I have a HTC desire Hd, and a couple of months ago my camera stopped working, it would load up and have the buttons on the bottom but just a black screen. I sent it off and got it repaired through orange. But now it doesnt even load up, i click on it. the screen goes black then it quits back to my home screen? 3rd party camera apps dont work either, just says it can't find the camera? help please?
