My screen keeps reseting to 30 seconds after I set it to anything else. I am on UD10 but it was happening on my OTA 2.1 as well.
I am also having an interesting issue with my new extened battery. It drops to 5% in a couple of hours but if I reboot, it jumps back up. I know for a fact that it is not really 5 %, because I talked and did my normall stuff for the whole day while it was at 5%. I rebooted it 3 times yesterday and each time it would jump back up to what seemed real.
BTW: The 5% thing does not happen on the regular battery.
