Detailed Steps to Turn On Microphone On iPhone

Many applications use your iPhone’s microphone. From the camera app to Siri, to FaceTime, all these apps require the microphone to function properly. While system applications can access your iPhone’s microphone by default, third-party apps require user permission. 

If your microphone won’t work with a specific app or it doesn’t work in general, we’ve got you covered. This guide will assist you in enabling the microphone on your iPhone. 

Enabling Your Microphone for Specific Apps

Here’s how you can enable your iPhone’s microphone for a specific application: 

  1. Open the Settings app from your home screen. 
  2. Scroll down and access the Privacy & Security tab

If the toggle switch beside an app is gray or set to “Off”, then that app can’t access your iPhone’s microphone. 

Enabling Microphone Access For Siri

Check out the steps below to enable microphone access for Siri on your iPhone:

Adjusting Microphone Volume

While iOS doesn’t have a direct option to adjust microphone output, third-party applications like Discord support this option.

If you’re using an external mic with a dedicated app like the Hollyland Lark M2, you should be able to adjust different settings like microphone output and noise cancellation levels.

Troubleshooting Microphone Issues on iPhone

Here are some general troubleshooting tips in case you encounter problems with your iPhone’s microphone: 

1. Check for Obstructions

If your microphone sounds distorted or muffled, it might be obstructed by third-party accessories. It’s also possible that dirt has built up around the microphone hole, preventing sound from passing through. 

Find the microphone hole on your iPhone and make sure that it’s not covered by your protective case or screen protector. 

You can blow through the microphone to remove dirt and debris or use a soft brush to clean it. 

2. Restart Your iPhone

Temporary errors can occur on your system, causing your iPhone to lose some functionality. If your mic doesn’t work, perform a system restart to reload iOS and resolve errors that occurred during runtime. 

If your iPhone has FaceID: 

  1. Press either of the Volume buttons together with the Side button until the “Power Off” slider shows up. 
  2. Drag the slider to the right until your screen turns black. Wait for 30 seconds. 
  3. Press the Side button once to turn on your iPhone. 

If your iPhone still uses TouchID: 

  1. Press and hold the Side button until the “Power Off” slider appears. 
  2. Drag the slider to the right until your screen turns black. Wait for 30 seconds. 
  3. Press the Side button once to turn on your iPhone. 

Try recording a voice memo afterward to check if your microphone works. 

3. Update iOS

Apple continuously releases new versions of iOS, which contain improvements and bug fixes. The version of iOS you’re using might have an issue that is related to the microphone and an update might help fix it. 

Here’s how you can update your iPhone: 

  1. Open the Settings app on your iPhone. 
  2. Go to the General tab. 
  3. Tap on Software Update.

  • Make sure your iPhone has over 50% charge before installing an update. 
  • Your iPhone might appear stuck during the update. Do not turn off or restart your iPhone while an update is being installed. 
  • Software updates usually take between 5-8 minutes to install but could take longer depending on the update size.

4. Reset Your iPhone’s Settings

Conflicts with your system preferences and settings can also cause your iPhone’s microphone to malfunction. Try resetting your settings to ensure your iPhone’s configurations are set to default. 


Resetting your iPhone’s settings will not erase your data but will reset system settings, including Wi-Fi passwords, wallpaper, etc. 

  1. Open the Settings app on your iPhone. 
  2. Go to General > Transfer or Reset iPhone > Reset
