I was editing pictures and my phone shut off. When I turned it back on it wouldn't go farther than the white background with HTC on it. Turned it off and took battery out for 2 hours. Powered on; then cut off. Tried another battery. Powered on and I got to text messages. Froze with numbers showing, not names. Shut off again; few minutes later a white screen with 3 droids skateboarding came on; won't do anything else!! HELP!!
