Microsoft just wrapped up its second Build 2017 keynote which delivered several exciting Windows 10 news, so what’s better to celebrate than fresh Insider builds? The Windows 10 Mobile Insider build 15213 is now rolling out to Windows Insiders on the Fast Ring, and this one is another minor update with several fixes and improvements.

As you may know, Windows 10 users are getting all the cool stuff these days, as Windows 10 Mobile is currently on a separate “feature2” development branch. Microsoft previously explained that this was a temporary measure, and that the mobile OS will rejoin the main development branch at some point. In the meantime though, Windows Insiders can check the following list of changes and known issues in this new mobile build:

Changes, improvements, and fixes for Mobile

  • We fixed an issue where the Battery Settings page caused the device to become unresponsive and appear to have hung.
  • We fixed a general issue where certain background tasks were being incorrectly starved under resource contention. This issue would impact music and video playback.
  • Under low memory conditions, additional app launches will cause the OS to run out-of-memory and the device will restart unexpectedly to recover. This fix detects the condition and blocks app launches until memory is freed up.
  • We fixed an issue with Microsoft Edge which prevented the phone from entering Connected Standby which caused battery drain.
  • We fixed an issue where the word auto-correction service would crash.
  • We fixed 2 issues causing the device screen to stay off when unplugging from the Continuum dock after screen has timed out normally requiring the device to be rebooted to recover.
  • We fixed an issue with the Notifications Settings page which made the UI appear unresponsive.
  • We fixed an Enterprise MDM issue where the policy could hide all pages except the Work Access page.

Known issues for Mobile

  • The copyright date is incorrect under Settings > System > About. It shows as 2016 when it should be 2017. Thanks to the Windows Insiders that reported this!
  • In some cases, the WeChat app may crash on launch.
