On August 12, Microsoft pulled the trigger on Build 10512, which it made available to Windows Insiders on the Fast Ring.
"Our major focus on Windows 10 Mobile right now is on improvements to core quality," said Gabe Aul, the head of the Windows Insider program, in announcing availability of the new build.
Among the list of what's new in today's new Windows 10 Mobile test build:
- General improvement in overall stability and performance.
- Ability to set the Lock screen and background image from within the Photos app.
- Apps installed on SD cards now work after a reboot.
- Improved reliability of Data Sense notifications.
- Camera can now launch when the phone is locked.
- Notifications for incoming text messages are back.
There are a number of known issues, as usual, which Aul itemizes in today's post. Also worth noting: The Insider Hub is not yet back in the new build.
No new Windows Phone devices beyond those already supported are able to run today's build.
Microsoft is expected to make Windows 10 Mobile available on new Windows Phones and to and existing Windows Phone users later this fall.
