Ok so I had my phone on the charger and when I woke up I grabbed it to see the time and my phone was super hot and apparently had turned off so when I tried to turn it back on it tried to come on but then the screen just went black so I took the battery out for a minute or so and put it back in and it still wont turn on so now I have it sitting out with the back off and the battery out. Is my phone just completely messed up or will letting it cool off fix it? What do I do to fix the problem?
