Windows 10 Mobile build 14393.448 rolling out to the public

Microsoft has just rolled out a new public update for Windows 10 Mobile, bringing the build version up to 14393.448. This update features mostly bug fixes and under the hood improvements, rather than any new features as this update is a cumulative update.

Here's what's changed:

  • Improved the reliability of multimedia audio, Remote Desktop, and Internet Explorer 11.
  • Addressed issue that prevents users from connecting to a virtual private network (VPN).
  • Addressed issue with a scheduled task that doesn't run in Task Scheduler after reenabling.
  • Addressed issue to update the Access Point Name (APN) database.
  • Addressed issue with Japanese characters that are missing when converted by the Input Method Editor.
  • Addressed issue with the system tray showing no Wi-Fi connection even when Wi-Fi is present.
  • Addressed issue with Windows devices that disconnect from the Internet prematurely before users can complete their paid Wi-Fi purchase.
  • Addressed issue to update the new Belarusian ruble symbol to Br and the new ISO 4217 code to BYN.
  • Addressed additional issues with multimedia, Windows kernel, packaging release management, authentication, Microsoft Edge, Internet Explorer 11, Remote Desktop, Active Directory, wireless networking, Windows shell, graphics, enterprise security, and Microsoft HoloLens.
  • Security updates to Boot Manager, Windows operating system, kernel-mode drivers, Microsoft Edge, Internet Explorer 11, Microsoft Virtual Hard Drive, Common Log File System driver, Microsoft Video Control, Common Log File System driver, Windows authentication methods, Windows File Manager, and the Microsoft Graphics Component.

Now you know what's updated, make sure you get today's update downloaded on your phone! It should be available for all users outside of the Insider Program, and those in the Release Preview ring too.

