The camera cybershot on my mobile phone is not working. When i open up the camera application and the lens cover the camera comes up but the screen is black. When i go to take a picture the flash still goes off but no image is captured as the lens doesnt seem to be picking up anything it is all just black.Has anyone else had this problem with this phone and is there anyone who knows what is the problem here and how i can go about fixing it? Thank You!
