I've had the htc desire c for about 3 or 4 months. I dropped it a couple weeks ago and the screen is cracked, but it's been working fine ever since. It was charging just now and I pressed the power button to unlock it again and it didn't work. I took out the battery and (this is bizarre...) for about 20 secs after I pulled the battery, it was still showing the "battery charging __%..." page with the green battery filling up. With no battery in the back! After 15-20 secs it shut off. I put the battery back in and the charging screen came up again. But tried to turn the phone on and nothing worked. Tried holding volume down and pressing power, held power for about 30 secs, nothing is working... HELP!!!!
