How to Fix iPhone X/8 Mic Not Working on Calls

Method 1: Remove any Covers/Cases from Your iPhone

In many cases, the primary cause of iPhone mic not working properly is the case or cover that you have installed on the device. It could be interfering with the microphone on the device and you are not properly audible to the person you are talking to.

With that said, remove any official or unofficial covers or cases from your iPhone X/8 and then try to make a phone call to someone. If you see any improvements, then the cause of the issue was the cover and you are suggested not to use it again with your device.

If the mic sound is far away on your iPhone, you can try disabling a feature on your device to see if that resolves the issue for you. The feature that you‘re going to disable is called phone noise cancellation that cancels the noise while you are talking to someone on your iPhone.

Open the Settings menu on your iPhone and tap on General followed by Accessibility.

Now that the feature that deals with your mic has been disabled, you will find some improvements in phone call conversations on your iPhone X/8.
