This morning I put my Optimus V in my pocket as I got out of bed and then stumbled a little and hit into the bed post right on my pocket where the phone was. When I pulled it out, and tried to turn it on, the screen was all white. I removed the battery and rebooted it and it boots fine and seems to be working except the screen is all black now. Have I ruined the phone? Is there anything I can do about it?
