Microsoft is rolling out Windows 10 Mobile Insider build 15252 to Fast Ring Insiders, which follows the build 15250 released three days ago. The new bits includes all the improvements from the Patch Tuesday update released on Tuesday for the Production Ring, as well as two more fixes including one for a bug causing high CPU usage. Just like on PC, the version number has also been updated to 1709 in preparation for the Fall Creators Update.

Here is the full changelog for the update:

  • 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.

The previous mobile build 15250 finally brought the new security features promised some time ago, and we assume that the “feature2” development branch will only get more quality fixes going forward. Let us know how is your experience with this new build in the comments below.
