Troubleshooting Zoom audio issues on your mobile device

Issue

Audio does not work after joining a meeting in the Zoom mobile app on iOS or Android. Depending on the symptoms, you may experience one or more of the following:

• You cannot hear other participants in the meeting.
• Other participants cannot hear you in the meeting.

Environment

• Zoom mobile app for iOS (available on the Apple App Store)
• Zoom mobile app for Android (available on Google Play)

Note: If you are using the Zoom desktop app instead of the mobile app, see How to troubleshoot audio issues in Windows and macOS.

Cause

The issue may be caused by one or more of the following:

• In-app speaker is off: The Zoom in-app speaker is turned off.
• Device volume is muted: The device volume is muted or set to vibrate.
• Audio not connected: The device audio is not connected to the meeting.
• Microphone permission denied: Zoom does not have permission to access the device microphone.
• Microphone muted: You or the meeting host has muted your microphone.
• Microphone in use: Another application is using the device's microphone.

Resolution

If you cannot hear other participants

1. Turn on the Zoom speaker: If the speaker icon  in the top-left corner is turned off, tap it to turn it on.
2. Increase the volume on your mobile device: Use the device volume buttons or the notification panel. The device volume may be muted or set to vibrate even when the Zoom speaker is on.
3. Try earphones or a headset: Connect earphones or a headset with a built-in microphone and check whether you can hear the meeting.
4. Restart your mobile device.
5. Reinstall the Zoom mobile app from the Apple App Store or Google Play.

If other participants cannot hear you

1. Check whether you are muted.
   • If the Audio icon in the meeting controls shows that you are muted, tap it to unmute yourself.
   • If you remain muted, the host may have muted you when you entered the meeting. Ask the host to unmute you by sending a chat message.
2. Connect your device's audio to the meeting.
   • If the Join Audio icon appears in the meeting controls, tap it and select Call Over Internet.
   • If prompted, allow Zoom to access your microphone.
3. Try using earphones with a microphone.
4. Grant Zoom microphone access on your device as follows:
   • iOS:
     • Go to Settings.
     • Tap Privacy.
     • Tap Microphone.
     • Turn on the toggle for Zoom.
   • Android:
     • Go to Settings.
     • Tap Apps & notifications.
     • Tap App permissions or Permission Manager.
     • Turn on the Microphone for Zoom.
       Note: Android settings vary between manufacturers and service providers, so the exact steps may differ by device.
5. Close other applications that may be using the microphone.
   • iOS: Double-tap Home to view running apps, then swipe up to close an app.
   • Android: Tap the multitask button (usually the square icon in the bottom-right corner) to view running apps, then swipe left or right to close an app.
6. Restart your mobile device.
7. Reinstall the Zoom mobile app from the Apple App Store or Google Play.
