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.
Apple has released a preview of iOS 11.3 and all its upcoming features for iPhone and iPad users. iPhone X owners this spring will be able to express themselves as a lion, bear, dragon or skull as Apple introduces 4 new Animoji bringing the overall total to 16. iOS 11.3 will also deliver ARKit 1.5 to developers. The new toolkit will allow AR apps to recognize vertical surfaces and map irregularly shaped surfaces like circular tables, according to Apple.
