Known issues[edit | edit source]

  • Devices may experience a black screen for 5 minutes between spinning gears and final stages of the update. The exact time depends on the device.
  • The user is unable to set default save locations via Settings > System > Storage and it does not reflect the current storage configuration.
  • Deploying Silverlight apps from Visual Studio to the user's phone does not work in this build.
  • If the user restores a backup from another phone, the Start screen may be corrupted. The only workaround is to set a different background in Settings > Personalization > Start.

SD Card problems[edit | edit source]

  • If there is an SD card in the user's phone, it will show a garbled name in Settings > System > Storage page.
  • Moving apps to SD card may result in apps crashing. The only workaround is to reboot the phone.
