Have a look at known Build 10152 issues below. The known issues may indicate that Microsoft is back to active feature addition to Windows 10 Mobile.

Build 10512 known issues:

  • Mobile hotspot doesn’t work in this build. When sharing the Internet from your phone using Mobile Hotspot, devices will fail to get a valid IP address from your phone and will show no internet access.
  • Two-factor authentication for your MSA with a phone number doesn’t work in this build. If you reset your phone and go through the first run experience, you won’t be able to input more than 2 characters for validating phone or text authentication. If you have a secondary email for two-factor authentication – you can choose that. As a workaround, add secondary email for two-factor authentication.
  • Some phones might spend a long time in the post update migration experience – just let the phone sit and it should complete this migration.
  • Apps that use background audio such as Groove, Podcast, Pandora, etc. will crash when launching after receiving an app update from the Store. Rebooting the device will resolve this issue.
  • Some phones with a large number of tiles pinned to the Start screen may get stuck in a state where the device shows “Loading…”; the device will need to be reset or rolled back to Windows Phone 8.1 using Windows Phone Recovery Tool.
  • Some apps may fail to update through the Store with the error code 0x80073cf9; uninstalling the application and reinstalling it will resolve this issue.
  • The Movies & TV app will not work in this build (video playback is currently broken).
  • One other note is that the Insider Hub is not yet included in the new build. We are working to bring this back into new flights soon.
