It’s time for yet another Insider build of Windows 10 Mobile. Dona pressed the big red button moments ago, releasing the proverbial Kraken with Windows 10 Insider Preview build 14379 – another entry in the saga of Insider builds meant to squash all of the remaining bugs in the Windows 10 Anniversary Update before its release in just a few weeks. As you might imagine with a build dedicated to getting rid of bugs, there’s still a few unsolved issues laying around that Microsoft is keeping a keen eye on.
- 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.
- We’ve heard you and we are investigating decreases in battery life on older devices such as the Lumia 830, 930, and 1520.
- We’re also 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.
- 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.
If you encounter any of these bugs while you go through the new build, you can lay off of the Feedback app – Microsoft already knows about them, and they’re being worked on right now. If you run into anything else, however, be sure to let the team know so they can polish all the imperfections out of the next build.
