What to do
- Check the specific app's permissions in settings to make sure microphone access is allowed.
- Remove the case and check that nothing is covering the microphone hole.
- Test the microphone in a different app (like a voice memo app) to see if the issue is app-specific.
- Clean the microphone hole gently with a soft dry brush or compressed air.
- Restart the tablet to rule out a stuck audio service.
- If no app can use the microphone even with permissions granted and the hole is clear, the hardware itself may need repair.
