WhatsApp Call Not Working? Here's How to Fix It

WhatsApp is one of the most widely used messaging apps in the world, making it easy to stay connected through voice calls and video calls without paying traditional calling charges. Whether you’re speaking with family, attending an online interview, or joining a work meeting, WhatsApp calling has become part of everyday communication.

However, things become frustrating when a call refuses to connect, the screen stays on Connecting, the microphone stops working, or the other person cannot hear your voice. In some cases, video calls show a black screen, while in others the app displays a Call Failed message.

The good news is that most of these issues can be fixed within a few minutes. In many cases, the problem is related to internet connectivity, app permissions, Android settings, or an outdated version of WhatsApp rather than a serious hardware fault.

This guide explains the most effective solutions for WhatsApp Call Not Working on Android. It also covers common problems such as WhatsApp Video Call Not Working, WhatsApp Audio Call Not Working, WhatsApp Call Failed, WhatsApp Call Connecting Problem, microphone issues, camera problems, and poor call quality.

Before You Start

Before changing any settings, spend a minute checking these basics.

Your internet connection is stable.

WhatsApp is updated to the latest version.

Your Android phone has enough battery.

Camera permission is enabled.

Microphone permission is enabled.

Battery Saver mode is turned off.

VPN is disabled temporarily.

Your phone has been restarted recently.

Completing this checklist saves time and helps eliminate the most common causes of calling issues.

Identify Your WhatsApp Calling Problem First

Before you start changing settings, take a moment to identify the exact problem you’re experiencing. This can save time and help you jump directly to the most relevant solution.

Calls won’t connect: Check your internet connection, network settings, and WhatsApp server status.
Video calls aren’t working: Review your camera permission, internet speed, and camera availability.
Audio calls have no sound: Verify microphone permission, call volume, and Bluetooth settings.
Calls disconnect after a few seconds: Look for unstable internet, Battery Optimization restrictions, or VPN interference.
The other person can’t hear or see you: Check your microphone and camera permissions, then restart WhatsApp.
Incoming calls don’t ring: Review notification settings, background activity, and Battery Optimization.

Once you’ve identified the symptom, follow the corresponding troubleshooting steps below instead of trying every solution at random.

Identifying the exact symptom makes it much easier to fix WhatsApp Call Not Working without trying unnecessary solutions.

Why Is WhatsApp Call Not Working?

There isn’t a single reason why WhatsApp calls stop working. The issue can occur because of network problems, Android settings, app permissions, or temporary software glitches.

Some of the most common causes include:

Weak or unstable internet connection
Mobile data restrictions
Wi-Fi connectivity issues
Camera or microphone permission denied
Battery optimization limiting background activity
Outdated WhatsApp version
Corrupted app cache
Android software bugs
VPN or Private DNS conflicts
Temporary WhatsApp server outages

Instead of trying random solutions, follow the fixes below in order. This approach helps identify the exact cause without changing unnecessary settings.

Understanding the root cause is the first step toward fixing WhatsApp Call Not Working successfully.

Fix 1: Check Your Internet Connection

A stable internet connection is essential for WhatsApp voice and video calls. While text messages can often be sent over a slow connection, calls require continuous data transfer. Even small interruptions may prevent a call from connecting or cause it to disconnect unexpectedly.

If You're Using Wi-Fi

Move closer to your Wi-Fi router.
Restart the router.
Disconnect and reconnect to the network.
Test another website or video to confirm your connection is working properly.

If You're Using Mobile Data

Ensure mobile data is turned on.
Verify that you still have an active data plan.
Move to an area with stronger signal coverage.
Toggle Airplane Mode on for about 20 seconds, then turn it off.

Pro Tip: If calls work on Wi-Fi but not on mobile data, the issue is usually related to your carrier or mobile network rather than WhatsApp.

Overall, these steps should help resolve most WhatsApp Call Not Working issues caused by internet connectivity.

If your internet connection appears normal but WhatsApp calls still fail, you can also check the official WhatsApp Help Center for additional troubleshooting recommendations.

If your internet connection seems stable but WhatsApp still cannot make or receive calls, read our detailed WhatsApp Internet Connection Problem Guide for additional troubleshooting steps.

Fix 2: Verify WhatsApp Permissions

WhatsApp requires permission to use your phone’s microphone and camera. If either permission is denied, voice or video calls may not function correctly.

