On Thursday afternoon, some Windows Phone 7.8 devices received a new update that brought the build number to 7.10.8860.142. Many thought that this update would finally fix the problems with the Live Tiles in the OS not updating as promised.
As it turned out, that wasnt the case, but Microsoft has already pushed out a second Windows Phone 7.8 update that is supposed to fix the Live Tile problems. Microsoft has updated its Windows Phone history page to show the newer build, which has the string number of 7.10.8862.144.
Officially, the change notes state that the Live Tiles feature now has fixed "performance issues from a previous update." Indeed, the first Windows Phone 7.8 update was apparently responsible for the Live Tiles to not only stop their updates but was causing the smartphones to use up their battery power more than normal due to the bug causing the Live Tiles to generate continuous web requests.
Microsoft halted the rollout of the Windows Phone 7.8 updates a few weeks after this bug was found. Now it appears that the issue has finally been fixed which means the rollout can continue as planned.
