How to fix Galaxy S10 microphone not working | easy ways to troubleshoot bad microphone

While rare, microphone issues do happening Samsung Galaxy devices. If your Galaxy S10 microphone is not working and you have no idea why, you must do a number of troubleshooting steps to identify the reason for it.

Microphone not working fix #1: Know more about the problem

Before you do any proper troubleshooting steps, the first thing that you want to do is to gather more relevant information about the case. By that, we mean you must you must check if the microphone issue occurs on your entire software experience or if it’s only happening with a particular application. You also need to check if there’s any error message that shows everytime you try to use the microphone function. In most cases, microphone function may simply be disabled by mistake so you must ensure that you also check that possibility out. If you were tweaking some settings immediately before the microphone became dead, try to undo what you did. Only you knows the history of your device so you play a key role in figuring out the problem.

In this case, it’s important that you also test if you can record your voice. If voice recording does work but microphone is still non-functional in some areas, continue with the troubleshooting steps below.

Microphone not working fix #2: Deal with the particular app having a problem

If the microphone only stops working when trying to use one app, like the Phone app, you should troubleshoot that app first. There may be a setting or an unknown app bug behind the problem. What you can do in this situation is to go over the app’s settings and see if there’s any setting that you may have changed that prevents the microphone from working. If there’s no such setting in your app, try to clear the app’s data to return it to its factory state. Here’s how:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the Instagram app.
  6. Tap Storage.
  7. Tap Clear data button.

Before you decide to reset the app, you can also try to see first if the issue can be fixed if you simply force quit the app. There are two ways to do that.

  1. On your screen, tap the Recent Apps soft key (the one with three vertical lines on the left of the Home button).
  2. Once the Recent Apps screen is shown, swipe left or right to look for the Instagram app. It should be here if you managed to run it previously. Then, swipe up on the app to close it. This should force close it. If it’s not there, simply tap the Close All app to also restart all apps.

Another way to force close an app is this:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the messaging app.
  6. Tap Force Stop.

Microphone not working fix #3: Restart the device

At times, minor bugs may develop when you allow your phone to run for a weeks at a time. Just like a computer, your phone may become sluggish and buggy if left turned on for too long. Make sure to refresh the system by doing a soft reset. This simulates the effect of a “battery pull,” which basically restarts the system and clears the RAM in the process. In many cases, this is enough to get rid of minor bugs. Here’s how it’s done:

  1. Press and hold the Power + Volume Down buttons for approximately 12 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Allow up to 90 seconds for the reset to complete.
  3. If Maintenance Boot Mode screen won’t show, then your device does not have it. Simply wait for the device to power down completely.

Microphone not working fix #4: Disable Bixby Voice

In older Samsung Galaxy devices like the S9, some users were able to find a workaround for a microphone bug by turning off Bixby Voice. We found no proof that this can be applied to all microphone not working issues for all Samsung Galaxy series or with the Galaxy S10 in particular but you might want to do it for a try. It can be done easily under a few seconds so it’s worth testing. Here’s what you can do:

  1. Open Settings.
  2. Tap Apps.
  3. Select Bixby Voice.
  4. Tap Force Stop.

Microphone not working fix #5: Check for rogue apps

One other possible reason why your Galaxy S10 microphone is not working can be a bad app. To check, restart the phone to safe mode. On this mode, all third party apps will be suspended so if the problem won’t occur, a bad app must be to blame. To restart your device to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If the touchscreen issue won’t appear on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S10 is still problematic, repeat steps 1-4.

Microphone not working fix #6: Reset app preferences

Like any other apps and services, your S10’s microphone function relies on some default apps and services in order to work. At times, a new app or even a user may disable a critical app causing a chain of problems. To ensure that you have all default apps and services up-and-running, try to reset app preferences on your device. Here’s how:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your S10 and check for the problem.

Microphone not working fix #7: Return software settings to defaults

If nothing has helped so far, the final software solution to try is factory reset. Doing this will delete app personal data and return Android to its factory version. This means that the entire software experience will revert to the state when you first unboxed the device. If the cause of the problem is software-related, factory reset will most likely help. Here’s how to do it:

Method 1: How to hard reset on Samsung Galaxy S10 via Settings Menu

  1. Create a backup of your personal data and remove your Google account.
  2. Open Settings app.
  3. Scroll to and tap General management.
  4. Tap Reset.
  5. Select Factory data reset from the given options.
  6. Read the information then tap Reset to continue.
  7. Tap Delete All to confirm action.

Method 2: How to hard reset on Samsung Galaxy S10 using hardware buttons

  1. If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
  2. Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
  3. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  4. Press and hold the Volume Up button and the Bixby button at the same time.
  5. While still holding the Volume Up and Bixby keys, press and hold the Power button.
  6. The Recovery screen menu will now appear. When you see this, release the buttons.
  7. Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
  8. Press the Power button to select ‘Wipe data/factory reset.’
  9. Use Volume Down to highlight Yes.
  10. Press the Power button to confirm factory reset.

Should none of the software solutions above help, there’s either an issue deep within the software (programming problem) or your phone’s microphone must have simply been malfunctioning. Since none of these things are within your ability to fix, you must visit your local Samsung Service Center for a fix.
