iPhone 6 Plus Lightning Connector and Headphone Jack Cable
After fixing my headset jack successfully, people could not hear me clearly on the mic. I took it apart again today. The clip that holds the mic in place, next to the jack, had been put down too tight to the mic, which kept it from moving enough to pick sound up clearly -- everything was muddied. I only had to pull the case open a little, unscrew the mic assembly to loosen it, wiggle it back a bit, move the mic a little to align it better with the hole, and then tighten it back down. It works beautifully now and everyone says I sound better than ever. A really easy fix, but it could have been avoided if there were instructions on putting everything back together or at least tips for little things like this.
