I've had my Samsung Galaxy Proclaim for a few months. Just last night this problem started. I can hear callers but they cannot hear me. I can still send and receive texts just find as well. The phone has not been dropped nor been exposed to water. I have tried calling several people, have had people call me and the problem is still there so I know it is on my end and not theirs. Please help... I need this fixed right away. I can't go around just texting.
