I'm updating now (went through "1 of 2" then "2 of 2" updates and now I'm on the 'Android is upgrading....optimizing app X of Y" screen).
The update on the first screen said there's various improvements (including having the camera icon on the lockscreen). We'll see. I'm also rooted but someone on that link posted earlier said they retained root. We'll see about that too.
Let us know if you keep root.
Pretty minor update overall.
No extra bloat thank goodness. The whole camera on lock screen seems unnecessary due to the volume down short cut key.
Does anyone know if this helps with the Audio issues during a call? I use a Bluetooth and have no issues, but a colleague uses the same phone normally and he cuts out frequently unless he adjusts the angle of the device. :-\
