How to fix your microphone problems on Android phones

Let’s admit it, Android mic problems aren’t uncommon. Having microphone problems on your Android is definitely one of the most annoying things that a phone user can experience. Isn’t it frustrating when you’re in the middle of a call and suddenly all you hear is static? What if it was an urgent business call? What if it was a phone interview?

The cause can be either software malfunction or hardware damage. Inspect damages to your phone. Did you drop your smartphone recently? Did you install apps that can potentially affect your mic? If you didn’t do either of these things but are still experiencing problems, don’t worry. I have tips on how to fix your microphone problem on Android.

Causes of Android mic problems

There are various causes on why your phone’s mic is not working. Let’s look at a few of them:

  • Sound hindrances. Check if there are any obstructions in the microphone. (It’s possible that your mic glitch could have a build-up of dirt. When was the last time you cleaned your phone?)
  • Software upgrades.
  • Third-party apps.
  • Hardware problems

I made a guide for you to follow down below. Fixing the mic problem on your Android phone is surprisingly simple. Following the steps below could save you a lot of time and money and help you avoid paying for a technician.

Side note: To check whether your microphone is working fine after each quick fix, use your recorder or do a test call to a friend or family member.

A step-by-step guide to fixing your mic problem

1. Do a quick restart

If you haven’t restarted your phone in a long time, now is as good a time as any. Restarting your smartphone clears any open apps, and can possibly be a quick fix to your problem.

Turn off your phone and wait for about 10-30 seconds before turning it on again. The process will refresh your system. Check to see if the problem is solved.

2. Clean your microphone with a pin

This mic fix on your Android phone is simple, yet it’s super helpful. Your phone accumulates dirt from using it for extended periods of time.

Mobile phones are vulnerable to dust or small debris, and can get into the small openings of your phone. You might not know it, but tiny fabric pieces can get stuck, especially if you’re always carrying it in your pocket.

Gently poking and cleaning the mic on your Android phone might fix the problem

Your mic is a small hole beside the USB connector. You can either blow at it directly or get a small pin or a thin needle and carefully poke the hole to remove any dirt inside.

3. Disable the noise suppression

Some Android phone releases come with a cool feature called noise suppression/noise reduction. It reduces the background noise when you are on a call or recording a video.

However, this can be a cause of why your microphone is acting up.

  • Go to Settings.
  • Select Call Settings.
  • Look for the Noise Reduction option and disable it.
  • Restart your phone and check if the problem is solved.

4. Remove third-party apps

Some applications can cause your phone to malfunction. They can sometimes interfere with your phone and users might experience minor anomalies.

Run your phone in safe mode to disable all third-party apps temporarily. Try a test call or use the recorder to check the microphone.

If it is working fine, then the culprit is within your apps. You can check the apps that are using the microphone by going to Settings -> Apps -> App permissions -> Microphone permissions.

Check apps that use the microphone

You can try checking each app one by one, but that can take time. If you want a quick fix, you can back-up your phone to retain all vital information and do a factory reset.

5. Use one microphone at a time


You might not notice it, but you might have connected your phone to a Bluetooth device that has its own mic. Be sure to disconnect your phone from other devices and do a quick restart.

6. Force stop Bixby Voice

Are you a Samsung Galaxy S9 user who is experiencing the same problem? It could be because of the Bixby Voice.

Open your phone’s settings and tap Apps. From there, select Bixby Voice, choose Force Stop and check if the problem is solved.

7. Install Phone Doctor Plus


Phone Doctor Plus has a toolkit that will let you test your earphones and microphone. It is multi-patent, and it has real system information, functions, and can check about 30 smartphone hardware items.

If you don’t get the results that you’re looking for, I strongly recommend that you do not try opening your device yourself. It will be better to get someone who knows what they’re doing. A friend might have advised you on a “quick fix” that can solve your problems by taking your phone apart and doing everything yourself but that might just do further damage.

Let the experts do it for you. If you have recently purchased your phone and it is still under warranty, make the most of it. Go to the nearest shop and have a professional handle the problem.
