It was working fine, then 2 minutes after I put it down it looked like it was restarting, but then got stuck on the white Verizon screen; I took the battery out for 15 minutes, put it back in and now it's stuck on the black LG Android screen. It's very hot to the touch and just isn't coming to. Please help! I don't want to have to do a hard reset because I don't want to lose all my media. Anyone? Thanks in advance!
