Dona hit the big red button and introduced the Fast Ring to yet another build for Windows 10 and Windows 10 Mobile insiders today – build 14372. The build continued to smash bugs leading up to the release of the Windows 10 Anniversary Update that’s coming out in just a few weeks. With 14372’s laundry list of tweaks and general performance improvements, there’s also the all-too-familiar list of known issues.

Here are the issues we know about in the Windows 10 Mobile 14372 so far:


  • We have changed the backup format for Windows 10 Mobile devices to reduce the size of the backup stored in OneDrive. As a result, if you do a backup on a device running the latest Windows 10 Mobile Insider Preview builds and move back to the released version of Windows 10 Mobile (Build 10586) and restore from your backup – your Start screen layout won’t restore and remain the default Start layout. Your previous backup also gets overwritten. If you need to go back to Build 10586 temporarily, once you are on Build 10586 you should disable backup so it doesn’t overwrite the good backup from Windows 10 Mobile Insider Preview builds.
  • We’ve heard you and we are investigating decreases in battery life on older devices such as the Lumia 830, 930, and 1520 (devices with SoC 8974 chipsets).
  • We’re investigating Wi-Fi disconnect issues – if you are experiencing an issue with your Wi-Fi disconnecting, please see this forum post and make sure to upvote Wi-Fi disconnecting issues in the Feedback Hub.

If you run into any of these issues while playing around with the new build, you should know that Microsoft is well aware of them and is presumably working to hammer them out of the next build. Apart from these, feel free to hammer the Feedback app with any problems you might find in the new version of Windows 10 Mobile.
