If the microphone is not working on your Samsung Galaxy Z Flip 3, you’re not alone. Many users have reported the microphone (one at the bottom of the phone near the charging port) on Samsung Galaxy Z Flip 3 not picking up sound or functioning as it should. 

There are multiple reasons for this, and the most common ones are software glitches in the phone’s operating system and hardware defects or damages to the microphone unit.

In this guide, we will give you 4 troubleshooting techniques to help you identify and resolve the microphone not working issue. If it’s a software problem, you should be able to fix it yourself with the first four solutions. However, if it’s a hardware issue, we will guide you on what to do next.

Fix 01: Do a Forced Restart

The Samsung Galaxy Z Flip 3’s microphone not working issue could be due to minor software glitches. These glitches interfere with the normal functioning of your device, including the microphone. A simple solution to this problem is to perform a forced restart.

This is because a forced restart is similar to a battery pull procedure that refreshes your phone’s memory as well as reloads all its apps and services.

Here’s how to do a forced restart on your Samsung Galaxy Z Flip 3:

  1. Press and hold the power key and volume down key together until you get the power menu.
  1. Tap on the restart button.

  1. Confirm by tapping on the restarting button again.

After the restart, test the microphone to see if it’s now working. You can do this by making a call or recording a voice note.

Fix 02: Check the Case/Cover

If you are using a cover or case for your Samsung Galaxy Z Flip 3, and If that cover is blocking the microphone hole, your device won’t be able to pick up any sound. This is a common issue that many users overlook.

Here’s what you need to do:

  1. Remove the case or cover from your Galaxy Z Flip 3.
  2. Once you’ve removed the case, try making a phone call or recording a voice note.

If the microphone works without the case, then the case was the problem. In this case, consider getting a new case that doesn’t block the microphone hole.

Fix 03: Boot Your Galaxy Z Flip 3 to Safe Mode

If you’ve recently connected your Galaxy Z Flip 3 to a Bluetooth device, it’s possible that the Bluetooth process could be interfering with your device’s microphone functionality. Booting your device into safe mode can help you determine if this is the case.

Safe mode is a diagnostic mode of the Android operating system. In safe mode, an operating system has reduced functionality, but the task of isolating problems is easier because many non-core components are disabled.

Here are the steps to boot your Galaxy Z Flip 3 into safe mode:

  1. Press and hold the power button until the power off menu appears on the screen.
  2. Tap and hold the Power off option until the Safe mode option appears.
  3. Tap Safe mode. The device will restart and ‘Safe mode’ will appear in the lower-left corner of the home screen.

Once you’re in safe mode, try recording a voice note or making a call to see if the microphone is working. If it is, then a third-party app or the Bluetooth process is likely causing the issue. 

Once you identify the root cause, restart your device to exit safe mode and begin uninstalling any app you have previously installed that controls the microphone of your smartphone. Also, you can turn on and off Bluetooth to ensure it is not interfering with the operating system.

Fix 04: Take the Device to a Samsung Repair Center

If the microphone on your Samsung Galaxy Z Flip 3 is still not working even after trying all the above solutions, it’s likely that the issue is hardware-related. This means that the microphone component of your device is defective or damaged.
