Ive just had a new iphone 4 and im having prioblems with the camera. When I take a picture, the camera shuts down without actually taking a picture. eg I open the camera, press the button to take a picture, the shutter closes and the camera shuts down, no picture is taken. Has anyone else experienced this ? even shutting the phone an restarting doesnt sovle it. This has only just started happening, it was taking picture ok before and Ive only had it a week !
