First-day Verizon GS3 user here--If I just straight-up press the power button on the first try it'll almost always turn off and then flick back on immediately. Same thing when the screen is off--if I turn it on, it'll flick on and then straight off again. If I wake it with the home button, it'll turn on no problem, no flickering. Pretty sure it's hardware, given all of that. The odd thing is, I can pretty easily turn the screen off and on by pressing on the phone near the power button. Kind of annoying, and not a huge deal, but this is going to get old if I have to do this for another year. Anyone else having button problems?
