My phone has been acting funny for the past week or so. Won't hold a charge, and the charge it does take drains VERY quickly. Today, however, the phone shut down on it's own and would not reboot. It goes to the Samsung icon screen and then would go immediately to black screen. I tried a factory reset, but when I got to that screen I was looking at a 'dead bot' with a red exclamation mark above it. I've tried the factory reset and the sytem reboot from the same screen. I now get to the homescreen for about 4 seconds, then it shuts down again. The setup wizard attempts to start and then the phone just powers off. The phone has no damage.... physical nor water. Oh, also, it's showing a full 100% charge, but when it restarts itself it shows an empty battery icon on the screen before it goes to black screen. I need this fixed asap, please help!
Thank you in advance!
