How To Fix Galaxy S8 And Galaxy S8 Plus Microphone Problems

Posted by Robert Hayes on February 8, 2019

If you are having problems with the microphone on your Galaxy S8 or Galaxy S8 Plus, you know that this is one of the most annoying problems to have because it affects the most basic function of your phone: making and receiving phone calls. If your microphone isn’t working, then people can’t hear you talk, and this is obviously an issue that requires an immediate solution. In this article, I will show you how to diagnose and troubleshoot problems with the microphone on your Galaxy S8 or Galaxy S8 Plus smartphone.

As is usual with smartphone problems, there are two basic possibilities behind any particular issue. One, the problem is being caused by broken or defective hardware, and two, the problem is being caused by a software glitch. If the problem is being caused by hardware, then your recourse as an end user is limited. There are a couple of things that an end user can fix or attempt to fix themselves, but most hardware problems required a technician. If the problem is being caused by software, however, there are more options.

It is generally a good idea to rule out user-fixable hardware problems first, as they are usually simple to check.

Look at Your Accessories

If your phone has a Bluetooth headset or headphones, then there could be hardware conflicts between those add-on devices and your microphone. Disconnect your headphones and turn off Bluetooth on your Galaxy S8 or Galaxy S8 Plus and see if that clears up the problem.

Check for Dirt

It isn’t common, but is there dirt or grit in your microphone to the point of blocking it from functioning correctly? If so, a quick blast of compressed air from a can of compressed air sold for the purpose of cleaning out keyboard gunk will clear up the problem immediately.

Turn It Off and On Again

There’s a reason that tech support always tells you to reboot the computer. For many software problems, a reboot is sufficient to resolve whatever was wrong and get things working properly again. To ensure a complete reset of your phone, remove the SIM card and the battery, let the phone sit for 30 seconds or so, then reinsert the SIM and the battery and turn the phone back on.

Check for Third-Party Problems

If everything was working fine, and then you installed the GoopMasterBlaster app and suddenly your microphone stopped working, then there’s about a 99.9% chance that the new app is the source of the issue. You can either uninstall the app immediately, or test the theory that is responsible by booting your phone into Safe Mode (which blocks third-party apps from running) and seeing if the problem goes away. If it doesn’t go away in Safe Mode, then the problem isn’t the new app. If it does go away, then you can uninstall the app and resolve the issue.

To boot into Safe Mode:

  1. Turn off the phone
  2. Press and hold the Power button
  3. Release the button when “Samsung Galaxy S8” or “Samsung Galaxy S8 Plus” shows on the screen
  4. Press and hold the Volume Down button immediately after that until your phone finishes restarting
  5. You should see the words “Safe Mode” at the bottom of the display
  6. Release the Volume button

Clear Your Cache

The cache on your phone is a storage area devoted to the operating system or individual apps. Sometimes if the cache becomes damaged or corrupted, this can cause issues with the operation of the phone, including your microphone. This TechJunkie article on how to clear your cache gives you the necessary steps for this option.

Backup and Restore

The last resort is to backup your phone’s data and applications and then do a factory reset. This will resolve any possible software issue. It is important that you back up first, however, as a reset is going to erase all the data on your phone. This TechJunkie article on how to factory reset your Galaxy S8 or Galaxy S8 Plus will show you how to perform this task.

If despite all of these steps, your microphone is still not working, then the bad news is that there is probably something physically wrong with your microphone and your phone will need to be repaired by an authorized technician or replaced by the retailer or service provider you bought it from.

One final possible workaround: there are both wired external microphones and wireless external microphones available on the market, and if your built-in microphone won’t work but repair or replacement aren’t options, then one of these solutions may be the answer.
