I got a new Galaxy S6 four weeks ago. I set the phone down for an hour and when I picked it back up it was off. 30 seconds after turning it back on, it claimed that the device was overheating and that it needed to turn off to cool down. I tried rebooting it several times, but the problem didn't go away, so I factory reset it. The problem is still persisting, and I can't even get through the setup process before the phone claims that it is overheating and shuts off.
