Ahead of troubleshooting, make sure you have the Zoom mobile app on iOS or Android (available on Apple App Store and Google Play).

Troubleshooting Speaker Issues

If you cannot hear other participants in a Zoom meeting, follow these steps to troubleshoot the issue.

  • Ensure your speaker is turned on. If you see the speaker icon in the top-left corner is turned off, tap it to turn on your speaker:
  • Increase the volume on your mobile device using the volume buttons or notification panel. Even if the speaker is turned on in Zoom, your device's volume might be set to mute or vibrate only.
  • Try using earphones.
  • Restart your mobile device.
  • Reinstall Zoom from the Apple App Store or Google Play

Troubleshooting Microphone Issues

If you are experiencing issues using your microphone with the Zoom mobile app, follow these steps to troubleshoot the issue:

  • Ensure the microphone is not on mute. If you see the muted Audio icon in the meeting controls, tap it to unmute yourself:
  • Ensure you have connected your mobile device's audio. If you see the following Audio icon in the meeting controls, tap it and select Call via Device Audio. If prompted, allow Zoom to access your microphone.
