Submitted by Fred Straker on
Apple has notified its authorized service providers of a rare issue where the iPhone mic stops working during phone calls or FaceTime video. The problem happens to some iPhone 7 and iPhone 7 Plus models running iOS 11.3 or later. Devices experiencing the problem may have a greyed-out speaker button while phone calls are in progress, with the owner unable to be heard by the other party on the line. The good news is that Apple has offered a fix to affected customers.
