20 Ways to Fix Phone Microphone Not Working
1. Restart Your Phone
A temporary software glitch can prevent the microphone from working correctly.
Start with a simple restart:
- Turn off your phone.
- Wait a few seconds.
- Turn it back on.
- Test the microphone again.
Try making a call or recording a short voice message.
If the microphone starts working after restarting, the problem was likely temporary.
2. Check Whether the Microphone Is Muted
During a phone or video call, check the microphone button.
Make sure the microphone is not muted.
Some apps also have separate microphone controls for:
- Voice calls
- Video calls
- Voice recording
- Voice chat
- Live streaming
If the microphone icon shows that you are muted, tap it to enable the microphone.
3. Test the Microphone With a Voice Recorder
Use your phone’s built-in Voice Recorder or another trusted recording app.
Record a few seconds of your voice and play it back.
If the recording sounds normal:
The microphone hardware is probably working, and the problem may be limited to a particular app or calling feature.
If the recording has no sound:
The problem may involve the microphone, system settings, permissions, or hardware.
4. Check Microphone Permissions
Apps need permission to use your microphone.
Android
Go to:
Settings → Apps → Select the App → Permissions → Microphone
Allow microphone access when appropriate.
iPhone
Go to:
Settings → Privacy & Security → Microphone
Make sure the affected app is enabled.
After changing permissions, close and reopen the app.
5. Check System-Wide Microphone Access
Some phones provide a system-wide microphone privacy control.
On supported Android devices, check:
Settings → Privacy → Microphone Access
Make sure microphone access is enabled.
If system-level microphone access is turned off, individual apps may not be able to use the microphone even when their permissions appear correct.
6. Disconnect Bluetooth Devices
Your phone may be using the microphone on a connected Bluetooth headset, earbuds, or car system instead of the built-in microphone.
Temporarily turn Bluetooth off.
Then make a call or record a voice message.
If the microphone works normally after disconnecting Bluetooth, the connected accessory may be causing the problem.
Reconnect the device later and check its microphone settings.
7. Remove Wired Headphones or Accessories
If wired headphones, adapters, USB accessories, or other audio devices are connected, your phone may route audio through them.
Disconnect all external audio accessories.
Then restart the phone and test the built-in microphone again.
If the microphone works afterward, inspect the accessory or adapter for damage.
8. Clean the Microphone Opening Carefully
Dust, lint, and debris can partially block a phone’s microphone opening.
Locate the microphone openings on the phone and inspect them carefully.
Clean the exterior gently using a safe, dry method recommended for your device.
Avoid:
- Sharp pins
- Needles
- Excessive force
- Water
- Liquid cleaners
Do not push debris deeper into the microphone opening.
9. Remove the Phone Case Temporarily
A poorly designed or damaged phone case may partially cover a microphone opening.
Remove the case and test the microphone again.
If the microphone works without the case, check whether the case’s microphone opening is correctly aligned.
Consider replacing a damaged or poorly fitting case.
10. Check the Phone’s Speaker and Microphone Areas
Some phones have multiple microphones positioned around the device.
Inspect the phone for:
- Dust
- Lint
- Protective film
- Debris
- Physical damage
If a screen protector, case, or other accessory covers a microphone opening, remove or reposition it if appropriate.
Do not remove components from the phone itself.
11. Test Different Apps
Test the microphone in several applications.
For example:
- Voice Recorder
- Camera
- Phone calls
- Messaging apps
- Video calls
- Voice search
If the microphone works in one app but not another, the problem is likely related to the affected app’s permissions or settings.
If it fails everywhere, continue with system-level troubleshooting.
12. Update the Affected App
If the microphone problem happens only in one application, check for an app update.
Open the official app store and install any available update.
An outdated app may have compatibility problems with your phone’s current operating system.
After updating, restart the app and test the microphone.
13. Clear the App Cache on Android
If a specific Android app cannot access your microphone, clearing its temporary cache may help.
Go to:
Settings → Apps → Select the App → Storage → Clear Cache
Then reopen the application.
Avoid clearing app data unless necessary because it may remove saved settings or require you to sign in again.
14. Update Your Phone Software
A software bug can sometimes affect microphone access.
Check your phone for official system updates.
Android
Look under your phone’s Software Update or System Update settings.
iPhone
Go to:
Settings → General → Software Update
Install available official updates and restart the phone.
15. Turn Off Battery Saver Temporarily
Battery-saving features can restrict certain background functions.
If microphone access is inconsistent, temporarily disable:
- Battery Saver
- Power Saving Mode
- Extreme Battery Saver
- Low Power Mode
Then test the microphone again.
If the problem disappears, review the affected app’s battery restrictions.
16. Check for a Connected Car or Bluetooth System
If the microphone problem happens mainly during calls while driving, your phone may be routing audio through the vehicle’s Bluetooth system.
Disconnect from the car’s Bluetooth system and make a normal phone call.
If the microphone works normally afterward, check the car’s Bluetooth and hands-free settings.
17. Check for Water or Liquid Damage
If the microphone stopped working after your phone became wet, liquid damage may be involved.
Do not repeatedly test or charge a phone that has significant liquid exposure.
Instead:
- Disconnect charging accessories.
- Turn the device off if it is safe to do so.
- Avoid applying heat directly to the phone.
- Seek professional inspection if the problem continues.
Water damage can affect microphones and other internal components.
18. Reset Appropriate Settings
If the problem started after changing settings, a settings reset may help.
Depending on the phone, you may be able to reset:
- Network settings
- Privacy settings
- App permissions
- All settings
Review the warning carefully before confirming.
A network reset, for example, may remove saved Wi-Fi networks and Bluetooth connections.
19. Check for Physical Damage
Think about whether the microphone problem started after:
- A drop
- A strong impact
- Water exposure
- Screen repair
- Battery replacement
- Other phone repair
Internal components or microphone connections can potentially be damaged during an impact or repair.
If software troubleshooting does not help, professional inspection may be required.
20. Contact a Qualified Repair Professional
If your phone microphone still does not work in any app, the problem may be hardware-related.
A qualified technician can check the:
- Microphone module
- Internal connections
- Audio circuitry
- Charging-port assembly where applicable
- Motherboard
- Liquid-damage indicators
If your phone is under warranty, contact the manufacturer or an authorized service center before using an unauthorized repair service.
