Seems a lot more buggy than 2.0 so far to me.. Now my button lights wont work at all...
I just got it updated. My lights weren't working either. I restarted the phone again and now they are working fine. Seems to be a bit quicker. I like the new lock screen!
Yes please restart and check again, that fixed the few quarks i had.
I've restarted about six times, each time to get the lights to come on I have to disable automatic brightness.
