20 Ways to Fix App Microphone Not Working
1. Check Microphone Permission
The first thing to check is whether the affected app has permission to use your microphone.
Android
Go to:
Settings → Apps → Select the App → Permissions → Microphone
Allow microphone access when the app is in use, if that option is available.
iPhone
Go to:
Settings → Privacy & Security → Microphone
Make sure the affected app is enabled.
After changing the permission, close and reopen the app.
2. Check System Microphone Access
Some devices have a separate system-level microphone privacy setting.
On supported Android devices, check:
Settings → Privacy → Microphone Access
Make sure microphone access is enabled.
On Windows, go to:
Settings → Privacy & security → Microphone
Make sure microphone access and access for apps are enabled.
If system-level microphone access is disabled, individual apps may not be able to use the microphone.
3. Restart the App
A temporary app glitch can prevent microphone access.
Try this:
- Close the affected app.
- Remove it from your recent apps if necessary.
- Wait a few seconds.
- Open it again.
- Test the microphone.
This is especially useful if the microphone stopped working suddenly.
4. Restart Your Device
If restarting the app doesn’t help, restart the phone, tablet, or computer.
A restart can clear temporary software problems and release microphone access that may have become stuck.
After restarting, open only the affected app and test the microphone again.
5. Test the Microphone in Another App
Determine whether the problem affects only one app or the entire device.
Try recording audio with:
- Voice Recorder
- Camera
- Another calling app
- Video recording
- Voice assistant
If the microphone works elsewhere, the problem is probably related to the original app.
If it does not work anywhere, investigate system settings or possible hardware problems.
6. Check Whether the App Is Muted
Some apps have their own microphone controls.
For example, during an online meeting or voice call, look for:
- Microphone icon
- Mute button
- Audio settings
- Input settings
Make sure the microphone is not muted.
If another person cannot hear you during a call, check the in-app microphone control before changing system settings.
7. Check the Correct Microphone Input
On computers, an app may be using the wrong microphone.
Open the app’s audio settings and look for Microphone, Input, or Audio Input.
Select the microphone you actually want to use.
For example, your computer may have:
- Built-in microphone
- USB microphone
- Webcam microphone
- Bluetooth headset microphone
- Wired headset microphone
Selecting the wrong input can make it appear that the microphone is not working.
8. Disconnect Bluetooth Devices
If Bluetooth headphones or earbuds are connected, your app may automatically use their microphone instead of the phone or computer’s built-in microphone.
Temporarily turn off Bluetooth or disconnect the Bluetooth device.
Then reopen the app and test the microphone.
If the microphone works afterward, the Bluetooth device or its audio profile may be causing the problem.
9. Check the Microphone Opening
A blocked microphone can produce extremely quiet or muffled audio.
Check the small microphone openings on your phone, tablet, laptop, headset, or webcam.
Dust, lint, or debris may block the opening.
Clean the outside carefully using a safe, dry method recommended for your device.
Do not insert sharp objects deep into microphone openings.
10. Update the App
An outdated app can contain bugs that affect microphone functionality.
Open your device’s official app store and check for updates.
Install the latest available version and restart the app.
If the microphone problem started after a recent app update, check whether a newer update is available.
11. Clear the App Cache on Android
If the affected app is on Android, corrupted temporary data can sometimes cause problems.
Go to:
Settings → Apps → Select the App → Storage → Clear Cache
Then reopen the app.
Clearing the cache generally removes temporary files rather than your account itself.
Avoid clearing app data unless necessary because it may remove locally stored settings or require you to sign in again.
12. Check Browser Microphone Permissions
If the microphone does not work on a website, the browser may be blocking microphone access.
Look for the site’s permission settings in your browser.
Make sure the website is allowed to use the microphone.
You may also check your browser’s privacy and site-permission settings.
After changing the permission, refresh the webpage and test the microphone again.
13. Check Windows Microphone Settings
If the app microphone problem occurs on Windows, check the system’s input settings.
Go to:
Settings → System → Sound → Input
Make sure the correct microphone is selected.
Speak into the microphone and watch the input level.
If the level does not move, Windows may not be receiving audio from that microphone.
Also check:
Settings → Privacy & security → Microphone
Make sure microphone access is enabled.
14. Check Microphone Volume
A microphone can technically be working while its input level is extremely low.
On Windows, open the microphone input settings and check the input volume.
If available, increase the microphone input level and test again.
Also check the app’s own microphone volume settings.
Avoid setting the level excessively high if it causes distortion or clipping.
15. Close Other Apps Using the Microphone
Another application may already be using the microphone.
Close unnecessary apps that may access audio, including:
- Video calling apps
- Recording software
- Voice assistants
- Streaming software
- Browser tabs
- Communication apps
Then reopen the affected app.
This can help if the microphone becomes unavailable after switching between several apps.
16. Turn Off Battery Saver Temporarily
Battery-saving features can restrict background activity or certain app functions.
If the microphone works inconsistently, temporarily disable:
- Battery Saver
- Power Saving Mode
- Extreme Battery Saver
- Low Power Mode
Then test the app again.
If the microphone starts working normally, check whether the app has battery optimization restrictions.
17. Update Your Device Software
An operating system bug can affect microphone access.
Check for available official system updates for your:
- Android phone
- iPhone
- Windows PC
- Mac
- Tablet
Install available updates and restart the device.
Keeping the operating system updated can also improve compatibility with newer apps.
18. Reinstall the App
If the microphone works in other apps but refuses to work in one particular app, reinstalling that app may fix corrupted files or configuration problems.
Before uninstalling, make sure important information is synchronized or backed up.
Then:
- Uninstall the affected app.
- Restart your device.
- Install the app again from the official store or website.
- Sign in if necessary.
- Allow microphone permission when requested.
- Test the microphone.
19. Reset App Permissions or Privacy Settings
If permissions have become misconfigured, resetting them may help.
Depending on your device, you may be able to reset app permissions or privacy settings.
Afterward, open the affected app and allow microphone access when prompted.
Be aware that resetting permissions can affect other apps too, so you may need to grant permissions again.
20. Check for a Microphone Hardware Problem
If the microphone does not work in any app, the problem may be hardware-related.
Hardware problems can occur after:
- A drop
- Water exposure
- Physical damage
- Dust or debris
- Internal component failure
- An unsuccessful repair
Test the microphone using another recording or calling app.
If there is no microphone input anywhere, consider having the device inspected by a qualified technician.
When Should You Get Professional Help?
Professional assistance may be appropriate if:
- The microphone does not work in any app.
- Audio recordings contain no sound.
- The microphone stopped working after a drop.
- The device was exposed to water.
- The microphone opening or internal component is damaged.
- A headset works but the built-in microphone does not.
- The problem continues after resetting permissions and reinstalling apps.
- Windows or another operating system cannot detect the microphone.
If the device has liquid damage, unusual heat, a swollen battery, or other serious physical damage, stop using it and seek qualified repair assistance.
Safety Tips
Follow these precautions while troubleshooting:
- Do not insert sharp objects into microphone openings.
- Do not pour cleaning liquid directly into the microphone.
- Do not open the device unless you have proper repair experience.
- Do not install random microphone driver or repair software.
- Use official app stores and trusted software sources.
- Back up important data before resetting or reinstalling apps.
- Keep water-damaged devices powered off and seek professional help.