To Check Permissions

Open Settings.
Tap Apps.
Select WhatsApp.
Tap Permissions.

Ensure these permissions are allowed:

Camera
Microphone
Phone (if available)
Nearby Devices (on supported Android versions)

After enabling the required permissions, restart WhatsApp and place a test call.

Important: If you recently denied a permission request, WhatsApp cannot access that feature until you manually allow it in your phone’s settings.

Proper app permissions can quickly fix many WhatsApp Video Call Not Working problems.

If you’re unsure how Android app permissions work, refer to the official Android Help: Change App Permissions guide.

If your phone has broader Android-related issues affecting apps, check our Android Fastboot Mode Fix Guide for additional troubleshooting tips.

Fix 3: Restart Your Android Phone

Restarting your device is one of the simplest and most effective troubleshooting methods.

A restart refreshes Android’s system processes, reconnects network services, clears temporary memory, and often resolves minor software glitches that interfere with WhatsApp.

To restart your phone:

Press and hold the Power button.
Tap Restart.
Wait for the device to boot completely.
Open WhatsApp and test a voice or video call.

Although this solution may seem basic, it frequently resolves temporary calling issues without requiring additional troubleshooting.

Restarting your device is often enough to solve a temporary WhatsApp Call Not Working issue.

If your phone is overheating or slowing down frequently, it can also affect WhatsApp call performance. Learn more in our Phone Overheating Causes and Fixes Guide.

Fix 4: Update WhatsApp to the Latest Version

Running an outdated version of WhatsApp can lead to compatibility problems, especially after Android receives a system update.

Developers regularly release updates that fix bugs, improve stability, and enhance voice and video call performance.

To Update WhatsApp

Open the Google Play Store.
Search for WhatsApp.
If an Update button appears, install the latest version.
Restart the app after the update is complete.

Keeping WhatsApp up to date also improves security and ensures access to the latest features.

Using the latest app version can prevent many WhatsApp Voice Call Not Working errors.

Always install the latest version directly from the official Google Play Store to receive bug fixes and security updates.

If updating the app doesn’t resolve the issue, follow our complete How to Fix WhatsApp Not Working guide for more advanced troubleshooting.

Fix 5: Check Whether WhatsApp Is Down

Sometimes the issue is not with your phone.

Although uncommon, WhatsApp servers may experience temporary outages that affect voice calls, video calls, messaging, or status updates.

Possible signs of a server issue include:

Calls fail for multiple contacts.
Messages are delayed.
Status updates do not load.
Friends report experiencing the same problem.

If the problem is caused by a temporary server outage, the only solution is to wait until the service is restored.

Server outages can temporarily cause WhatsApp Call Not Working for users worldwide.

If you suspect a server outage, visit the official WhatsApp Help Center to check for known service issues and support information.

Fix 6: Disable Battery Optimization

Many Android phones automatically restrict background activity to extend battery life. While this feature is useful, it can prevent WhatsApp from maintaining a stable voice or video call.

To Disable Battery Optimization

Open Settings.
Tap Apps.
Select WhatsApp.
Open Battery.
Choose Unrestricted or Don’t Optimize, depending on your device.

This allows WhatsApp to remain active in the background, improving call reliability.

Pro Tip: If incoming WhatsApp calls are delayed or never ring until you open the app, battery optimization is often the cause.

Battery optimization settings may silently trigger WhatsApp Call Not Working problems.

You can learn more about battery optimization settings in the official Android Help Center.

If your phone’s battery drains unusually fast after long WhatsApp calls, our Battery Fast Drain Problem Solution Guide can help improve overall performance.

Fix Video Calls, Audio Calls, Camera, Microphone, and Network Issues

If WhatsApp Call Not Working even after completing the basic troubleshooting steps, don’t worry. Many calling problems are caused by Android settings that are easy to overlook. This section covers the most common issues that affect voice calls, video calls, microphones, cameras, and network connectivity.

Work through each solution in order. Even if a setting appears correct, checking it carefully can save you hours of frustration.

Fix 7: Clear the WhatsApp Cache

Temporary cache files help WhatsApp load faster, but they can sometimes become corrupted after an app update or unexpected system error. When this happens, voice calls or video calls may not work correctly.

How to Clear the Cache

Open Settings.
Tap Apps.
Select WhatsApp.
Open Storage or Storage & Cache.
Tap Clear Cache.

Restart WhatsApp and test another call.

