I've had my mytouch 4g for a little over a month now and it has not been dropped nor water damaged but whenever i try to open the camera app or camcorder app the screen goes black and stays like that until i exit. i have tried a factory reset, ive "force stop" the camera app and restarted my phone, and ive even tried to download another camera app to try to use, but to no avail. everything else works fine. please help me figure out what the problem is....thank you.
