Windows 10 Mobile build 10586.164 released to Insider Slow and Preview Ring

This afternoon, Microsoft is releasing a new build of Windows 10 Mobile for those on the Slow and Production Rings of the phone Insider program.

The release of build 10586.164 is up from build 10586.122 release six days ago.

The site says the expected features of this new bug fixing release include:

  • Faster saving of screenshots
  • Smoother video playback
  • Opening of PDF files in Edge improvements

Microsoft is likely to publish a full changelog of fixes and improvements on their blog and we'll follow up this article with a full listing of what is new when available.

To grab the update head into Settings > Update & security > Phone update > Check for updates. Users must be enrolled in the Insider program using the Windows Insider app.

For those on the Lumia 650, 950 or 950 XL and who are in the Fast Ring you will not see an update as those phones are on the 14xxx branch for Redstone, whereas this release is on the more stable branch, which is pre-Redstone.

  • And, here we go again.
  • Lmao
  • Awesome! Going to go download it now. The Windows Central Universal Application for Windows 10 Mobile on a Nokia Lumia 830
  • How 830 perform w10mobile? Is it good? :/
  • It's been very good. I did a hard reset when I first installed it (like the first or second 10586 Build) and I've had few issues since. A few crashes, some battery performance issues, some graphical glitches and hangs...but every build improves everything. I've been happy with it.
  • go for it, just do a clean install.
  • I do suggest a clean install when you first update to Windows 10 Mobile.
  • It is just as awesome on Lumia 830 as on other Windows phones. I can confirm. A little issues here and there but they aren't Lumia 830-specific like draining battery or screen blinking issue.
  • Great performance, but battery life is inconsistent. One day it's great, the next day it sucks.
  • ^^^ THIS - So much this. I couldn't agree more. Some days I have great battery other days I chew through it within a few hours. 
  • Same here on my 930. Sometimes heats up like a lava rock and drains fast and then a day where it drains 45% in 10 hours.
  • The Lumia 930 always had heating issues (connected to battery drain issues). But I understand what you mean.
  • Do you also have the issue, that the display turns off for half a second every now and then or is it only on my 830?
  • It's not specific to Lumia 830. It's a general issue with W10M which isn't fixed yet. You may vote for it in the feedback app.
  • I believe that is a graphics driver issue with Windows 10 Mobile in general. The Windows Central Universal Application for Windows 10 Mobile on a Nokia Lumia 830
  • Thx guys, but battery is very important to me, i have 20-25 hr with hard to moderate use. How about battery on 830 with w10? Is it very bad or?
  • Well the battery life with the Lumia 830 isn't spectacular as it is, but with Windows 10 Mobile it's inconsistent. One day it's better than Windows Phone 8.1, some days it's terrible. We'll see how this build fares. The Windows Central Universal Application for Windows 10 Mobile on a Nokia Lumia 830
  • Thx bro
  • Downloading to my 930. YEAHHHHHH!!!!!! Bring it on!!!!!!!!!!!!!!!!!
  • How big is the download?
    I recall updates for 10586 build being cumulative like PC releases. With only the necessary packages being downloaded and installed. Yet, every new build requires me to free up over 700mb space, and I have no clue what that's for.
    Lumia 640 on 10586.122 here.
  • 731MB for Lumia 830.
  • When is the official wm10 coming? We cannot be insiders forever!
  • Soon... In March 2056. When in India?
  • Lol Posted via the Windows Central App for Android
  • Maybe after the apocalypse
  • It's already out  I've updated my lumia 730, you need to do a clean phone reset to avoid any errors and yes "Upgrade over sd card is not supported" you need to free the phone memory atleast 2GB. Download Windows Upgrade Advisior. You're welcome
  • Its time to be an outsider Posted from Windows Central for Windows 10 mobile
  • There's no "Insider Preview" name anymore there :) Posted from Windows Central for Windows 10
  • So much builds with this before...
  • Give us the goddamn redstone build.... Posted from Windows Central for Windows 10
  • you tell 'em!
  • Let's hope they start updating redstone again, we stupid 950 owners upgraded and now are stuck on the same version for weeks and your branch is more stable....
