scrolling to left or right stopping and holding finger on screen, it makes scrollable content jump left and right. Same thing when scrolling up and down. Until now that was not happening. It sucks.
  • Hi everyone, I've been a windows phone fan from the beginning and I enjoy windows phone central for its up to date info on its site for all u wp8 fix.....

  • Lumia 521.. after getting the Critical Update, my lock screen is very slow to show up. It says "resuming" on the screen before showing the lock screen. Anyone else having this problem or know how to resolve this problem? 
  • I have that exact sme problem on my 1020. These updates seem to make my device slower.
  • Well the flash on my 920 was not working, but after the update the flash is working again, so great :)
  • Thanks Microsoft for this critical update it real critical solution for my Lumia 920. My Lumia was dying after this update it running better. My Lumia was totally hang often, compass sensor and brightness sensor not worked and phone was hanged after entering program of preview for developers. I was tired often used software recovery tool and hard reset but no any solution. Now after this update and checked for two days I am telling you that this is really critical update... Thanks
  • What's new in critical update????
  • Installed on 928 yesterday which previously was running pretty decent on the latest 8.1 build. Unplugged from charger fully charged around midnight about ten feet from a wireless router to which it was connected. Woke up at 7 am....phone was off and battery was completely flat. What a buggy mess we VZW subscribers must endure to enjoy the new hot. Will be firing up SRT later this afternoon to go back to WP8. Drastic and twitchy move, perhaps, but this ain't my first flirtation with 8.1 on this device.
  • So I got the update yesterday and installed seemed to go fine and phone was working afterwards but I was on the phone in the car and once I unplugged from power source my phone shut off (battery level was fine) and I was in the middle of a call. I turned back on and called friend back said I would call back. I went to all back 15min later and realized my phone was essentially bricked. couldnt swipe up or down and hitting the power button did nothing. I tried resets and battery pulls and nothing really. the longer I left the phone untouched I felt like it got alittle better...got to the point where I could swipe up and type in password but nothing happened from there. I left phone plugged overnight and this morning to my surprise phone seemed normal. I shut off and restarted and its back to being bricked again. WTF? Phone calls dont come through but they dont go to VM right away as it would if phone was dead. I have an 822 on VZ.
  • Not sure if anyone else experience this - so have two 635 and one 521 - TMO US.   One of the 635s would not process the DP update correctly.  Update downloaded fine, device rebooted and then the infamous spinning gears - but would never process.  You see like a 1% processed on progress bar and then it would disappear and start over.   Did this for hours.   If you tried to power down or even just pressed volume down the unit would just restart and re-enter the update process.   Unit almost seemed bricked and would not even respond to hard reset keys.   Only way to shut down was remove the battery - but on reinsertion would boot right back into update process and still not respond to hard reset keys. So here's what finally worked for me. Removed SIM, SD & Battery and let it sit for 5 min then re-installed battery, connected to USB Power,  left SIM and SD out then finally it took.  Reinstalled SIM and SD and all seems fine know. Still a bit concerned that I may have some hardware ready to fail - but at least this approach got me back working.    
  • My critical update was to finally ditch my Icon using 8.1 since hell will freeze over before this platform catches up with iPhone and Android.  That's too bad because I really liked the idea behind WP.  As Ballmer once said developers......  One of the ads on this site claims 80% of WP users don't have a credit card. I don't think that will attract too many developers. Microsoft needs to skin WP on top of Android like a good version of touchwiz. At least they would finally have some quality apps. It was tough to make this move but I'm so glad I did. Bravo to Microsoft and Satya for realizing how important it is to support the other platforms. 
  • Hello Folks, Just did an update 10 hours ago and the wheels are still going on doing the update. Is that normal? I am not sure anything is going on, but it does seem exceptionally odd to take this long, whereas the update indicated it should not take more than 10-15 minutes. Can anyone advise what I can do to bring this to the updated state or the state before the uprade? Any help is appreciated. Thanks and regards,
  • As commenters before you noted, taking the battery, sim card and sd card out for five minutes, and then replacing only the battery and powering on can often solve this problem. That is, if your phone has a removable battery.
  • Hi every one I want to knw does critical update support for Lumia 630
  • Since installing this update my Lumia 920 has had intermittent signal.  Initially I thought there was an issue with AT&T in my area, but then I went somewhere 20 miles away and it was still happening.  The signal will be strong for a while then will suddenly drop to no service.  It does it all day long, back and forth.  Has anyone seen this issue reported by anyone else? I'm really hoping my phone isn't dying because Ive been trying to hold out for a new high end phone from Microsoft, if they ever announce something.
  • creating folders not happening in Windows home screen in,my 625 Lumia and NO Crotona we did passable setting in my 625...
    No Glance screen. UPDATE TO 8.1 NOT (PREVIEW DEVELOPER) NOW WE DOWNLOAD THIS APP BUT I TRIED TO LOGIN MICROSOFT ACCOUNT NOT HAPPENING .....
  • For Ativ S users!!!, this update finally fixes update error!! So no downgrading or flashing anymore! Just update through developer preview! Update 1 and all it's features (livefolders) available at last. I'm really starting to think WP is the most stable and well maintained OS of all. This would never happen on an android phone in a million years >_<  Ativ S's android twin the Galaxy S3 died sometime ago >_< (dropped from updates). Who's got the superior OS now? :P #GO-MSFT!! 
  • Maybe it will fix the wierd camera hanging and failier to load that resulted in a freeze that becuase of no removable battery required to wiat to drain. though I didn't try one of the reset tricks becuase I don't understand it or know how to do it.

  • Yesterday I installed CYAN as well as "critical update" from WP8.1update 1 i dont know what made the change, the phone is really faster and loading screens has really reduced.
  • During update error 8007000d coming...update was already download but cant install
  • I notice changes over the glance screen. You can add date, quick notifications, and detailed app notification to the glance screen. I think detailed app notification is new
  • My Lumia 920 freezes occasionally after the update. It's really bad. Any solution?
  • Lets face it, i havent find a full fault with any updates so far, its always better for me at some point.... So i am gonna continue follow them until its finally perfect! This one seems to fix the lags and the switching between apps. Less resuming and loading waits. I'm pleased
  • broke my ATIV-S - no signal now.  
  • Not available for Lumia 720,India
  • After getting updated this critical update and used for two days, today morning @0630 hrs my Lumia 925, while rebooting strucked with power&wheel symbol. Is it because of this critical update? If yes, please review.  Mobile NOT YET restarted till now. Still NOT STARTED and showing the same symbols... Worst experience!!!!
  • OK for a windows focused blog you seem to be behind on what updates do what I enrolled in PFD yesterday and since then I spent all night updating my phone and I love it Start screen folders and Cel Data in action center I am currently on 8.10.14219.341 I cam here trying to see what the hell all the other updates did but cant seem to find it Just Folders and the extra Action Center Icons and I think a few more colors to choose from for your tiles.
  • Ive just got the MS band for christmas. After syncing with my Verizon Lumia Icon which had version 8.10.14176.243 d.e. immediately asked for the critical update. In tolal 3 updates where done in a day. 8.10.14176.280 8.10.14176.306 8.10.14176.341 (just this morning) I think its because the MS band that I had to update. Since I had .243 for month now with no update request.
