Fix: Samsung Note 20 / 20 Ultra Microphone Not Working

Solution 1: Clean the Microphones

We love taking out our phones to capture beautiful moments or other important tasks. But, we forget to regularly clean the device. Whenever you take out the phone, there’s a high chance of dust particles sticking on the phone, and it can also pass into the microphone hole, which we usually do not notice.

You should clean the microphone hole before placing a call. The microphone may also have some water, which may lower the volume the other person hears. Hence, cleaning the microphone is the first thing you should do. Once the cleaning process is done, allow the phone to air-dry and check if the problem is fixed.

Solution 2: Restart Your Phone

A minor software bug or system glitch can cause issues with the microphone. These can be easily removed by rebooting the device. When you reboot the phone, the phone gets refreshed as all the running processes are stopped, and only essential processes are loaded once the device boots up.

A simple restart is enough in most cases, but if it does not work, you need to force restart your Samsung Galaxy Note 20 or Galaxy Note 20 Ultra. To normally restart the phone, press and hold the power button until the power menu appears. Select the Restart option.

To force restart your Samsung phone, press and hold the volume down button and power button for a few seconds. Release the buttons when the Samsung logo appears. All the apps running on the device will be forcibly terminated, and the device will reboot.

Solution 3: Remove Connected Bluetooth Devices

We often forget to turn off Bluetooth on our phones. Chances are that your Samsung device is already connected to a Bluetooth device, and that’s why the other person on the call is not hearing any audio. You should turn off the Bluetooth and remove all connected devices (headset, earbuds, etc.) before placing a call or recording audio.

Solution 4: Reboot the Phone in Safe mode

Third-party apps are useful, but many often create different kinds of problems on the device. Most of the time, this is the reason why your phone freezes, crashes, or lags. If a third-party app has anything to do with the microphone, you should remove it.

If unsure if a third-party app is causing the microphone problem, you should reboot the phone in Safe mode. In short, this mode disables all downloaded apps and loads only the original software that came with your device. So, if the microphone starts working in the Safe mode, you need to remove third-party apps from your phone.

Here’s how to reboot your phone in Safe mode:

1. Press and hold the power button until the power menu appears.
2. Now, touch and hold the Power off icon on the screen until you see the Safe mode icon.
3. Click Safe mode to reboot your Samsung phone in Safe mode.

Solution 5: Clear Cache

Here’s how to wipe cache on your Samsung phone:

1. Turn off your Samsung phone.
2. Press and hold the volume and power button until you feel the vibration.
3. Release the button simultaneously and wait for the Recovery Menu to appear.
4. Use the volume buttons to navigate the wipe cache option and press the power button to select.
5. Press the power button to select Yes.
6. Go to the Reboot now option and press the power button to select it.

Solution 6: Firmware Update

There could be a software bug in your Galaxy Note 20 or Note 20 Ultra, which is not allowing the microphone to work properly. Smartphone companies keep releasing new software updates that, in addition to new features and improvements, include bug fixing. Updating your Samsung phone to the latest firmware version can fix the problem with the microphone.

Steps to update your Samsung Galaxy phone:

1. Open the Settings app.
2. Go to Software updates.
3. Tap on Download and install. Wait until the latest firmware is installed.
4. Reboot your phone.
