Everything seemed normal with the phone today, no problems or anything. It was sitting on the table for a while this evening and she went to use it and it wouldn't wake up. She tried turning it on to see if it got shut off and still nothing. It doesn't seem to be charging either as nothing happens when it's plugged in. Any ideas as to what's going on and how to fix it? Already tried pressing and holding power, volume down, and home which didn't work.
