Hi IFIXIT Team, I am not quite sure but it seems like the LG G5 has a top and bottom microphone. I assume that in my case the top microphone broke as every time when I switch to face-calls the other side can’t hear me. The moment I go back to normal call everything is fine. While the web is flooded with examples how to replace the bottom microphone I couldn’t find a single example on how to fix / replace the top microphone. Do you have any advise where to look at or how this can be done?
