I was watching a video someone sent to me and doing some surfing as well. As it was reaching 26 percent on the meter I decided to call it a night and put the phone on the charger it was really warm in my hand. After about 20 minutes or so of charging, a text came through. I touched the top of the phone to wake it up. And it locked up no screen. After gently prying open my body glove case( the right side of the phone by volume control is really thin) popped the battery out then back in and it came back on. Anyone else see locks up when phone is hot? This is the second time it locked up with a warm phone.
