When a MIC is Really bad

It is not difficult to tell if a phone’s mouthpiece is faulty, whether for MOS or android phones. It simply won’t record sounds or allow the receiving end of a call to hear what you say.

In some android phones, there are two mouthpiece. The upper mouthpiece in the panel of the phone for sound recording and the bottom mouthpiece for forwarding sounds during calls to the other end. If the bottom MIC is damaged, sounds can be successfully recorded and heard when played, but the receiver of a call wont be able to hear what you say.
