It's another day, which means there's another Windows 10 build. Today saw the release of Windows 10 Insider Preview build 14390 for both PC and Mobile.
Dona Sarkar has requested that Insiders try out this build, and even give their devices to friends to try out as well. After that, you can provide feedback in the Feedback Hub.
As Dona says, "we’re getting down to the wire" with the Anniversary Update; indeed, you'll notice that the release notes are getting smaller and smaller. The Mobile build didn't even have any fixes listed. Rather, it's just a few known issues.
With that in mind, here's what's still broken in Windows 10 Mobile build 14390:
Voice Recorder does not show up consistently as an option for Call Recording. We heard your feedback and plan to release a Voice Recorder app update via the Store soon that has the fix for this issue.
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.
Keep in mind that the third known issue isn't really something that has to be fixed for the Anniversary Update. It's just something to be aware of.
Still, there are clearly just a couple more kinks that Microsoft wants to work out before signing off on an RTM build. It can be any day now.
If you're on the Fast ring, you can grab build 14390 by going to Settings -> Update & security -> Phone update -> Check for updates. If you're not and you want to be, you can download the Windows Insider app and set it to Insider Fast.
