If after reading my guide on how to make video calls on WhatsApp you have encountered problems in the conversation and want to understand how to fix mobile phone microphone then I advise you to keep reading. I will help you to find out if the malfunctions are due to problems of software origin or are of a hardware nature.



If your friends complain about the quality of your voice and you don't hear audio in WhatsApp video calls, then it's time to run for cover. Let's see how.

WhatsApp video call does not hear audio on Android

If you have an Android smartphone (especially Samsung) and you have problems with the microphone during WhatsApp video calls, you can try to follow the solutions proposed below.

1. Remove the case

Try removing the phone case, screen protector, and anything else that might cover the speakers and microphone.

2. Test diagnostico hardware

Hardware diagnostic tests To fully verify that all hardware components are functioning correctly, dial the number * # 0 * # on the Samsung phone. Press on Receiver (this represents the microphone) If you hear a hum or hum, it means that the hardware side microphone is working 100%.

3. Cleaning the microphone

Check that the microphone hole is not blocked and try to physically clean it.

Turn off your phone and locate your smartphone's microphone hole. In Samsung phones it is usually placed next to the charging port.


To remove the dirt and then clean the microphone hole, take a thin plastic needle (a toothpick is fine too) and start to lightly and carefully scrape the inside of the microphone port being careful not to damage the microphone.


4. Microphone operation test

If during video calls on WhatsApp you experience audio problems with your Android smartphone, the advice is to do a test on the microphones. Follow these instructions for Samsung phones:

  • Log in to the phone application.
  • Enter the code * # 0283 # as you should make a call.
  • Select the item Start: RCV_1stMic / RCV Packet Loopback ON oppure Start: RCV_DualMic.
  • Hold the phone to your ear and say a few words [if you hear your own voice, the microphone at the bottom works]
  • Then select the item Start: SPK_2ndMic / SPK Packet Loopback ON.
  • Move the phone away and say something next to the second microphone, which is the one located at the top of the phone.
  • If you hear your voice [on speakerphone], the second microphone also works.
  • Press the button Exit.

If during the test you detected a voice at intervals or no response in output, I recommend that you go to a service center for the instrumental appraisal of the device. If you own a Samsung phone at this link you will find the list of Samsung service centers closest to you.


5. Check the permissions on the WhatsApp app

If you have passed the test but continue to have problems I recommend that you check the permissions granted to the app for access to the microphone by going to: Settings> Applications> App name> Permissions.

6. Restart your mobile phone

If any apps are causing microphone annoyance, your best bet is to try restarting your phone.

To restart a mobile Android, you have to press the power button for a few seconds, then select the item Switch off from the menu that appears in the center of the display and wait for the mobile device to switch off completely.


Then he presses the again power button for a few seconds, when turning on the device, check that the microphone is working correctly.
