I have the same problem, my mom got the same phone as me at the same time as well, and her phone doesn't do it, i sat for a long time trying to get her phone to do it and i couldn't get it to do it, meaning its a hardware problem, and my phone would still do it even after i hard reset it, it did it in the little Google account setup login, if i get a new one its possible the replacement will do it, and I also don't want a refurbished phone. im so lost on what to do... i friggen hate going through this crap. and dangit google didnt restore all my apps!! it put apps I don't use anymore on GAH!!!
