Caller can't hear me after port change

I've changed the charging port on a 6s and when I checked it everything was working as it should, now the mic has stopped working on calls. I can be heard when in loud speaker and hands free only, there was a metal shim on the mic at the right of the port that I couldn't get off the old one so I hadn't replaced it. Could this be causing the issue?

I recommend testing the charging ports before install, most functionality coming from it if possible.

Sounds like a faulty charging port (main microphones on the port not working). I suppose it could of went faulty from being improperly installed (tear in ribbon cable / puncture).

I have replaced them before, but not really sure what metal shim you are referring to.

Are you referring to this in step 46:

iPhone 6s Lightning Connector Assembly Replacement

There is black tape covering a screw hole for a metal cover for an antenna cable.

Hi, thanks for your response. I've done loads of charging ports and never had an issue before, if you look at step 55 there is a spudger on the mic with the metal shim which was missing on my replacement charging port.
