Clean microphone grills

First, we recommend you check the microphone grills. Over time dirt and other debris can accumulate in the mic holes, thus blocking any sound and giving the impression that it doesn't work. Before proceeding to other methods, try to clean the mic holes.

Take a small precision tool and try to take out all the dirt from the microphone. If you're afraid of damaging your microphone, you can take the iPhone to an authorized service center for a professional cleaning.

Also, make sure your iPhone case doesn't block the mic.
