So yesterday I sit my phone down for a few minutes, and when I picked it up and hit the home button, nothing happened. I tapped the home button a few times, then pressed the power button at the top, and nothing. The battery was at about 80%, so it couldn't have drained that fast. None-the-less, I plugged it in to charge, and still nothing. Thinking my phone had just up and died, I pressed the home and power buttons together for a few seconds, and then heard the sound of the shutter (desktop photo, I guess), then the phone went to the passlock screen and the phone has been fine since. Very odd. Has this happened to anyone else?
