Microsoft last pushed Windows 10 Mobile RTM Build 14393 to Insiders in Fast Ring and you can read the official changelog by clicking here. The Build however has some known issues and these include issues with Basic Bluetooth and WiFi functionalities. Microsoft may fix these issues with cumulative update builds but it is surprising to see a Build marked as RTM still with such issues that can mar usability. We have been highlighting Bluetooth related issues constantly in our Build reviews.
Windows 10 Mobile RTM Build 14393 Known Issues:
- We are continuing to investigate W-Fi issues on certain devices.
- Turning off Bluetooth can sometimes result in freeze, crash, or reset. See this forum post for more details.
- Wallet users are prompted for a PIN twice when using tap to pay from a locked phone. You can enter their PIN twice and tap as usual once the phone is unlocked. A fix for this will come as a Wallet app update via the Store.
- REMINDER: 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 will stop noting this going forward.
