What got fixed, improved, and what's still broken in Windows 10 Mobile build 14379

If you like seeing new Windows 10 Insider Preview builds frequently, it's a heck of a time to be alive. Microsoft today released build 14379 for both PC and Mobile, just two days after releasing build 14376.

It's been quite a while now since we saw a new Windows 10 Mobile build with any major features listed in the release notes. Build 14379 is no exception to that rule.

As usual, there are fixes, improvements, and known issues. Here's what got improved and fixed:

  • We fixed an issue that could result in a stray focus rectangle becoming visible in certain apps, such as Groove or Cortana, after bringing up the keyboard.

  • We fixed an issue where the aspect ratio of images on live tile wasn’t preserved if they need to be shrunk, leading to them appearing stretched.

Here are the known issues:

  • 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.

This is the first build in recent memory that had more known issues listed than fixes. Perhaps it shouldn't be a surprise that that build happens to be a Mobile build.

Of course, if rumors are to be believed, Microsoft will be focusing on Windows 10 Mobile more in the upcoming updates - Redstone 2 and 3 - rather than in the Anniversary Update.

If you're device is in the Fast ring, you can grab Windows 10 Mobile build 14379 by heading to Settings -> Update & security -> Phone update -> Check for updates. If you're not, you can sign up by downloading the Windows Insider app and setting it to Insider Fast.
