I own a Samsung S850 camera and I am having problems with it's mode dial. When I switch modes it goes from mode to mode at random and half of the modes go straight to Auto. Is there anything I can do to correct this issue or does it probably need service. I have created nearly 24,000 pictures and videos in the two years I have had the camera as photography is a major hobby of mine so I understand this could be wear, but it is the only problem I am having with it. Any help with this issue would be appreciated.
