This build also has some known issues that you may like to read before installing it on your phone.

Windows 10 Mobile Build 15213 Changelog:

  • 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.

Windows 10 Mobile Build 15213 Known Issues:

  • 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.
