8 fixes to iPhone microphone not working

Here are some effective fixes to address microphone on iPhone not working issue. Try them one after another, until your issue gets fixed.

1# Clean up the microphones

Carefully inspect and clean all microphone ports. Your iPhone has multiple microphones:

• Bottom Microphone: Next to the charging port.

• Back Microphone: Near the rear camera for video recording.

• Front Microphone: Integrated into the speaker grille at the top of the screen.

How to clean: Use a soft, dry, clean brush (like a new toothbrush) or a blast of compressed air to gently dislodge debris. Never use sharp objects or liquids.

2# Test the microphone on your iPhone

The problem of your iPhone microphone not working might be related to the app you use for phone calls or voice recording. To determine if the microphone is truly not functioning, you may need to confirm it after cleaning up.

Step 1. Open the Voice Memos app.

Step 2. Tap the red record button and speak for a few seconds.

Step 3. Tap stop and play it back.

• If your voice is clear: The hardware is working. The problem is specific to another app (like Phone or FaceTime).
• If there's no sound or it's distorted: The issue is system-wide or hardware-related. Continue troubleshooting.

3# Force restart your iPhone

When your iOS devices encounter issues and aren't functioning properly, performing a force restart can often help resolve the problems. If you're fortunate, the microphone for iPhone not working might disappear after a factory reset. Depending on the specific model of your iPhone, follow these steps to do a factory restart:

4# Check app permissions

If you're experiencing microphone issues in specific apps that require microphone access, the problem could be related to app permissions. When an app wants to use your device's microphone, it requires your permission to do so.

If you haven't granted these permissions, that could be the cause of your microphone not working problem. To address this issue and resolve the iPhone microphone issue, follow these steps to grant the necessary permissions to the apps:

Step 1. Head to the Settings app on your iPhone > Locate and tap Privacy > Choose Microphone.

Step 2. Ensure the toggle is ON (green) for the problematic app.

Step 3. If it was off, turn it on and retest the app.

5# Update iOS to the latest version

Ensure that your iPhone is updated to the latest iOS version. Software updates often include fixes and enhancements that could potentially resolve microphone problems.

Step 2. Click on Reset All Settings > When asked, enter your password > Tap Reset All Settings again to confirm.

7# Diagnose and Repair iOS System Issues

If your microphone stopped working after an iOS update, or if problems persist despite all other fixes, the core iOS software may be corrupted. In these cases, standard resets may not be enough.

Software like FoneTool Repair is designed to diagnose and fix such complex software problems without leading to data loss in "Standard Repair" mode.

8# Contact Apple Support for Hardware Repair

If none of the above software fixes work, and your microphone consistently fails in all apps (Phone, Voice Memos, Camera video, Siri), you likely have a hardware failure.

• Schedule a repair via the Apple Support website.

• Check for coverage: See if your iPhone is still under the standard one-year warranty or AppleCare+.

• Common hardware causes: A disconnected internal flex cable, a damaged microphone component from impact, or liquid damage.
