Apple admits: There are problems with the handset of some iPhone 7/7 Plus phones

MacRumors discovered through the leaked documents that Apple admitted that some iPhone 7 and 7 Plus running iOS 11.3 or later may have a bug that the microphone will not work during the call. A few users of the affected devices are passing FaceTime. You may see their speaker buttons grayed out when you make a phone call or video chat. This issue seems to only affect phones running iOS 11.3 or later.

Some users of Reddit and Twitter have reported problems with such microphones in the past few months. The leaked documents were sent to an Apple Authorized Service Provider. This clearly confirms that Apple has learned this problem.

Apple recommends that the technical support staff tell the user to unpair or close any Bluetooth devices and accessories connected to the iPhone. If this does not work, it is recommended that the technical support staff run the audio diagnostics, which is done via an alert message (such as 'does not support attachments' or ' The device can't detect the cradle ' ) to diagnose if the phone needs repair. Once an alert message appears, technical support can repair the iPhone. MacRumors stated that the file does not clearly indicate a software or hardware issue.

IT House learned that even if the mobile phone has a warranty period, the genius of Apple's genius will help solve the problem, but whether the free price is still unknown (foreign media 9to5Mac reports that it is free).
