Hi to all. I have a problem with internal microphone from 9210. It does not work. I replaced it and clean pads, and same problem. With headphone works fine.
What should I do?

Thanks in advance to all.

ok, this is a good new

If you already have this phone please tell me one thing

I not found a component but I dont know what component
one 9210 can't read mmcs, all ppl tell me that the problem is the mmc cover connection to gnd but I dont see this connection, I have could lose one piece but I don't know what connects this pin...
could you tell me what is connected with mmc cover or if you know something about this mistake?

thanks a lot
