Phone problem , no sound from mic?

[Defender]

when making a call on my M500 people cannot hear my voice but I can hear them ok < is mic goosed(u/s ) or is there a problem with rom ?

[docnas]

i had that probelm on my Imate Jam initially thought the problem was with the mic, after showin it to a pro he checked it out and found out that the actual cause was some chip inside which was screwing up

the microphone he tried changing twice but it made no differance to the sound

but another person once told me that theres this little rubber around the mic that holds it in place that sometimes moves and covers the mic hence no one can here u not sure if that can happen in urs but its still an easy option compared to a dead/dying chip

Is there any hardware repair disscuss in this forum?

Or better, can some one share hardware schema XDA or DOPOD?

Is that illegal ?

Hence I never see any service manual/schematic here around.

thanks
