Mic Not Working on Android? (Do THIS First!)

If the mic is not working on your Android phone, you probably can’t communicate with your friends and family.

Microphone issues on Android devices are very common, fortunately, it’s an easy problem to fix, providing you know what to look for.

This guide walks you through several troubleshooting steps you can try to fix when the mic is not working on Android.

Why Is Mic Not Working on Android?

One of the main reasons why the mic is not working on your Android phone is because of dirt and lint that block the mic holes. Brush the microphone hole with a toothbrush with soft bristles to remove any debris that may have gotten inside.

Your Android mic can also stop working because of third-party apps hindering its access. It is possible for hardware damage to occur if your Android device falls or endures a hard impact, resulting in a malfunctioning mic.

How to Check if Your Microphone Is Not Working

If you found out that your microphone was malfunctioning through a phone call, you might need to recheck. The problem might have come from a network glitch.

You can voice record yourself to be sure your Android device’s microphone isn’t working. To do that, open the default voice recording app on your phone and recording yourself talking. If you can’t hear yourself clearly or at all, your microphone is having problems.

If your Android device doesn’t come with a voice recorder app installed, you can download one from the Google Play Store or record yourself speaking on a messaging app like WhatsApp or Telegram.

To further confirm, you can connect an external device like an earphone and speak into the mic. If your phone can recognize the sound from the mic of that device but not from the phone itself, there is a problem with your Android microphone.

Clean Your Phone’s Microphone

Dirt, dust, and lint can clog your microphone and stop sound from getting to it. If you do not clean your phone regularly, this build-up can cause problems for you.

To clean your microphone, switch off your device, get a pin, and gently use it to clean the microphone. Try to get out all the dirt. The microphone is located at the bottom of your phone right next to your USB charging port.

If you decide to blow into your mic to clear it instead, be careful not to blow the dirt higher into the hole. Cleaning with a pin or needle is the best fix.

You can also use a soft brush to gently clean the mic and other holes at the bottom of your device.

Cleaning your device will get your microphone working again.

Check if Your Mic Is Covered

If you recently got a new phone pouch or screen protection, check to make sure that they do not cover your device’s mic.

Take them off and try using the microphone. If it works, you need to make a hole or provisions for sound to get into the mic.

Check For Connected Devices

Most times, we forget that our phone is connected to a Bluetooth device. If your phone is connected to a Bluetooth mic or speaker, you might be unable to communicate with people using your device’s mic.

Turn off Bluetooth to disconnect your phone from all devices and then restart. Try using your mic now. It should be working fine.

Check For the Headphone Symbol

If you use earphones or a headphone, sometimes your Android device does not register when you unplug it.

This will stop your microphone from working because your phone thinks it is using the headphone’s mic.

Fixing this is easy. Just plug the headphones back into the jack and remove it after a few seconds.

Your mic should be working on your Android device now. If it isn’t, try the next step.

Check for Interference From Third-Party Apps

Third-party apps are applications that do not come installed on your phone from the manufacturer. Sometimes, these devices malfunction and can stop some parts of your phone from working properly.

Run your device in Safe Mode to check if your mic works without the third-party apps. Safe Mode disables all third party applications.

  • Press and hold the ON/OFF button at the side of your Android device.
  • When the menu pops up, long-press the Power Off button.

  • Click on Safe Mode.

Your device will restart itself and boot with only apps from the manufacturer installed. There will also be a box with Safe Mode written in it at the bottom of your screen.

Now, check if your microphone works. If it works fine, then the third-party apps are to blame for the problem.

To fix the issue, you will need to carry out a factory reset on your device. This will wipe all your data so be sure to back up your information before resetting.

If you do not want to reset your device, you disable microphone permissions for all third-paarty apps one by one. It is a slow process but is the best alternative.

Disable Microphone Permissions For Third-Party Apps

To disable microphone permissions, follow these steps:

  • Go to Settings and click on Apps.
