So my vibrant (have it for about 6 months now) has developed a problem of no longer being able to mount the phone OR sd card to my PC. When I do the pulldown menu there is no option to mount, nothing is listed. Drives dont show up in "my computer". It does however beep and indicates its now in charging mode. Tried turning the phone on and off, tried another computer. Checked and unchecked USB debugging and Im at a loss. HELP!!! thanks all!
