'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
