This morning my s3 was overheating, I tried to close the phone and then turn it off but to no avail. Then it shut down on it's own about a minute later. These are the things I have tried so far: Remove battery and sim card for awhile. Put in a new battery and tried to charge. I push the power button, volume up button and the menu button at the same time and hold. Did the 3 buttons above in a pulse pressing over and over (like cpr) Does anyone have any suggestions? Thank you.
