How to Clean iPhone Microphone

If your iPhone microphone is not working or if it seems like people can't hear you very well, the issue could also be that the microphone port has collected dust and needs to be cleaned. You can do this fairly easily using a dry toothbrush or cotton swab.

Where is the microphone on iPhone? The iPhone has three microphones in total. Depending on which model you have, your iPhone might look a bit different than the diagrams below. However, the approximate location of the iPhone's three microphones is generally the same across all models as far back as the iPhone 8. The first is found to the left and right of the lightning port at the bottom of the phone. You’ll see two cutouts that house both speakers and the bottom microphone:

The second microphone is found at the top of the phone in the speaker grill:

The third microphone is found on the back of the phone. Depending on which iPhone model you have, the exact location might be a little bit different, but it will always be near the camera lenses:

Once you’ve cleaned the microphones, you can put them to the test by making a phone call or taking a short video clip.

Cases Can Block the Microphone

If you use a case with your iPhone, it could be blocking the microphone, making it harder to pick up sounds. Try removing your case, then test your microphone by making a phone call, using voice memos, or recording a short video. If your microphone seems to work better without the case, you may want to invest in a different phone case.

How to Change iPhone Microphone Settings

If you’re only having trouble with the microphone in a specific app, the issue might simply be your privacy settings. The iPhone offers privacy options to keep apps from listening to your microphone, so if the setting is turned off, the microphone won’t work in certain apps.

  1. Open the Settings app.

    Open the Settings app.
  2. Scroll down and tap Privacy & Security.

Hopefully, one of the above solutions worked out for you. However, if your iPhone microphone is not working even after trying all of the steps we suggested, then you might be experiencing a hardware issue. If that is the case, you will need to contact Apple Support or visit an Apple Store for further assistance. Next, find out how to fix your AirPods mic not working!