  • Damn makes me want to roll back. Redstone has been giving me issues.
  • Oh Posted from Windows Central for Windows 10
  • Which phone do you have?
  • 950xl. It was great before Redstone latest build. Even previous Redstone didn't cause as much issues.
  • Wich country are you in? I have a 950 but locked to att and I can't get it.
  • Canada. I keep it on usa region and language because the Canadian store is a joke. They keep reviews and ratings separate by region. So way different results on app popularity. They need to make it global.
  • My Canadian 950 xl on Redstone is also bugfy as **** as of late..
  • You should be able to get Redstone on any device that released with Win 10. It is the firmware that AT&T has not released yet. Is this not the case?
  • I'm still on .1004 but just went on production ring, but nothing.
  • Same here Posted from Windows Central for Windows 10
    On the Alcatel OneTouch Fierce XL for Windows 10
  • Me too, not too many issues but it was better on old branch. Let's hope they close this branch with this build and port the fixes to redstone and start releasing redsotne builds again.
  • Good news. Was going to hard reset due to WiFi issues since last build but will now wait until after this build instead.
  • My WiFi issues were resolved with .122 (on 930).
  • Also available on Windows 10 PC.
  • No changelog no download Posted from Windows Central for Windows 10 mobile
  • I just did one yesterday Posted from Windows Central for Windows 10 mobile
  • I literally just signed up for the insider preview and finished installing .122 like 15 minutes ago
  • Lol
  • Goo again Posted from Windows Central for Windows 10 mobile
  • Lol! Posted from Windows Central for Windows 10
  • lolz same here exactly ,i was updating from 10586.36 to .122
    after the completion of the above i immediately recieved .164....;) 30% and downloading on 2mbps connection. 
  • Everything changes and nothing stands still.
    That's life :-)
  • Lmao.. Btw wait this is production build too?
  • I think it's for everybody. I got it as well. Non insider or outsider :)
    950XL UK
  • Non insider 950XL UA got as well.
  • Unlocked?
  • Yes
  • Doesn't look like a major update.  With this pace, it would take forever to get all the known problems fixed to catch up to 8.1's stability.  
  • Maybe this will fix the problem with trying to download and install additional languages and keyboards?   Fingers crossed   Using a Lumia 640XL LTE Dual Sim
  • Can someone confirm visual voicemail works with this release?
  • After being an Insider since eternity, it's time to become Outsider...may be w'll get the miracle of Redstone...why Gabe Aul why why why..
  • Any news on production release? Still need more production releases to prove MS has control over w10m.
  • Kind of makes me wish I didn't install Redstone with the weekly release of 586 updates. Posted from Windows Central for Windows 10
  • Hey Microsoft I am experiencing some error in build 10586.122 which I have currently. I think the bugs is on store when I am download apps from store , it does not show the parts of app that are being downloaded. So for this I have to always go to store to see whether it is downloading or not..!!! Please fix this...!!! You can make the Windows 10 mobile even much faster.
  • Is Blu on it this time? Guess its time to run to lunch and check =D
  • We need more stabilization... Posted from Windows Central for Windows 10 & My beast of a 1520
  • Damn it I just downgraded to 8.1
  • PC and Mobile same update, so the update over LAN will apply here too? for ex: the mobile will suck the update from the PC?
  • No, bro. They are completely different updates. They will download separately Posted from HP Elite X3 Build.00.10586.164
  • How you liking the elite? And how'd you get one???
  • Is anyone having issues with Microsoft edge?? I mean when i open any webpage in edge and start to scroll the whole webpage stutters and it's so annoying. I am currently on build .122
    Also i have never done a hard reset since build 10586.63
    Lumia 640 xl w10m
  • Sounds like a known issue, but no fixes yet... also affects apps that use the edge rendering engine. I find clearing the browser cache etc. improves performance and reduces the glitches. Ps - vote in feedback app!!
  • For my 720, till date whenever I start the update process, it begins normally. Then if the phone gets locked or I navigate to something else, I can never go back to the update page. It just stays on Phone update tab and then back to home screen. Does anybody else have this? Posted from Windows Central for Windows 10
