When you join a Zoom meeting on the Zoom mobile app for iOS or Android, you may have microphone or speaker problems. You should try these troubleshooting steps to resolve the issue.

The following prerequisites must be met in order to troubleshoot audio on iOS or Android

You can download Zoom for iOS and Android devices (available on Apple App Store and Google Play)

How to troubleshoot speaker issues

The following steps will help you troubleshoot if you are unable to hear other participants in a Zoom meeting.

  • Make sure that you have the speakers turned on. To turn on your speaker, you will need to tap the icon in the top left-hand corner of your screen if it is turned off:
  • Press the volume buttons on your phone or tap the notification panel to increase the sound volume. Even if your device’s volume is set to vibrate or mute even when your speaker is turned on, it may still be set to muffle or mute the speaker.
  • I suggest you use headphones.
  • Turn off your device and restart it.
  • Make sure Zoom is re-installed from the Google Play Store or Apple App Store.

Problems with the microphone: Troubleshooting

Using the Zoom mobile app, click here to follow these steps in order to troubleshoot any issues you may be experiencing with your microphone:

  • If you are using a microphone, please ensure that it isn’t muted. It is possible to unmute yourself in the meeting control panel by tapping the muted Audio icon:

    The host might have muted you when you entered the meeting, if you are still muted. You can ask the host to unmute you by sending him a chat message.

  • Make sure that the audio is connected to your mobile device. There is an icon that says Join Audio in the meeting controls. It can be clicked on and you will be able to choose Call Over Internet. In the event that you are prompted to allow Zoom access to your microphone, please do so.
  • You may also want to try using headphones with a microphone.


  • In order to do this, you will have to make sure Zoom is allowed access to your device’s microphone.
    • iOS: Using an iOS device, go to Settings > Privacy > Microphone and toggle the Zoom option on.
    • Android: Go to Settings > Apps & notifications > App permissions or Permission Manager > Microphone and switch on the toggle for Zoom.
  • Please make sure there are not other applications that are using the microphone at the same time.
    • iOS: To find out which apps are currently running on your iOS device, double-tap the “Home” button. When an app needs to be closed, swipe up.
    • AndroidThe multitask button on Android devices (typically located in the bottom-right corner of the screen) allows you to view apps that are currently running. You can close an app by swiping left or right.
  • Make sure your device is restarted after closing an app.
  • You can reinstall Zoom from the Apple App Store or the Google Play Store.
