Before you start…Before troubleshooting any microphone issues, make sure that the device isn’t paired with a Bluetooth headset or any wireless headphones. If it is, it could create issues during the troubleshooting process. Why? Because after a while, Bluetooth and wireless headsets are prone to fail and are likely to cause mic issues with your phone. Be sure to test the mic after you’ve removed your headset to make sure the headset itself isn’t the cause of your problems.
7 easy ways to troubleshoot Samsung Galaxy S7 microphone issues (and others)
Option 1: Have you tried turning it off and on again?Depending on what device you have, your first option is to remove the battery from the phone (Samsung Galaxy S7 owners, you obviously can’t do this. Just turn off your phone and grumble about Samsung’s decision to include a fixed battery). Remove the battery and let the phone sit for a minimum of 30 seconds. Place the battery back into the phone, power the device on, and test to see if the problem with the microphone has been fixed.
Option 2: Clean up the mic physicallyDespite the love we have for our smartphones, they are still considered to be one of the most regularly abused pieces of technology. Since your Galaxy probably ends up sharing the space in your pockets with plenty of items and nasty stuff like sand and grit, there’s a chance you could end up clogging the microphone hole even on a dust-proof device like the Samsung Galaxy S5 microphone. Rather than going commando to fix microphone issues on your Galaxy device, take a step back and try to visually identify the problem using a flashlight. On devices like the Samsung Galaxy S7 and older devices, you can find the microphone placed right around the charging port, which could be causing the sound issues every time you make a call. Start off by taking a thin and blunt plastic needle, or the pointy end of a toothpick if you aren’t feeling too brave and start scraping the inside of the microphone port carefully. Make sure you emphasize on being extra gentle with the pointy end because you could very well damage the mic if you poke it too hard. Once you’ve scraped out some of the dust and nitty gritty collected into the microphone port over time, use a vacuum to suck it all out or gently blow it out. With the mic hardware physically cleaned out, it could as well be the way to fix Samsung Galaxy S5 microphone not working issue that you’ve been looking for.
Option 3: Kick those third party apps to the curbSamsung Galaxy microphone problems could be caused by third party applications. In order to rule this out, start your device in safe mode and test the microphone while in safe mode. This nifty trick forces all third party applications to shut down so that only the built-in apps on your phone are functioning. Putting your device into safe-mode is a snap. Here’s how to disable any third party apps:
- Shut down 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.
- Your phone is now in safe mode; release the volume button and test the microphone.
Option 4: Noise reduction could be the hidden culpritMost audiophiles would appreciate the fact that modern devices like the Galaxy S7 and S7 Edge come with not just one, but two different microphones. While the one at the bottom is reserved for communications, the one on the top of the bezel helps in noise reduction and improving the quality of phone calls. However, this very useful feature could be working against you and might be causing the issue of Samsung Galaxy S7 microphone not working. If you are experiencing a significant drop in phone call quality, it wouldn’t harm to turn off Noise Reduction from the settings on your Galaxy device and see if it makes a difference.
- 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.
Option 5: Disabling other microphone enabled devices to reduce interferenceWhether you’re habitual to using your Android device with earphones, or often use it with a hands-free to have your conversations, there’s a good chance of experiencing microphone not working. Since not only earphones but Bluetooth-enabled headphones also come with a built in microphone inside them, the hardware and software of the devices could be conflicting when using them together.
- 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.
Option 6: Holding your phone the right way (especially for lefties)It almost seems absurd, but you’d be surprised by how some of the most excruciating problems with smartphones can be fixed so easily. Since the position of the microphone on devices like the Samsung S5 is on the bottom lip, there’s a decent chance that you could be blocking the mic port with your finger. This insanely easy way to fix Galaxy S7 microphone not working issue, which applies to most Galaxy phones as well, has been common among left-handed people. Take a step back and try to hold your phone as you usually do during phone calls and see if you’re inadvertently blocking the pathway for sound waves to reach the tiny microphone hole.
Option 7: “Last resort” factory resetLook, no one wants to do a factory reset. Even with cloud backups, you always end up losing some data, plus all of your settings get mangled. We know it blows, but sometimes only a factory reset can fix the issue. Sad face. On most phones, you can perform a factory reset by going to Settings and selecting “Reset to Factory Settings” or “Factory Reset”.
Done with troubleshooting? Test away!So at this point, you’ve taken the battery out and restarted your phone, checked those pesky third party apps, and/or do a factory reset. Now let’s see if your microphone is back up and running… Does the microphone work now? No? If you’re still having problems with your microphone, you could try cussing and swearing, but alas, your phone won’t hear you (nor will it care). This might be a good time to pop on over to your Samsung dealer with fingers crossed that it can be repaired. On the upside, it’s also a great time to sing it loud and proud, because only the neighborhood dog will know how off-key you’ve veered.
