[AC Question]

OK all, so my note 2 main mic is not working.

when i call or get a call they can not hear me until i put the phone on speaker.

Speaker is working fine and when i press "speaker they can hear me fine. when i go back to handset they cant hear me.

I took it to a shop and they replaced the board that has the mic and the usb charging port on it but im having the same issue.

can anyone help?

Welcome to Android Central! Do you know how extensively the shop tested the phone before they replaced the hardware? Can you see if there is any debris lodged in the phone mic opening? If the opening itself is blocked, then changing the hardware isn't going to do anything.

It could also be a defective headphone jack. (Plugging an handsfree disconnects the internal mic, so if the jack is defective, or a wire to it is broken, the mic could be disconnected.)

As B. Diddy implied, the shop did a sloppy (to say it in the nicest way) job.
