How to fix Samsung Galaxy S7 microphone not working issue

When you want to test troubleshooting of your Samsung Galaxy microphone, make sure your device is not paired with a Bluetooth or wireless headset. This can cause troubleshooting problems. Why? This is because wireless and Bluetooth headphones are prone to interference over time and the phone’s microphone can cause problems. After removing the headset, test the microphone to make sure the headset itself is not the cause of the problem.

7 easy Steps to troubleshoot Samsung Galaxy S7 microphone issues and Possible others

STEP 1: Have you tried turning it off and on again?

Although, it Depends on the device, But the first option is to remove the battery from the phone (of course Samsung Galaxy S7 owners can’t do this. If you turn the phone off, Samsung decides to add a battery. Just complain (add) the battery. and press and hold the phone for at least 30 seconds Reinsert the battery into the phone, turn on the device and make sure the microphone is Restored

STEP 2: Clean up the mic physically

Although we have a soft spot for smartphones, they are still considered to be one of the most commonly abused technologies. Since your Galaxy may end up sharing the space in your pocket with many annoying objects and items such as sand and gravel, even on dust-proof devices such as the Samsung Galaxy S5 microphone, it may end up clogging the microphone hole. Don’t use commands to troubleshoot the microphone on your Galaxy device, but take a step back and try to visually identify the problem with a flashlight. On devices such as the Samsung Galaxy S7 and older devices, you may find that the microphone is located right around the charging port, which may cause sound problems every time you make a call.

If you feel that you are not brave enough, first take a thin and blunt plastic needle or the tip of a toothpick, and then start to carefully scratch the inside of the microphone port. It must be emphasized that the tip should be very gentle, because it may damage the microphone if it is struck hard. Once you have removed some dust and debris that has accumulated over time on the microphone port, use a vacuum cleaner to suck it up or gently blow it off. After physically cleaning the microphone hardware, it may also be a way to fix the Samsung Galaxy S5 microphone not working problem that you have been looking for.

STEP 3: Kick those third party apps to the curb

The Samsung Galaxy microphone problem may be caused by a third-party application. To rule out this situation, start the device in safe mode and test the microphone in safe mode. This wonderful trick forces all third-party applications to be closed so that only the applications built into the phone can run.

Putting your device into safe-mode is a snap. Here’s how to disable any third party apps:

  • Turn OFF the device and wait 30 seconds before turning it back on.

  • Press and hold the power button on your phone until a visual appears on the screen. This visual differs from device to device and generation to generation (but we promise you’ll know it when you see it). After it appears, release the power button.

  • Once you release the power button, press and hold the volume button down. Continue to do this until the device has fully rebooted.

  • At this point, the phone should be in safe mode—and the words, ‘Safe Mode’ should appear at the bottom of your screen.

  • Finally your phone is now in safe mode; release the volume button and test the microphone.

Another best  test is to use your device’s recorder to record a short audio clip. It’s best to mention this later in the manual. Play the clip again after recording is complete. If you can hear the sound clearly, it means the microphone is working normally outside the conversation. If you hear little or no sound, a reset may be necessary.

STEP 4: Noise reduction could be the hidden culprit

Most audiophiles will appreciate the fact that modern devices such as the Galaxy S7 and S7 Edge are not only equipped with one microphone, but also with two different microphones. The one at the bottom is used for communication, while the one at the top of the bezel helps reduce noise and improve call quality. However, this very useful feature may be detrimental to you and may cause the microphone on the Samsung Galaxy S7 to not work. If your call quality has dropped significantly, it’s okay to disable noise reduction from the Galaxy device’s settings and see if it’s different.

  • From the home screen of your Galaxy device, head over to the Phone app and navigate the keypad.

  • You should be able to see the “Menu” button on the top-right corner of the screen, so tap on it and select “Settings”.

  • Using the “Call Settings” menu, scroll down to find the “Additional Settings’ tab, where you should be able to find the Noise Reduction option.

  • The Noise Reduction feature is set to active by default, so simply press the checkbox next to it to disable it.

Please note that If the noise canceling and reduction feature of your Galaxy device was the culprit, disabling it from the Settings should help you counter it.


STEP 5: Disabling other microphone enabled devices to reduce interference

It do not matter if you frequently use an Android device with a headset or frequently use hands-free for calls, the microphone will most likely not work properly and that is why we are discussing on How to fix Samsung Galaxy S7 microphone not working issue. Since not only the headset but also the Bluetooth headset also has a built-in microphone, when they are used together, the hardware and software of the device may conflict.

  • If you aren’t connected to a Bluetooth device when taking calls, make sure that the Bluetooth is turned off on your Galaxy device.

  • Head over to Settings->Application manager and scroll down to find the Bluetooth tab. Open the Bluetooth app menu and tap on “Clear cache” to fix any unresolved pairing errors.

  • When you receive a call with earphones plugged into the headphone jack, the microphone may not work properly if the earphones are unplugged abruptly.

  • Similar to how you would check the microphone port on your smartphone, make sure that the small pinhole on your earphones and Bluetooth headphones is not covered in dust or grit.

STEP 6: Holding your phone the right way (especially for lefties)

This almost seems ridiculous, but you will be surprised that some of the most serious problems with smartphones can be solved so easily. Since the microphone on devices such as Samsung S5 is located at the bottom edge, you are likely to block the microphone port with your fingers. This extremely simple way to fix the Galaxy S7 microphone not working problem is also applicable to most Galaxy phones, and has long been common among left-handed people. Take a step back and try to hold the phone as you would normally do when making a call to see if you have inadvertently blocked the path of sound waves to the microphone hole.

STEP 7:  Factory Reset

As you can see, no one wants a factory reset. Even with cloud backup, you will lose data and obfuscate all settings. I know it will shut down, but a simple factory reset can fix the problem. sad face. Most phones can be reset to factory settings by going to Settings and selecting Factory Reset or Factory.

Therefore, at this time, you remove the battery and restart the phone, check for those annoying third-party applications, and/or perform a factory reset. Now let’s see if your microphone is working again…Is the microphone working now? Isn’t it? If you have been experiencing microphone problems, you can try to curse and curse, but unfortunately your phone cannot hear you (or care about it). This may be a good time to visit your Samsung dealer for repairs. On the bright side, this is also a good time to sing loudly and proudly, because only nearby dogs will know how you are out of tune.
