Samsung Galaxy S9 and S9 Plus

The Samsung Galaxy S9 or S9 Plus are both affected by an extremely annoying problem with the Microphone, that prevents the most basic function of making and receiving calls. If the microphone on your Samsung Device isn’t working properly the person on the other end will not be able to hear you. Not to worry though we have an immediate fix for the issue.
For both the Samsung Galaxy S9 and S9 Plus, you can suspect the microphone issue is either a hardware or software problem. However, most hardware problems will need to be handled by a professional and require a special service that the regular user should not perform.
There are a couple of things we can test on the software. We can see if its a software or firmware problem, like a glitch or third-party app or even an issue with the device by following a few of the below solutions:

  • Rule out any accessories

You may find that an accessory such as a Bluetooth headset or headphones can easily affect your microphone. We can see if this is causing a problem by disconnecting your Samsung Galaxy S9 or Galaxy S9 Plus from any device. Once this is done test the microphone again, if you are still having problems, proceed with the following steps.

  • Give it a break

The same as with other phones you may find that turning off your Samsung Galaxy S9 and S9 Plus can fix the issue. You can also remove the SIM card and let it sit for a minimum of 30 seconds. Once you have done this put the SIM card back in the phone and restart the device. Check if the problem is still there, if it is follow the next step.

  • 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
  2. Wait thirty second and then turn the device back on
  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
  3. When you see the blue Android screen you will be redirected to the Recovery Menu
  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:

  1. Have a look at where the microphone is on your device, it may be clogged with dirt. If you think there is dirt, gently clean it and see if anything comes out or check for an improvement in quality.
  2. Finally, take it to the retailer or any authorized technician to fix your phone.

The above steps should resolve any hardware issues affecting your microphone on your device. If you have done all the software solutions above, you should not troubleshoot a hardware malfunction by yourself and so go to an authorized service to fix it.
There is another final solution for your Samsung Galaxy S9 or S9 Plus microphone problem. You can use an external microphone which can be found at multiple retailers. If you hate the thought of a wire getting in the way you can use a wireless external microphone.
