so i dropped my phone on the floor by accident and the battery popped out, once i put it back in it worked again, but about 20 minutes later it froze and shut off. I was able to turn it on but in the middle of turning on it froze and shut off again. i tried taking the battery out and putting it back in and that didnt work. i tried charging it but it doesnt show that its charging. It has been plugged in for about 5 hours now but it still wont turn on. what can i do to try and fix it?
