The three buttons at the bottom on the screen on my 8000 pro went on and would not go off even after a few restarts. The entire phone eventually started warming up and eventually got so hot in my pocket. The phone was off and have not been able to switch it back on. I tried to charge after it cooled down. The bottom of the phone.gets warm but otherwise no sign of life. No lights what so ever. Unable to do a reset as well by holding in power button.