  • I have 640 XL also an when I'm at web page is it on there for too long and it tends to reload. The page and just goes white, sometimes when the page comes back. I don't know it has errors or it's just not right. But I'm clearly having edge issues with web pages also.
  • If you leave update screen you will not be able to return it will constantly be stuck loading it.
  • I hope this build fixes Bluetooth issues... Ever since builds of 10586 I've been having Bluetooth problems. Whenever I make a call or receive a call the voice does not go through. If you then turn off Bluetooth or just disconnect, voice stops coming through the phone speaker... The only way to have voice calls to work again is by making a soft reset.
  • If any help, I also had problems with BT on my 930 using 10586. After the 122 update, I got it to work flawlessly. The trick was to delete all known BT devices and re-pair them. After this, no issue whatsoever (seems even more stable than in 8.1). I'm using Plantronics Voyager Pro+ and various BT Speaker devices. 
  • Unfortunately I've tried that but still no luck. It's doing the same on my Audi MMI car system and on my Jabra Freeway... I just installed this latest update and hope it works.
  • Hello Daniel, actually it is for everyone on 950/XL etc, I'm not an insider and I'm downloading it now! 950XL CZ unlocked
  • Please fix stupid freezing on HOME SCREEN on Lumia 1320....
  • Im getting it, and I'm not in the Insider program... Lumia 950XL, Sweden.
  • is this only for slow ring, I have got it on my Lumia 950 which is not on insider program
  • My Lumia 950 non insider is downloading now.
  • i will stay with redstone which is far more polished.
  • Except for the bug where it doesn't read texts over Bluetooth and sometimes calls fail. Takes a power cycle or soft reset to get it to work..but only works temporarily. Posted from Windows Central for Windows 10
    On the Alcatel OneTouch Fierce XL for Windows 10
  • Is it 8.1>>164 or 8.1>107>122>164??
  • It looks like update is available to non-insiders. I'm downloading it right now to 950XL CV PL
  • It's available for the lumia 950 just got it and I'm not an insider.
  • From what country and is it unlocked?
  • Unlocked, Canada Posted from Windows Central for Windows 10
  • Any one having Lumia 730, with build .122 , and if yes how it's working ,pls tell me somebody..coz I want install .164
  • I m using lumia 730 n i m in .122 build..its highly stable build atleast for more crashes .
  • Yeah I am using Lumia 730 on build .122 and it's highly stable. Downloading .164 right now.
  • Downloading yeah!
  • If only I could get the Windows Device Recovery Tool to work for my Fierce XL. Anyone have tips to get it working??? I followed the directions exactly. I would roll back to the .63 build it came with and go on slow ring. The Redstone build on Fast Ring has a bug causing Cortana not to be able to read texts over Bluetooth and at times calls fail over Bluetooth as well. I need this feature working 100% of the time. Been on fast ring for a long time with my Lumia 925 and enjoyed it alot. Now its time to go to slow ring for me I think.
    Please help if you can. I have a post in the Forums as well and a Problem reported on the feedback app. Posted from Windows Central for Windows 10
    On the Alcatel OneTouch Fierce XL for Windows 10
  • My fast ring 1520 are still on 10586.107, how come?
  • You need to change to Slow ring (or Release Preview) for now to get new updates for the "TH2 - 10586" branch. The Fast ring is already on Redstone (RS1) builds which are only available right now to phones that came with W10M.
  • is anyone else stuck on .107 ?
  • Yes, my ICON is..
  • When is official update is coming. Posted via the Windows Central App for Android
  • Yeah, att still has it t gun point but I've only gotten .1004 as of last.
  • How about we fix the inconsistencies now that the official launch time is just around the corner? Posted from Windows Central for Windows 10
  • All I want is a Microsoft Edge and Facebook fix, whatever it takes, to make them stop crashing!!!! I don't know if it's because I am on a Lumia 635 with low RAM, but using Edge and FB is near impossible. Let alone, the two apps I cry about are Microsoft's own! Come on.....
  • No more Hey Cortana ?
  • Bug on TMob...can't download while on Cell data. Says i am roaming...but i am not...
  • Using a 950? Or the Fierce XL? Posted from Windows Central for Windows 10

