I'm having an issue with my Samsung Galaxy S. My phone has trouble reading my internal SD card. When the problem occurs, I cannot take pictures, or even access the "My Files" folder.
When I check the settings in the SD card and phone storage area, everything is unavailable or greyed out. The phone is not USB mounted when this happens. A battery pull fixes the problem, but this seems unconventional. Also Kies does not work as well with my device.
