In this complete guide, you’ll learn simple, step-by-step methods to fix microphone issues on Android phones. This guide is written in simple English so anyone can follow it easily.
Common Signs of Microphone Problems
Before fixing, confirm the issue. You may notice:

This is the easiest and most effective first step.
Sometimes a temporary software bug can stop the microphone.
Steps:
1. Press and hold the power button
2. Tap Restart
After restarting, test your microphone again.
2. Check If Something Is Blocking the Microphone
Your phone has a small microphone hole (usually at the bottom).
Sometimes:

• Phone case
can block it.
Fix:

Do not use water.
3. Test Microphone Using Voice Recorder
You need to check if the mic works at all.
Steps:
1. Open Voice Recorder app
2. Record your voice
3. Play it back
👉 If there is no sound → mic issue

Many apps need microphone access.
If permission is off, the mic won’t work.
Steps:
1. Go to Settings
2. Tap Apps
3. Select app (WhatsApp, Recorder, etc.)
4. Tap Permissions
5. Allow Microphone
6. Turn Off Bluetooth
