Symptoms
- Video call app shows a muted or no-mic icon
- Same phone works fine for regular calls
- Other participants say they can't hear you
- Different video call apps have the same problem
Likely causes
- CommonMicrophone permission denied for the specific appApps require individual mic permission separate from the phone's core calling function.
- CommonApp accidentally muted within its own interfaceVideo call apps have their own in-call mute button distinct from phone system mute.
- PossibleAnother app currently using the microphoneSome phones block simultaneous mic access, so a background app could be interfering.
- PossibleOutdated app version with a bugApp-specific bugs affecting mic access are sometimes fixed in updates.
- Less commonSystem-level microphone restrictionParental controls or device management profiles can block mic access for certain apps.
What to do
- Check the in-app mute button and confirm the microphone icon isn't showing as muted.
- Go to Settings > Apps > [app name] > Permissions and confirm Microphone is allowed.
- Close other apps that might be actively using the microphone in the background.
- Update the video calling app to the latest version from the app store.
- Restart the phone to clear any stuck permission or resource conflict.
- Test the same call with a different video calling app to see if the issue is app-specific.
- Check for any device management or parental control profiles that might restrict mic access.
- If the mic still doesn't work in any video app after granting permissions, try uninstalling and reinstalling the app.
When to call a pro
If mic permission is granted correctly but the mic still fails in every video app, consider a factory reset or professional diagnostic.
