So, the installation went almost without any problems.
The 2 things i did notice and i suppose that is some kind of a bug and/or glitch, maybe not:
a. The status bar on top which shows the battery life, clock, net speed etc, changes from black to white and vice versa when ever i swipe left and right from the home screen. It doesn't do it always, but it happens here and there.
b. The auto-rotate function (when enabled in settings) doesn't rotate the home screen at all. It is not locked from the quick menu.
Is that supposed to be that way or ?
Cheers.