Important: Choose Clear Cache, not Clear Storage. Clearing storage removes your local app data. If you ever need to reinstall WhatsApp, make sure you have a recent chat backup first.

Clearing the cache is one of the easiest ways to fix WhatsApp Call Not Working without losing chats.

If clearing the cache doesn’t help and the app still behaves unexpectedly, read our How to Fix WhatsApp Not Opening guide for additional solutions.

Fix 8: Allow WhatsApp to Use Mobile Data

Some Android phones allow you to restrict internet access for individual apps. If WhatsApp cannot use mobile data in the background, calls may fail or disconnect unexpectedly.

Check Your Data Settings

Open Settings.
Tap Apps.
Select WhatsApp.
Open Mobile Data & Wi-Fi or Data Usage.
Make sure these options are enabled:
- Mobile Data
- Background Data
- Unrestricted Data Usage (if available)

After making changes, close WhatsApp completely and open it again.

Correct mobile data settings often resolve WhatsApp Audio Call Not Working issues.

If mobile data isn’t working properly on your phone, check our detailed Mobile Data Not Working Guide before trying WhatsApp again.

Fix 9: Solve WhatsApp Video Call Not Working

If voice calls work but video calls do not, the problem usually involves camera access, internet speed, or another app using the camera.

Check Camera Permission

Go to:

Settings → Apps → WhatsApp → Permissions

Confirm that Camera permission is allowed.

Test Your Camera

Open the default Camera app on your phone.

If the camera works normally, the problem is likely limited to WhatsApp.
If the camera does not open, the issue may be related to your phone rather than the app.

Improve Video Call Quality

Use a strong Wi-Fi connection whenever possible.
Avoid large downloads while on a video call.
Close apps that are using the camera in the background.

Pro Tip: Low internet speed often affects video calls before it affects voice calls.

A stable internet connection is essential to fix WhatsApp Video Call Not Working successfully.

Fix 10: Fix WhatsApp Audio Call Not Working

Sometimes a WhatsApp call connects successfully, but no one can hear anything.

This problem can happen because of:

Disabled microphone permission
Bluetooth audio routing
Muted microphone
Temporary Android software bugs
Hardware issues

Try These Solutions

Increase your call volume.
Turn Bluetooth off if you are not using wireless earbuds.
Restart WhatsApp.
Test your microphone with the Voice Recorder app.
Check microphone permission again.

If your microphone works in every other application except WhatsApp, updating or reinstalling the app may resolve the issue.

Most WhatsApp Voice Call Not Working issues can be solved by checking audio settings.

Fix 11: Fix No Sound During WhatsApp Calls

Audio problems are among the most common WhatsApp calling complaints.

If You Can't Hear the Other Person

Increase the media volume.
Enable Speaker mode.
Disconnect Bluetooth devices.
Restart the call.

If the Other Person Can't Hear You

Make sure your microphone isn’t muted.
Remove any phone case that blocks the microphone.
Test the microphone using another app.
Confirm that WhatsApp has microphone permission.

If both users experience audio issues, check the internet connection on both devices.

These troubleshooting steps should eliminate common WhatsApp Audio Call Not Working problems.

If audio problems continue while using wireless earbuds or speakers, see our Bluetooth Not Working on Android guide for additional fixes.

Fix 12: Resolve Camera and Microphone Access Problems

Modern Android versions include privacy controls that allow you to disable camera and microphone access for all apps.

If either control is turned off, WhatsApp cannot use those features even when permissions are granted.

Check Android Privacy Controls

Open the Quick Settings panel.
Ensure Camera Access is turned on.
Ensure Microphone Access is turned on.

Once enabled, reopen WhatsApp and place a test call.

Camera and microphone permissions play a major role in fixing WhatsApp Video Call Not Working.

If media files are missing or unavailable inside WhatsApp, our WhatsApp Media File Doesn’t Exist Guide explains how to recover access.

Fix 13: Turn Off VPN and Check Private DNS

A VPN or custom Private DNS service may interfere with WhatsApp’s connection to its servers.

Temporarily Disable Your VPN

Disconnect the VPN.
Close WhatsApp completely.
Open the app again and place a test call.

Check Private DNS

Open Settings.
Go to Network & Internet.
Tap Private DNS.
Choose Automatic or Off.

If calls start working after changing these settings, the VPN or DNS configuration was likely causing the issue.

