Microsoft has quietly released a new preview build of Windows 10 Mobile, with the version number 14295.1005, to members of the Windows Insider program on the Slow ring.
This is almost certainly a minor update, with a few fixes and improvements. Microsoft also released a older preview version of Windows 10 for the PC, build 14295, to members of the Slow ring as well. Fast ring members got a new preview build for both PC and Mobile, with the build number 14328, on Friday. It added a ton of new features and improvements for Windows 10 PC users, but only a few bug fixes for Mobile users.
Thanks to everyone for the tips!
