Microphone not working

[rstem63]

I couldn't find anything posted for my specific problem. My phone got wet and I dried it out after a quick soak in alcohol to draw the water out. Got it working again but the onboard microphone doesn't work whatsoever. Makes calls and can hear the other person but they can't hear me. I can only use it on a bluetooth or plug in headset. I cannot find anything showing where the microphone is on the circuit board. I would imagine it corroded inside from the water since it has a magnet in it. Can anyone help me out with a picture of where it is located and maybe where I can get a microphone. I can solder if it uses regular solder not the new SMD solder.
