Apple has responded to a microphone issue affecting some iPhone 7 and 7 Plus units with a new service guide. The document obtained by 9to5Mac also mentions that out-out-warranty devices may still be able to receive a repair or replacement for free.
The document shared with AASPs states that some iPhone 7 and 7 Plus users may experience mic failure after updating their phones to iOS 11.3.
Users may see that the Speaker Button is grayed out during calls. Other indications of the problem is no audio during playback for voice memos or videos created by the afflicted handsets.
Troubleshooting steps include disconnecting any Bluetooth or other audio accessories and running audio diagnostics.
