According to some user reports, and confirmed by 9to5Mac, the release of iOS 11.3 is affecting some iPhone 7 and iPhone 7 Plus units.
Apparently, some units updated to iOS 11.3 are having issues with the microphone when making phone calls and using FaceTime. Some users say they can’t be heard, which is a serious problem, especially if someone is attempting to contact emergency services.
Apple is reportedly aware of the issue, saying it’s an extremely rare problem that could potentially be fixed. The good news is 9to5Mac claims Apple may fix or replace out-of-warranty devices for free.
A service guide seen by 9to5Mac highlights some troubleshooting options, like disconnecting Bluetooth accessories. If that doesn’t fix the issue, you may need to make a Genius Bar appointment, in which they will assess what steps to take next.
Apple has struggled with a string of bugs since iOS 11 was released last fall, and the latest issue highlights how badly the company needs to hit the reset button. With WWDC on the horizon, reports claim that’s exactly what Apple will do with iOS 12.
