When i first got my tab at the best buy exclusive I didn't have any problems with it with the exception that the auto brightness was constantly adjusting so dramatically to the point where it even looked like the screen was flcikering and it would get so dark i could not see it. So i ran a reset very quickly and i've never had the problem ever since. It's not like they test the functionality of every tablet when it comes from the factory. I think they should make it standard that the day you take it out the box and start it up for the first time that it runs an automatic reset or something, just to make sure everything is functioning cause it sucks to start using it and have to all set up to realize that you need to run a reset to have it optinmal.
