    So ... does it work with other things, or with nothing?

    If it doesn't work at all, the mic may be shot. (Ir a wire to the mic may be broken or ... a few things. It would have to go into a repair shop.

    If it only doesn't work for the phone, but works for other things, it could be the Phone app (you can download another dialer and make a call) or something in the firmware may be corrupt - and you'd have to reflash it (or bring it into a repair shop and have them do it).

    Welcome to Android Central! If people can hear you when speakerphone is off, then it could also be a problem with the secondary mic at the top of the phone (which is typically used for speakerphone). Make sure that mic isn't blocked (e.g., by a case or by lint clogging the opening).
