Why is my WhatsApp microphone not working during calls
Jul 25, 2025 am 12:46 AMCheck WhatsApp microphone permissions in device settings, as denied access is the most common cause; enable it under Apps > WhatsApp > Permissions on Android or Privacy & Security > Microphone on iPhone. 2. Clean the microphone port using a soft brush or compressed air to remove dust or debris blocking the audio input. 3. Restart WhatsApp by closing it from the app switcher, and if needed, restart the phone to resolve temporary glitches. 4. Ensure both WhatsApp and the device operating system are up to date via the app store and system update settings. 5. On Android, clear WhatsApp cache through Settings > Apps > WhatsApp > Storage > Clear Cache to fix data-related issues without losing chats. 6. Test the microphone in other apps like voice recorder or FaceTime; if it fails everywhere, the issue may be system-wide or hardware-related. 7. As a last resort, back up chats, uninstall and reinstall WhatsApp from the official store to reset app settings. If the microphone fails across all apps even after a factory reset, physical damage from water, drops, or improper repairs may be the cause, requiring professional service. Most WhatsApp microphone problems are resolved by addressing permissions or cleaning, followed by software troubleshooting, and the issue typically isn't the app itself but rather device-level settings or hardware damage.
If your WhatsApp microphone isn't working during calls, it can be frustrating—especially when you're trying to have a conversation. The issue isn't always the same for everyone, but here are the most common causes and how to fix them.

1. Check App Permissions (Most Common Fix)
WhatsApp needs access to your phone’s microphone to work properly. If permissions are denied, the mic won’t function.
On Android:

- Go to Settings > Apps > WhatsApp > Permissions
- Make sure Microphone is turned on
On iPhone (iOS):
- Go to Settings > Privacy & Security > Microphone
- Ensure WhatsApp is toggled ON
? Tip: If you recently updated your phone’s OS, permissions may have reset. Re-granting access often fixes the problem instantly.

2. Clean the Microphone Port
Dust, lint, or pocket debris can block the microphone (usually a tiny hole at the bottom or back of your phone). Even partial blockage can make it seem like the mic isn’t working.
- Use a dry, soft brush or a can of compressed air
- Gently clean around the mic openings
- Avoid using sharp objects
? Try making a regular phone call or recording a voice memo to test if the mic works outside WhatsApp. If it fails there too, it's likely a hardware or system-level issue.
3. Restart WhatsApp or Your Phone
Sometimes, a simple restart resolves temporary glitches.
- Close WhatsApp completely from the app switcher
- Reopen it and test the mic on a call
- If that doesn’t help, restart your phone
This clears any stuck processes that might be interfering with audio hardware.
4. Check for App or System Updates
Outdated apps or OS versions can cause compatibility issues.
- Update WhatsApp via Google Play Store (Android) or App Store (iPhone)
- Check for system updates:
- Android: Settings > Software Update
- iPhone: Settings > General > Software Update
Older versions may have bugs affecting audio routing or permission handling.
5. Clear WhatsApp Cache (Android Only)
Too much cached data can interfere with app functions.
- Go to Settings > Apps > WhatsApp > Storage
- Tap Clear Cache (not “Clear Data” unless necessary)
This won’t delete your chats but may resolve performance issues.
6. Test with Another App
See if the microphone works in other apps:
- Voice recorder
- FaceTime or Google Meet
- Siri or Google Assistant
If the mic fails across all apps, the issue is likely system-wide—possibly hardware or OS-related.
7. Reinstall WhatsApp (Last Resort)
If nothing works:
- Back up your chats (Google Drive or iCloud)
- Uninstall WhatsApp
- Reinstall from the official app store
- Restore your backup
This resets app settings and permissions and often resolves deep-seated bugs.
When It Might Be Hardware
If the microphone doesn’t work in any app—even after a factory reset—there could be physical damage. This is more common after:
- Water exposure
- Drops
- Using third-party repair services
In such cases, visit an authorized service center.
Basically, start with permissions and cleaning, then move to software fixes. Most mic issues in WhatsApp aren’t the app’s fault—they’re permission or hardware-related. Fixing it step by step usually gets things working again.
