Has your iPhone suddenly stopped working? Are you tired of people telling you they can not hear you? Do your recorded videos have poor audio quality? Probably, your iPhone's microphone has an issue. If you do not know what to do about your microphone, you can visit a reputable cell phone repair shop in Vancouver and let them fix it for you. If you want to try fixing your microphone yourself, you should test your iPhone's microphone first to find out whether the issue exists or not.

How to Determine a Fault with Your iPhone's microphone?

iPhone models, including iPhone 12/iPhone 12 Pro, iPhone 11/11 Pro/ Pro Max, iPhone X/XS Max, iPhone XR, iPhone 8/8 Plus, come equipped with three microphones, one each at the top, rear, and at the bottom. To check your front or rear microphone of an iPhone, you need to record two quick videos using the Selfie and Back Camera to check the clarity. For the microphone at the bottom, open the voice memo app (application) and capture a voice note while holding your iPhone close to the mouth. If you hear a distorted voice, you need to fix your iPhone microphone.

A Step by Step Guide to Fix Your iPhone Microphone

Here are four steps that can aid you with fixing your iPhone's microphone:

Step 1: Clean the Microphone Using a Toothbrush

Your iPhone microphone might have dust particles affecting the voice output. You can use a clean toothbrush to clean your microphone to help you get rid of the dust from your iPhone.

Step 2: Disconnect Bluetooth Devices

Sometimes, the connected Bluetooth devices are the cause of poor or no audio. For instance, your wireless earbuds may automatically turn on and connect with your iPhone if your Bluetooth remains open. It can also occur if your iPhone is connected to your car's Infotainment System. It would be best if you manually disconnected Bluetooth devices from your iPhone.

Step 3: Disable the Noise Cancellation Feature While on Bed

The ambient noise gets reduced with the default enabling of your Phone Noise Cancellation. You should disable this default feature while you talk to someone lying on the bed.

Step 4: Enable Microphone Access for Third-Party Applications

If you encounter problems attending calls using FaceTime, Skype, or WhatsApp, you may not have enabled these apps' microphone access. Go to iPhone SettingsàPrivacyàMicrophoneà Enable Microphone Access for relevant third-party apps you are having problems with attending calls.

What Else Can Be Done?

If any of the above four steps do not work for any reason, you should reset all of your iPhone settings with Factory Settings. Go to iPhone SettingsàGeneralàResetàReset All Setting Options. You should also update to the latest release of iOS if you think any recent software updates affected your microphone's audio quality.


If you have microphone issues in your iPhone, it is better to contact a cell phone repair service in Vancouver. But before doing that, you can test your three microphones to determine if something is wrong with them. The following solutions may help you recover your audio quality:

  1. Clean your microphones using a toothbrush.
  2. Disconnect the connected Bluetooth devices from your iPhone.
