I've had my Nexus 7 since July and I've been completely satisfied with it. Once I got the 4.1.2 update some strange things have been happening and I'm trying to pin down the reasons since it seems to be a software issue and not a hardware one. The first event happened when I was trying a Live Wall Paper, Oceans HD. After setting the LWP and using it for a few minutes the next time I picked the tablet up and tried turning it on I noticed it had reset. No problem, except after the splash screen everything would go dark again and the power button didn't seem to work at all unless I waited for a while, and tried long pressing it and rebooting the device. After a few reboots of this the screen began to behave weirdly, sort of looking as it there was a problem with the video driver since it looked like a an old TV screen with static. I thought the video hardware was toast and was relived the next day when I tried to reboot again that the tablet rebooted to the default WP. No problems after that. I contacted the maker of the LWP thinking that was the problem. However, after trying out another LWP from another maker, the same thing happened after a few days of use. Jumped through the same hoops and got the WP changed to a static one. I went online and read through a few forums to see if anyone had the same problems but was not bale to find the same issue. I read something about the auto brightness and turned my auto brightness off to see if that works. What do you guys think about this? I use the tablet a lot and for professional purposes often. I cannot afford to have it go bonkers during a presentation.
