Hi ive had a mytouch 4g since like november and it has never gave me any problems except for now. it has three weeks turning the camera on and taking pictures all by itself no matter if im at the home screen, or anything im doing on my phone it will automatically just turn the camera on and take pictures . to get out i have to click the back button twice and it comes out again and again and again and again and then it stops. until like three minutes later it continues. the only time it doesnt switch to camera mode is when the phone is left alone and its on hold . idk whats wrong please help!
