Microsoft has now pushed a new Windows 10 Mobile Feature 2 preview build to insiders in Fast Ring. The Windows 10 Mobile Build 15252 can be installed now on your phones.

There are no significant changes here too. Apart from some fixes, however, there is one only change and that change is in the version number of OS. After this update, the OS version number has been changed to 1709.

Windows 10 Mobile Build 15252 Changelog:

  • This build includes all the improvements from KB4038788.
  • In preparation for the release of the Windows 10 Fall Creators Update, the product version number has been updated to 1709 just like PC.
  • We fixed an issue where, on powering the screen off/on, high demand for CPU could cause several apps to crash. Background processing of photos is an example of high CPU demand. In a photo shoot session, you may have seen the Camera app crash.
  • We fixed an issue with the Messaging app where conversation text was displayed incorrectly. Thanks to our Insiders that quickly highlighted this issue.