  • Waiting to download now :)
  • Mine is stuck on 7%
  • Unable to install it: Error 0x8018830f
  • Same here (on release preview)  Getting Error 0x8018830f
  • Same. Release preview. In my case, Lumia 1020.
  • Same here . Release Preview. Lumia 730 and Lumia 735 Both
  • Same here L950xl
  • Same here, RP 640 LTE
  • Same here Lumia 535
  • Same here, on Lumia 930
  • (0x8018830f)
  • Same L1520 RP
  • Same error. Lumia 950 dual. Tried a reboot, still fails.
  • I did a soft reset, and now it shows that my phone is up to date, but, it is still on the previous build.
  • Me too.
  • Same Error on my Lumia 640 DS India. Tried searching for the code on the internet, found that it hapened years back too when Nokia released the Lumia Amber update back then. Still, could not find any reliable solution.
  • I am having the same issue.. :(
  • Same here. Lumia 650
  • I have Same error
  • Same error, Lumia 532DS
  • Go to Settings > Time & Language and add a new Language (may be EN-UK or EN-IN if EN-US is what you have). Restart and check for updates and install. Should go forward.  
  • Didn't add a language but changed the region. It worked. Preparing to install now. Thanks.
    Edit: It showed an error again. Tried switching to production but it says not connected to internet.
  • I had same error.
    Here's what i did. First of all stop insider build permanently by going in setting>update & security>windows insider programme your phone will require a restart. retart your phone. now your phone will be non-insider so you will be able to download this update without any error. just check for updates. i have lumia 730 . its installing right now on my L730. Try it out.   PS - it will require 1.24 GB of space so make sure you have enough space. :)
  • And it's done. phone works smoothly. So far so good
  • This worked for me, thanks
  • Same error 0x8018830f on my 950XL when trying to install 14393.448​. I'm on the Insider programme Release preview. I tried to optout of the preview but my phone does not comply to restart efter opting out. Any suggestions?
  • Try to make about 1.5GB free space in phone storage..though, only hard reset worked for me.
  • My phone has now updated correctly. Waiting for a couple of hours eventually opting out of the indsider programme voudl be done. When out of the insider the update 448 installed flawless and quick. And now I'm back in the insider programme again.
  • Opted out from Preview, installation worked. L925
  • Same here Lumia 930
  • Downloading......
  • One number difference from the pc version...wonder why
  • My best guess is that they did some additional fixes. Possibly they didn't have the mobile update ready by the time the November Update rolled out.
  • GOt it. Now downloading
  • "Public," huh? They seem to be skipping Release Preview a little too often nowadays.
  • Release ring is normal use before major updates.. Not minor
  • You are not correct. Release preview is for the current branch patches and updates including minor ones. Major updates are tested on insider preview. Also, my release preview device is downloading now.
  • It is available for release preview as well. Downloading now on my 950.
  • It does not have to always go to Release Preview ring first and then Production ring. It depends on the changes. In software development verification there is a concept called "Impact Analysis" where you see whether the changes done have high or low risk and whether they impact other components and potentially cause a regression. If confidence is high, they can push it to Production and Release Preview at the same time.
  • Exactly
  • Neat
  • I'll ahead of u guys
  • This change log isn't for desktops?
  • Windows is Windows. One core, one changelog.
  • So where is IE11 on mobile that's getting the listed fixes?
  • We have it. It's being used its engine instead of edge in every legacy app accessing the web (not UWP) for compatibility reasons.
  • I had the same doubt :-)
  • Phone's updating... Will have it installed when I wake up. Goodnight everyone! ;)
  • Anybody having problems with this seemingly small update? Download's quick, preparing is quick, then error with "Retry" button on my L640.
  • Makes complete sense do downvote that question, yes...
  • I have the same problem :(
  • 0x8018830F ?
  • jup, 0x8018830f
  • Same error here. Can't install it
  • Had the same error, tried it again and it went through.
  • I've tried about 5 times already!
  • I get 0x800b010f
  • Same for me on L640 DS
  • OK, maybe they've not "opened" it for L640 yet. There are posts on Microsofts Answers suggestion that's a reason for this error. I've tried rebooting and soft resetting, and still won't install. Maybe it'll be solved in time...
  • same problem on my L950 xl
  • The same with 950
  • "Have you tried turning it off and on again?" :D
  • Hopefully, they'll find a solution. I've tried about 5 times since morning..and even tried clearing space by deleting apps, and also did a soft reset..but no use..the same error flashes everytime!
  • On 730
  • Solution: Switched from Release Preview ring to Production => everything went smooth afterwards
  • Wasn't that the case with the previous update too...?
  • For me on production ring, the update is not even found....
  • Maybe you need to wait for some time
  • Didn't help me as it doesn't find update on production
  • Switched to production from release preview and checked for updates... It said your phone is up to date!
  • I'll try this
  • couldn't move out of the RP ring. it says "not connected to the internet". tried soft reset, no use. finally did a hard reset, and then again entered the RP ring..now it's installing on my 730
  • Same on my 950XL!
  • Me too. Other susers are reporting the same. 640 XL here  
  • Yes, downvote me for reporting the problem. Fckn fanbois
  • Me too..
  • Ya, but mine didn't prepare... It just went ahead an restarted.... Then an error message
  • Its back to prepare to install 17%
  • Same here, error 0x8018830f. Lumia 830, RP ring, US region.
  • Maybe it's an issue for RP ring
  • Yes, me too. the error code is 0x8018830f. my phone is 950 xl
  • Same on 950
  • Same here on 730
  • Is it recommended to do a hard reset after installing this, and similar, updates?
  • It's not
  • No. Soft reset is ok. Only if you encounter serious issues.
  • Of course not. Do you enjoy hard resetting every month?
  • it's not a matter of enjoyment but a matter of system performance. Rather than working on a patched system it might be better to reinstall th full release from the ROM. I'm assuming these updates flash the ROM as well.
  • Generally no, but you may find it working better after hard reset after 6-7 consecutive updates.
  • You talking crap
  • And the main thing I expect Is ' to get rid from slow charging error(some Lumia users facing this) '
  • yeah it is called the calender app and cortana reminders...
  • What do u mean? Those two apps are the reason for slow charging?
  • there was a comment asking about reminder app but i don't see it anymore
  • That slow charging error on my 640 drives me nuts many times. Its gotten less these days. Anyway, can't install this update even. Throws an error.
  • Same here
  • Change charge settings or use trouble shooting
  • Downloading also for me
  • Internet Explorer 11? How can I launch it on my mobile?
  • Not on Mobile. That part if for the pc side
  • Downloading now......
  • Screen tearing and screen blinking bug still persists in LUMIA 830
  • My Lumia 638 had the same problem but I have a temporary work around..
