Dear All, I have had my Samsung Vibrant for almost 8 months now, and it has been working perfect. Today suddenly i stopped getting in-call sounds, the caller can hear me but i cannot hear the caller. Prior to the problem the only thing i installed was TuneIn Radio from the market, and was using my headphone to listen to the radio. If i plug in the headphones or use speaker phone i am able to hear the caller. I would greatly appreciate any help or direction as to what could be the cause either hardware or software related.
