I've had my Hd7 from day one and it recently has been acting up. If I try to launch the camera sometimes it opens up and closes and goes right back to the start screen. But there are times when it stays open but it only shows a black screen and I can't change the settings or change it to video record. I have tried to use 3rd party apps but they launch the camera and then it freezes my phone and restarts it! I've resetted soo many times and im very reluctant to do a hard reset please help!!
