Apple is aware of a bug that affects some iPhone microphones during calls, according to reports.
The bug reportedly affects the iPhone 7 and 7 Plus models, and causes the phone to glitch during phone calls.
Tech website MacRumours has reported that an internal Apple document has noted that “customers may experience a grayed-out speaker button during phone calls. The issue may also prevent affected customers from being heard during phone calls or FaceTime video chats.”
Users experiencing this problem have all been using a phone operating on iOS 11.3 or subsequent versions of the software.
In a memo to Apple Authorized Service Providers, Apple said that service providers at Genius Bars should attempt to fix the issue even if the phone brought in is “no longer covered by warranty.” The memo, however, does not specify that this would be done free of charge.
Before bringing the phone in for repair, Apple has advised customers to “disconnect or power off any Bluetooth headsets or other audio accessories connected to their iPhone to see if that alleviates the problem.” If that doesn’t work then it may be time to bring the phone to be fixed.
