Got the edge on release day and everything was fine. Updated everthing, still fine. A few days later screen doesn't rotate. Reset phone yada yada. After researching and it being a somewhat common issue I returned it to sprint with no problems. I updated to the 64 gb over the 32 and everthing seemed good for 5 days. But then.......sure enough same stupid issue. Fast charge, bad chips, gremlins....I don't really care. Samsung needs to take responsibility and at least send out apologies and tell us they are working on a fix. Reminds me of x box red ring issue yet much quicker breakdown and no response to problem. I will return and get a 3rd unit and cross my fingers. Seems this one should've been caught during the testing phase.
