  • Rule out any third-party app

Sometimes the problem can be down to a third-party app that you may have recently downloaded or if you performed an update, this could be a cause. You can test this by running the Samsung S9 and S9 Plus by running the phone in Safe Mode, which will block all third-party apps. If the microphone works in Safe mode then uninstall third-party apps one by one in normal mode. Start with the ones you installed recently, and test the microphone every time you remove an app until you identify the cause.

To boot into Safe Mode:

  1. Press the power button and tap the option to turn off the phone

  3. Pay attention while the phone is booting!
  4. When you see the the first boot screen logo appear, press and hold the volume down key
  5. Continue holding throughout the boot process
  6. You’ll know you’re in safe mode because of the indicator on the bottom left of the screen
  7. Most third party apps won’t work in safe mode, so find a default app that does work to test the audio
  8. A good option would be to make a phone call and see if the microphone works
  9. If your microphone works in Safe Mode but not normally, an app you’ve installed is causing conflicts
  10. Try removing apps and clearing as much data as you can
  11. If this doesn’t work at first, you can try a more comprehensive solution and factory reset
  12. Continue reading for instructions on the factory reset process
  • Rule out corrupted firmware

By now the microphone should be working but if it isn’t working in Safe Mode either, you have all the reasons to suspect a corrupted firmware or some faulty settings. To resolve this issues it will require performing a factory reset, this will remove everything from the device and start it from new, including the microphone.

Before you factory reset your Samsung Galaxy S9 or S9 Plus you need to backup your data. To factory reset your device follow the steps below:

  1. Hold down the power button to turn off the phone
  2. Now press and hold the Volume Up, Power and Bixby buttons at the same time

  4. You should now release the buttons and start using the Volume and the Power keys to navigate through the list to choose an option
  5. Scroll down to the option that says ‘Wipe Data / Factory Reset’
  6. Then confirm with the ‘Yes’ option
  7. The factory reset will now start and may take some time. A yellow message will show at the bottom of the screen once done
  8. Finally, select the ‘reboot system now option’

Once your Samsung Galaxy S9 or Galaxy S9 Plus restarts you will have to set the phone up from scratch. When done, test your microphone with the recording app.

The problem should be solved, but in case it isn’t, you have only two options left:
