Microsoft has just released Windows 10 Mobile Build 14383 to Windows Insiders in Fast Ring and you can read the official changelog by clicking here. The build that brings a lot of fixes over the last preview Build 14379 also has its share of known issues. Read the issues below before taking the plunge.

Windows 10 Mobile Build 14383 Known issues:

  • Voice Recorder does not show up consistently as an option for Call Recording.
  • You can open PDFs in Microsoft Edge but won’t be able to use touch to interact with the PDF (such as scrolling, pan or zoom). When you try to use touch to interact with a PDF, it will constantly reload the PDF.
  • 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.
