WhatsApp Microphone Not Working During Video Calls

Time Needed : 13 minutes

Most of the time, this problem isn’t really that serious as long as the issue isn’t with the hardware. If you’re one of the users that’s bugged by this problem, here’s what you should do:

1. Reboot your device

   At this point, it is possible that the cause of the problem is a minor glitch in the system, or the firmware itself just needs to be refreshed. 
   
   Thus, the first thing that you have to do is the reboot. It will refresh the memory as well as reload all services. 
   
   If the microphone still won’t work properly on WhatsApp during video calls after this, then move on to the next solution.
   

2. Check the permission

   The next thing for you to do if the problem continues after the restart is to check the permissions of the app. It is possible that the permissions were changed and that WhatsApp is no longer allowed to use the microphone. So follow these steps to make sure the permissions are correct: 
   
   1. Swipe up from the bottom of the screen to pull up the app drawer. 
   2. Go to the screen where WhatsApp is located. 
   3. Tap and hold on its icon until options show. 
   4. Tap App info. 
   5. Scroll down to find Permissions and tap on it. 
   6. The next screen will show you the services that the app is allowed to access. 
   7. Make necessary changes and then try using WhatsApp again. 
   
   After making sure WhatsApp can use the microphone and it still won’t work, then try the next solution.
   

3. Test the Microphone

   Before moving on, you should take a little time trying to find out if the problem is with the microphone alone. 
   
   Open the voice recorder and then try to record a few seconds of your voice. After that, play the recording and see if the microphone has captured your voice. 
   
   If it did, then the problem isn’t with the microphone. So, move on to the next solution to continue troubleshooting.
   

4. Clear cache and data

   After doing the basic microphone test, it’s time for you to troubleshoot the app itself. If it is just a minor app issue, then resetting WhatsApp will be enough to make things work perfectly again. This is how you reset it: 
   
   1. Go to the screen where WhatsApp  is located. 
   2. Tap and hold on the WhatsApp icon until options show. 
   3. Tap App info. 
   4. Touch Storage. 
   5. Tap Clear cache. 
   6. Now, tap Clear data and touch OK to confirm. 
   
   If this doesn’t work, then try the next solution.
   

5. Reinstall WhatsApp

   Instead of trying to find out if there’s an update, it’s better to simply remove the app from your phone to delete all possible corrupt cache and data files. After that, download a fresh copy from the Play Store to make sure you’re using the latest version. 
   
   1. Swipe up from the bottom of the screen to pull up the app drawer. 
   2. Go to the screen where WhatsApp is located. 
   3. Tap and hold on its icon until options show. 
   4. Tap Uninstall and confirm it. 
   5. Once the app is successfully uninstalled, launch the Play Store. 
   6. Search for 'whatsapp’ and tap the WhatsApp Messenger app. 
   7. Tap Install and wait until the phone has finished installing the app. 
   
   As long as the problem isn’t with the microphone or the hardware of your device, these procedures are enough to make WhatsApp work perfectly again.
