by Jenefey Aaron   Updated on 2019-08-30 / Update for  Fix iPhone

iPhone X and iPhone 8 are Apple‘s latest offerings bringing advanced technologies to their users. But with more features comes more issues and these phones are no exception. Some users of these phones complain that the microphone voice is too low when making calls while others say the iPhone mic doesn‘t work during calls at all.

If you‘re facing any such issues with the mic on your iPhone X or 8, you might want to follow the below methods to solve them.

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.

Method 2: Disable Noise Cancellation on Your iPhone X/8

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.


When the Accessibility screen opens, find and turn off the feature that says Phone Noise Cancellation.

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.

Method 3: Change LTE Settings on Your iPhone X/8 to Fix Mic Issues

Some users suggest that changing a settings option related to LTE will fix the iPhone mic not working issue and the following shows how you can do that.

Launch the Settings menu on your iPhone X/8 and tap on Cellular followed by Cellular Data Options.

Tap on Enable LTE and on the screen that follows, choose the option that says Data Only. You can tap on the option and it will get selected.

The issue could be with the software on your device and repairing the OS will fix it for you. The following is how you can use Tenorshare ReiBoot to repair the OS of your device.
