Windows 10 Mobile Insider Preview Build 10166 arrives on the Fast ring

Yesterday, Microsoft released a new Windows 10 Insider Preview build for PCs. That version was Build 10166. Today, the software giant releases a new Windows 10 Mobile Insider Preview, with the same build number. Try not to get the two confused.

The new mobile build is rolling out to Windows Insiders on the Fast ring now, and like its PC number-sake, it offers lots of small changes and feature tweaks, although the focus is mostly now on improving stability and squashing bugs. The Mobile release won’t be happening any time soon, but Microsoft is clearly keen to get all of the major issues dealt with quickly.

The majority of the known issues listed in Build 10149 have been addressed in this new release. Microsoft has also fixed the problem with the missing post-upgrade migration status screen. To anyone updating to Build 10149 it looked as if the process had frozen, when it fact it hadn’t. Another bug that has been resolved in the new build is the problem some Insiders encountered whereby they were unable to unlock their phones despite entering the correct PIN.

Problems with incorrect app colors have been resolved and the reliability of app downloads and updates from the Store have also been improved.

The tiny battery icon has been enlarged as well.

Microsoft suggests that once you’ve updated to the new build you go to the Store and grab the latest app updates, as there have been lots of improvements made to those in recent weeks.
