  • Build 14393 fixed an issue causing some battery drain on older devices like the Lumia 535, 640, 735, 830, 930 and Icon
  • Build 14393 fixed the issue causing Voice Recorder to not show up consistently as an option for Call Recording. A app update was released last Friday that fixes this issue. Make sure you have the app version 10.1607.1931.0
  • Build 14393 fixed several issues impacting Dual SIM capabilities. Using a device with two SIMs should work as it should
  • Build 14393 fixed Surface Books and Surface Pro 4’s bugcheck (bluescreen) due to a camera driver issue. The bad driver is removed on updating to this build and a new driver is rolling out via Windows Update.

Known issues for Mobile

  • In Build 14393, Microsoft continuing to investigate W-Fi issues on certain devices
  • In Build 14393, it can turning off Bluetooth which sometimes result in freeze, crash, or reset
  • Microsoft 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.

If you’re on the insider, you can update to the Build 14393.3 by head to Settings -> Update & security -> Windows Update -> Check for updates. If you’re not yet as insider members and you want to be, head to Windows Update but click on Advanced options. Under “Get Insider Preview builds”, click Get Started. Once PC reboots, go back to Advanced options and set the slider to the Fast ring or Slow ring. For Mobile, you’ll need the Windows Insider app.
