Well my main (back) camera works perfectly fine. When I try and switch to the second camera, the button to take the picture is there, but the screen is black. The screen then freezes and I have to hit home to get the black screen to go away. When I get back to home and hit the camera icon it just stay's at home screen. Leaving me to turn my phone off then on to get the back camera back...Anyone got some advice on what the problem is? Thank you.
