I would HIGHLY recommend not attempting this fix. I have done a variety of repairs on iPhones (screens, batteries, etc.) and decided to try this to address a broken microphone. I could make regular phone calls but couldn’t use speakerphone or FaceTime. After replacing the lightening charger using the instructions and the iFixit parts, I still can’t use the speakerphone or FaceTime function. To make matters worse, my phone won’t charge through the lightening connector, won’t wirelessly charge, and people can’t hear me even when I make a regular phone call anymore. In other words, I started with one fairly minor problem and, due to this repair, have a whole bunch of new (much more significant) issues. Don’t make the same mistake I did.
