How to Fix an iPhone 8 Microphone Not Working [Troubleshooting Guide]

Perform Basic Troubleshooting

Start with some basic troubleshooting steps:

  • Restart your iPhone 8. A simple restart can fix many minor software glitches.
  • Check the microphone openings. Make sure the openings along the bottom, front, and back of your iPhone are clear of any debris or obstructions. Even a small bit of dust can muffle the mic.
  • Update your iOS. An outdated operating system can cause microphone malfunctions. Go to Settings > General > Software Update to download the latest iOS version.
  • Reset network settings. Issues with Bluetooth or Wi-Fi could impact the mic. Go to Settings > General > Reset > Reset Network Settings. This will reset all network settings without erasing data.

Test Each Microphone Individually

The iPhone 8 has 3 built-in microphones. Isolate which mic is having issues:

  • Bottom microphone – Open Voice Memos and record a test clip. Play it back to check if your voice is clear.
  • Front microphone – In the Camera app, switch to the front facing camera. Record a video of yourself speaking. Play it back in Photos.
  • Back microphone – Record a video with the rear camera while speaking. Play back the clip to check the audio.

If one mic is not working properly, you can narrow down the issue area.

Check App Permissions

Check App Permissions

Make sure any app with microphone problems is allowed access:

  • Go to Settings > Privacy > Microphone
  • Ensure the problematic app is enabled and can access the iPhone microphone
  • Toggle access off and back on for the app if needed
  • Contact the developer if mic access seems correct but issues persist

Try Different Headsets or Earbuds

Faulty third-party headsets are a common source of microphone problems. Test the mic using Apple or high-quality headsets. Non-Apple accessories can have compatibility issues.

Examine for Physical Damage

Inspect your iPhone 8 closely for any signs of physical damage – cracks, dents, water exposure etc. Damage to the actual microphones or logic board components can prevent proper functioning.

You may need professional repair if there is hardware damage. Apple or a reputable repair shop can examine your device.
