I've got the same problem with my brigthness since version 4.2. And some of my apps are now crashing. Is version 4.2 just crap? I will downgrade as soon as possible.
Hi,
I get exactly the same problem as you with my brigthness since version 4.2. Plus, one of my apps does not work anymore (xbmc). It crashes.
Really disapointed. I think to downgrade my N7.
