Compared to previous builds:
I'm getting freezes that sometimes cause the phone to do a full reboot and other times causes the boot animation to appear (not full reboot). When the phone doesn't do a full reboot, I get a "systemui has stopped" message over and over again and I have to force reboot it.
Another thing I noticed is graphics glitches (rare, but happens) when using stock browser. I get big black squares cover that a major part of the screen.
On the pro side of this build, battery usage is better then previous builds.