  • can anyone say me is force 3G network mode available in this release preview buid??
  • Is it only availed on 950s and 650 ?
  • This is for everyone other than fast ring (which is on redstone). Posted from Windows Central for Windows 10
  • Greece downloading to 950 non insider.
  • I'm not worried about doing it faster; I'd settle for being able to save screenshots at all.
  • Has anyone in UK got it yet ,? Posted via the Blackberry Priv
  • Yes, I've just downloaded it on my 930, seemed to be a very nice update until I realised that some sounds are now missing including the spellcheck word carousel when you select a word, the lock screen opening and the charger jingle when plugged in...strange
  • I'm not on and ring on my 950XL but I'm still getting it.... Is that normal?
  • Did you hack their servers?! Posted from Windows Central for Windows 10
  • When will it available for fast ring ..?
  • Just change your Insider app's setting, choose slow or preview then go to phone update ;)
  • In the network signal the upload or download arrow symbol was not seen in all the devices. Must be available in windows 10. Which will be great implement. Because e can find whether we're connected or not to the data connection
  • I am on the Fast Ring and this update is not available. Is there any problem on switching to the Slow or Production ring? And can I return to the Fast ring when new updates are available for it?
  • what is diffrence between Insider slow, fast and release preview? which one should I choose for my one n only primary phone?
  • Download an app WINDOWS INSIDER from the store. Everything is self explanatory from there. Just follow the steps.. Good luck.. W10 simply rocks!
  • I recently upgraded my 640XL to W10, chose for the Slow Version. Now I lost all my SIM contacts and my Outlook is not synchronising with my Google+ account, so I can't use the e-mail on my phone. With the new update I got today nothing has changed.. Does anyone has the same issue? or is there a simple fix? Please let me know. Thank you in advance.
  • 640. XL. I have this problem when I first made the jump from 8.1 to Windows 10. However, after calling windows or Microsoft information they told me to try to back up and sync up my contacts even know they were pretty much already gone. Um, I had to go back to 8.1 again redo the download all over again, except this time when I went back to 8.1. I believe my contacts were back again. I just had to back up everything and then go do. The Windows 10 upgrade or insider preview after I did all my 8.1 backing up so that might be your issue. I'm not sure. But I have had similar issues and it took going back to 8.1 or rollback.
  • Thank you for your post, I'll try to go back to 8.1 and follow the steps like you said. Appreciate the reaction!
  • No sound for lock screen opening, charger inserted or Wordflow carousel thingy anymore :|
  • Here's my issue. I have a Lumia 640 XL and the problem was is that I had to delete every single thing on my phone. I had nothing else to delete and it still would not except the update I finally deleted every single possible app that I could that's on my phone opposed to my SD card and the update finally went through after numerous tries. And restart didn't take the first time around. I had to restart numerous times and scan. The SD card for errors. So after about an hour and a half it finally worked.
  • Lumia 640 XL after this update the emails are definitely Jacked and not working error code. Um it's definitely just not working.
  • Hi guys I am using Lumia 730 in fast insiders and my build version is
    10.0.10586.107 i have not got this updated what is the solution? Nesanth
  • 640 LTE received update 10.0.10586.164 3 days ago,slow insider. For the record. Republic of Panama Seems stable or no worse. Never much to complain about. A few crashes prior releases. The apps screen looses transparency after you select an app and then return to app listing. Work around is swipe to home then swipe back to apps page. Oh yeah loosing progress when downloading from store. Have to open store I think again to get progress of download.
  • Battery drain on this version compared to previous is SIGNIFICANT on my Lumia Icon
  • I'm not on Insider Preview program, but I recieved 10586.164 update form the original release 107 build. Nokia 730. What does this mean?