    I just adjusted the brightness profiles Low to zero and mid to zero. now I am using mid and the problem gone. You can find it in Settings Extras display.
  • Sorry, how can I do this please explain it to me? :O
  • I've had this since I first updated to w10 mobile
  • Yup same here on 830!
  • Yep can confirm this too. Don't wanna bust anyone's bubble, but I don't think this is ever gonna get fixed...
  • Havin issues to install, after "preparing to install". =[
  • Is this the "unified update platform" update?
  • Its not.
  • My phone's proximity sensor doesn't work properly since it came back from the servicing centre. No update fixed it yet.
  • sounds like it's fisically broken
  • Updated to Lumia 950 U.K C.V - hope this fixes random reboot issues.
  • It won't. Your battery is busted. The only way to "fix" the random reboot issue is to get a new battery. This is now a common issue for the majority of Lumia 950 XLs out there (check my post hitory here).
  • Improved the reliability of Internet Explorer 11?
  • L950XL retail, unlocked, finland. Downloaded, installed, soft resetted, booted.. Now comes the experience.
  • I'm not going to reset my phone.... I'll delete the update...
  • Why do you have to reset?
  • I got an error message saying i should
  • oh wow, ok. Never seen that before. I am on the spinning gears now. all good so far...
  • Do a soft reset...not a hard reset. Soft reset doesn't loose any info, data or settings.
  • SoftReset does not delete anything! Just press vol down and power for the phone to shutdown. Keep pressing and release only power when ms logo is on the screen. Wait for ! Mark and then release vol down... Angry birds Epic seems to run better now.. Typing also is a bit more fluent and responsive..
  • Soft reset didn't work for me..still getting error installing it.
  • VPN still not working after update on 950XL
  • Same here wtf it's been 4 updates that's 4 MONTHS and no fix ! Seriously hating Microsoft now.
  • Me too
  • My VPN works.. Using L2TP with cert against Synology NAS device.
  • I was waiting for that Belarusian ruble symbol to Br fix, that was high on my list.  :(
  • Downloaded and installed just fine on my 950XL.  Got warm but then cooled off once it was done.  Seems to be working fine at this point.
  • Same error ppl have been reporting here, Lumia 930. Funny thing is phone backup hangs at 1/3 of the way... Dunno if related.
  • I hope this fixes the issue with the Lumia 950XL home screen not showing up when unlocking the phone. I hate having to restart my phone just to see the lock screen background. Everything is normally just black...
  • The release more look like they are for PC not Mobile
  • Lumia 950 xl updated smoothly :)
  • The list of fixes seems to be applicable to PC, rather than Mobile...
  • It is applicable to both.
  • Call recording for old Lumias is what we need.L640 here
  • The update is available for insider in "slow ring" too of course ;-)
  • It bricked my Lumia 930. :( First time that's happened in a long time. Not sure what happened but it seems like I might be one of the only ones that it happened to.
  • Here is my trick for the ICON. If your phone gets really hot during the update this could be the issue. I use a cold pack - one of those plastic things you put in a lunch box. I put my phone on it whenever i do any updates and they always work. I have woken up to the update cycling and the then I get the battery symbol or the gear spinning and the reboot loop. I go to the fridge - grab the cold pack - and then let it go. It has never failed me. I always take my phone out of the case and place it right on the coldpack. The more direct surface contact the better.
  • Got an error for my 950
  • My 730 too. It downloads, but can't install.
  • Updated fine on my Release Preview 950. But the changelog looks like a PC version....
  • Oh boy! Almost the same issue with the previous update that was released on the Production ring (The previous updates wasn't available on the Release Preview for a while). It's fixed on my side by switching back to the Production ring. Yeesh.
  • Yep... Update successful!
  • Update installed fine on my L640 this afternoon. Chicagoland - if that matters.
  • Updated just fine on my L640. :))))
  • Can't install this build on my 640 XL release preview. I got a error message 0x8018830f
  • Same here
  • On 730
  • Me to, 950l
  • Same here :(
  • Getting 14393.551 on release preview right now... Lumia 640...Ok, it turns out to be .351. Running behind since I changed my wifi to channel 13, the L640 often does not connect. No problem on my 950xl. Now updating to .448.
  • Uhm...?
  • What is the point of these update my phone is still buggy.
  • My phone got stuck on "Goodbye".  After a few minutes, I decided to hold down the power-button until it buzzed.  The install finished fine.  :)
  • Cannot say I noticed any improvement except words recommendation got a little better.
  • 3rd part vpn apps like hotspot etc do not work still
  • Update went fine on 640XL, release preview ring.
  • Updated easily and didn't take long. I haven't noticed any difference yet. L830.
  • 950 stuck on MS logo, hope I dont have to hard reset!!!
  • I am not in the insider program. Do I need to be on the Release Preview ring to get this?
  • Read the article!
  • 950xl DS unlocked update successful this morning. So far so good everything working as usual. And battery usage was great today. Battery isn't hot and haven't had to restart.
  • Hopefully fixes Bluetooth issues. Takes forever to connect sometimes. And sometimes won't allow music initially and have to restart.
  • Still quiet hours cannot use as edit through breaklist as useless as it gone to zero contact automatically.
  • Apps loading faster especially Store app :D -Lumia 640DS
  • Got it. Feels faster, working great 950
  • Seems faster. Some apps finally work again and their live tiles and notifications. Really loving this update.
  • All working fine in my lumia //830
  • Update went fine on my L930 except it stripped my breakthrough list from twenty contacts to two contacts
  • As always since anniversary update no updates offered to BLU Win HD LTE. But as I see the problems mentioned above it seems that this is luck
  • My Verizon Icon went flawless, a good day!
  • Lumia 950xl ds. It says installing updates and runs into 0x8018830f error. I tried three times but in vain. Any ideas?
  • Same on 730. Some say you need more free space, but I couldn't get it installed even after freeing space. Some say, if you are in release preview ring, you need to go to the production ring, and reboot your device, and manually check for the update again.
  • Still no VPN fix this is frustrating it's a basic feature and very much needed yet they improve IE11 because people need something to joke about ,and Belarusian ruble fix. my life is finally complete !!
  • I have the same issue still
  • Running great on Lumia 730 as of now. No stuttering and better multi tasking......
  • Installed without issues on my 950XL.
  • It's done!! No issues...
  • Why is it that every time it fails to update with that error we have to download it from beginning! Doesn't microsoft have a folder to temporarily store the update until installation is complete!? It's a small update but what worries me is the bigger updates that can go wrong too. I'm on 640 xl.
  • I got error on first try.but after free up some phone memory it installed successfully.
  • How much space is required? I had 1.2GB free space, but it failed.
  • You'll need a lot more than that
  • to users facing error
