iPhone 7 - "People cant hear me on Speakerphone"

The microphone used while talking on your speakerphone in an iPhone 7 is attached to the charge port. Before installing the entire charge port you will want to be sure a new microphone solves your problem. In this video I plug a new port in that contains the suspected microphone and test it before undergoing the relatively major repair. It is best to test first before installing the port because it is possible to get a bad part right out of the package.
