How To Fix A Microphone On An Android Smartphone

Common Reasons Why a Microphone Stops Working on Android Phones

Here are some reasons why the Android phone microphone is not working:

1. Dust or debris: 

    

Dust, dirt, lint, or other small particles may block the microphone opening, preventing sound from reaching the sensor.

1. Software glitch:

    

Bugs in apps or the system can interfere with the microphone's working.

1. Incorrect app permissions:

    

If an app does not have microphone access, then it won’t work.

1. Accessories:

    

Connected Bluetooth devices or headphones can interfere with your microphone settings.

1. Hardware damage:

    

Water exposure, drops, or wear and tear can damage the microphone component.

Methods to Fix Android Microphone Not Working Issues 

Use any of the methods suggested below to fix an Android microphone not working:

1. Restart Your Phone

Restarting your devices helps eliminate temporary glitches and resets the system’s processes. Switch it off, wait for a few seconds, then hit restart. Once your phone reboots, you may find that the microphone is back to normal.

1. Check the Microphone Permission of Your Phone

Without permission, apps cannot access the microphone. Check if the permission is restricted. Go to Settings > Apps > Permissions > Microphone. If not, enable it. You can also adjust app settings directly by tapping on them.

1. Clean the Microphone

Use a soft brush, toothpick, or compressed air to clean the microphone opening gently. Avoid sharp objects that may damage the mic or push the debris further inside.

1. Boot Your Phone in Safe mode

Safe mode disables all third-party and non-essential apps that may be conflicting with your microphone. Press and hold the power button, then long-press “Power off” until the Safe Mode appears. Then test the microphone. If it works, an app is the culprit. Uninstall recent apps one by one till you find the troublemaker.

1. Turn off Noise Reduction

Noise reduction settings can, at times, interfere with microphone functionality. Head to Settings > Accessibility > Hearing enhancements or Sound Settings. Toggle off noise reduction, noise cancellation, or similar options. Now test your microphone.

1. Clear App cache and Update Software

A corrupted cache, outdated apps, or software can cause microphone malfunctions. 

• To clear cache, go to Settings > Apps, select problematic apps, and clear their cache. 

• Check Settings > System > Software update for available updates.

Keeping your phone updated helps fix bugs and prevent common problems.

1. Reset Your Phone

A factory reset wipes out all data and restores your phone to its original settings. So, back up your data first. Then go to Settings > System > Reset options > Erase all data. The reset resolves deep software bugs and completely resolves any persistent microphone issues.

1. Contact Repair Service

When all other solutions fail, it means that your phone is suffering from a hardware defect. Contact your manufacturer’s authorised service centre to check and repair a damaged microphone or other components.

Conclusion

Microphone issues can be frustrating, mainly because they interfere with basic phone functions, such as making calls, sending voice messages, and participating in online meetings. If the microphone on your Android phone is not working, you can fix it easily through simple steps like rebooting your phone, checking for permissions, or cleaning the mic. For more complicated situations, you can switch to safe mode, update the software, or adjust the settings. 

A factory reset is your last resort before asking for professional help. The next time you encounter microphone issues, try these solutions step by step. With basic troubleshooting, you can have your mic working again.
