Windows 10 Mobile Fast ring goes to build 15215
(All About Windows Phone)

This was from the very end of last week, but I thought I should at least put up a post in case any of the fixed bugs help regular AAWP readers. It`s becoming more and more obvious that the Fast Insiders ring for Windows 10 Mobile is becoming less the `unstable, early access` ring and more the `more bugs fixed than any other` ring. There`s clearly effort going into keeping the core of Windows 10 Mobile up to date and fixing reported issues, all the while that the feature and app development is concentrated on the `desktop` - at least for now.
