Today, Microsoft released the latest Fast ring build, which is Windows 10 Mobile build 15051. Unsurprisingly, there are no new front-facing features, since we"re so close to an RTM and Mobile builds rarely have anything new in them these days.
As always, there"s a list of fixes, improvements, and known issues. Here"s what got fixed and improved:
We appreciate several of you sending us feedback on this and last week, we focused on fixing issues that resulted in frequent reboots for some Insiders on Build 15047. If you continue to experience unexpected reboots, be sure to send in feedback to us via Feedback Hub so the team can take a look!
We fixed an issue resulting in certain inbox apps, such as Calculator, Outlook Mail, Outlook Calendar, Groove Music, no longer being present on the system after a hard reset.
We fixed an issue resulting in Groove Music not resuming playback after ending a phone call if the app became suspended during the call.
We fixed an issue where periodically attaching larger photos to a message in Messaging wouldn’t work.
We fixed an issue from recent flights where, in certain apps, if you had selected editable text and pressed Shift on the keyboard, the keyboard would crash.
We fixed an issue impacting certain UWP apps using pivots, such as the News app, where the pivot control could end up becoming offset after quickly swiping through the pivots.
We fixed an issue where asking Cortana to read a text message over Bluetooth with many back to back emoji would result in high pitched distorted noise.
We fixed an issue where after upgrading some Insiders were unexpectedly seeing the full QWERTY keyboard on the lock screen instead of the pin pad.
Here are the known issues:
We have discovered a bug that causes background tasks to not run in the background like they should such as OneDrive’s camera roll sync feature. Please double check your photos have synced to OneDrive on the latest builds. We’ve got a fix for this issue coming in an upcoming build where background tasks will run again and your camera roll will sync to OneDrive as expected.
If your device experiences an unexpected reboot, in some cases you may lose your call, text, and email history may be lost. We’re actively investigating this issue. If you believe you’ve hit this, please up-vote this feedback item In Feedback Hub.
Speech packs may be unable to download on this build.
As always, you should read through the known issues before installing a build, to see if it"s worth the risks. The first two seem like they"ll be fixed pretty soon, but the issue with speech packs has been around for a few builds now. The easy workaround for this is to make sure that you have the speech pack installed before upgrading to a new build.
If you"re on the Fast ring, you can install Windows 10 Mobile build 15051 by heading to Settings -> Update & security -> Phone update -> Check for updates. If not, go to the Windows Insider Program tab and tap "Get started". When your phone reboots, go back and make sure that you"re set to the Fast ring.
