I put my phone on the charger like I do every night. It was charging. Then when I woke up My phone screen was black. It wouldn't turn on. So I unplugged it thinking that maybe it died on the charger and it just stopped charging in the middle of the night. I took out the battery for 5 minutes thinking that it would maybe conduct some type of charge. I put back in the battery and tryed to turn it back on and it would not work. I don't know what to do. My phone has everything important to me on there. How can I fix it?
