Microsoft today rolled out Windows 10 Mobile Build 10586 for Insiders in the fast ring. It doesn’t include significant changes but includes several bug fixes and improvements. This should be the preview build before the final RTM version is released to everyone very soon.

This build should also be the one that rolls out on the Lumia 950 which is Microsoft’s new flagship phone that goes on sale later this week.

Here’s what microsoft has fixed in this build according to the blog post by Gabe Aul:

  • We have fixed the issue that caused the Start experience to become corrupted (garbled) after upgrading and restoring a backup from a phone that had a different resolution.
  • You should now be able to set your default save locations via Settings > System > Storage and it will correctly reflect the current storage settings. Your SD card should no longer show up as a garbled name in Storage settings either.
  • Moving apps to a SD card should no longer cause those apps to crash.
  • We’ve made improvements to the Messaging + Skype app – through both app updates via the Store and also on the server side.
  • This should be seeing less resuming/loading text when switching apps.
  • The physical camera button should be working again if it wasn’t working for you before.
  • Apps and games should download from the Store more reliably.

And, as always, there are some known issues with this preview build which include the following:

  • After we released Build 10581 to Windows Insiders in the Fast ring, we discovered a bug in the build that will cause the filesystem to become partially corrupted after doing a factory reset. For those of you who did a factory reset of your phone, you most likely did not notice this issue on Build 10581. Due to this bug however, upgrading to Build 10586 will cause your phone to go into a reboot loop after the upgrade completes – rebooting at the Windows or operator logo. To recover your phone, you canuse the hardware key combination to reset your phone which will then put it at the OOBE experience on Build 10586. We highly recommend that you make sure you do a backup your phone *before* upgrading to Build 10586 due to this bug. Additionally, you can also recover your phone by using the Windows Device Recovery Tool to go back to Windows Phone 8.1 and then upgrade to Build 10586.
  • Deploying Silverlight apps through Visual Studio to your phone still won’t work in this build. This issue will be fixed with the release of Visual Studio 2015 Update 1 on Nov. 30th. You can deploy UWP apps to your phone without any issues.
  • There is a known issue where the tile for Insider Hub still remains under All apps but doesn’t open. Insider Hub isn’t included in this build. There isn’t a way to get it back unfortunately. However, it’ll return in a future flight! In the meantime, use Insider Hub on the PC as a workaround.

To grab the latest build, head to Settings > Update & Security > Phone Update.
