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.
Concerns over privacy may come and go, but Apple always has your back. The iPhone, iPad and iPod touch have built-in features designed to protect your data. iOS offers several options to control which apps have access to the hardware on your device. Apps such as Facebook are widely suspected of eavesdropping on conversations. Whether this is true or not, there's an easy way to check which apps have permission to listen using the on-board microphone.