Disabling VPN services can often resolve WhatsApp Call Not Working on Android.

Fix 14: Stop WhatsApp Calls From Disconnecting

If calls connect but disconnect after a few seconds, unstable network conditions are often responsible.

Try these steps:

Move to an area with stronger signal strength.
Restart your Wi-Fi router.
Switch between Wi-Fi and mobile data.
Turn Battery Saver mode off.
Close apps that are heavily using your internet connection.

Pro Tip: If video calls disconnect repeatedly but voice calls remain stable, your connection may not have enough bandwidth for video streaming.

A stable network helps prevent WhatsApp Call Not Working and unexpected call drops.

If your Wi-Fi connection keeps dropping during calls, our Wi-Fi Not Working Guide can help you identify and fix the problem.

Fix 15: Reset Network Settings

If none of the previous solutions work, resetting your network settings can resolve hidden configuration problems.

A network reset restores:

Wi-Fi settings
Mobile network settings
Bluetooth settings

Your photos, apps, contacts, and WhatsApp chats are not deleted.

After the reset:

Reconnect to Wi-Fi.
Turn mobile data back on if necessary.
Open WhatsApp and test another call.

Resetting network settings can fix persistent WhatsApp Call Not Working issues.

Advanced Troubleshooting, FAQs, Prevention Tips, and Final Conclusion

If you’ve reached this section, you’ve already tried the most common fixes for WhatsApp Call Not Working. In most cases, one of the previous solutions resolves the problem. However, if your voice or video calls still aren’t working properly, the following advanced troubleshooting methods can help identify and fix more complex issues.

Fix 16: Check for Android System Updates

Even when WhatsApp is fully updated, an outdated Android version can cause compatibility issues with newer app features.

How to Check for Updates

Open Settings.
Go to System or Software Update.
Tap Check for Updates.
Install any available update.
Restart your phone after installation.

System updates often include improvements for network connectivity, camera stability, microphone performance, and security.

Keeping Android updated helps reduce WhatsApp Call Not Working caused by software bugs.

Fix 17: Reinstall WhatsApp Safely

If the problem continues after trying every solution, reinstalling WhatsApp can replace corrupted app files.

Back Up Your Chats First

Before uninstalling WhatsApp, create a recent backup.

Open WhatsApp.
Go to Settings → Chats → Chat Backup.
Tap Back Up.
Wait until the backup finishes successfully.

Now:

Uninstall WhatsApp.
Restart your phone.
Install WhatsApp again from the Google Play Store.
Verify your phone number.
Restore your backup when prompted.

Important: Never uninstall WhatsApp before confirming that your backup has completed successfully.

Reinstalling the app is an effective solution for stubborn WhatsApp Call Not Working problems.

If reinstalling WhatsApp doesn’t solve the issue, follow our complete WhatsApp Backup Stuck Guide to restore your chats successfully before trying again.

Fix 18: Test WhatsApp on Another Network

Sometimes the problem is caused by your internet provider rather than your phone.

Try switching between:

Wi-Fi
Mobile Data
Another Wi-Fi network

If WhatsApp calls work on another connection, your original network may be blocking or limiting internet traffic.

Testing another network can quickly identify the cause of WhatsApp Call Not Working.

Fix 19: Check Whether the Issue Is Limited to One Contact

If only one person cannot receive your WhatsApp calls, the issue may be on their device.

Ask them to check:

Internet connection
Camera permission
Microphone permission
WhatsApp updates
Battery Optimization settings

Testing calls with another contact helps determine whether the issue is device-specific or account-specific.

If the problem affects only one person, WhatsApp Call Not Working is likely related to that specific contact rather than your device.

When Should You Contact WhatsApp Support?

If you’ve completed every troubleshooting step in this guide and WhatsApp calls still aren’t working, it may be time to contact WhatsApp Support.

Consider reaching out if:

WhatsApp crashes every time you start a voice or video call.

Your camera and microphone work in other apps but never in WhatsApp.
The issue started after changing your phone number or moving to a new device.
The problem continues even after updating Android and WhatsApp to the latest versions.

Before contacting support, make sure you’ve backed up your chats and note the steps you’ve already tried. This information can help speed up the troubleshooting process.

If every solution has failed, contacting support is the next step to resolve WhatsApp Call Not Working.

When Is the Problem on WhatsApp's Side?

Although uncommon, WhatsApp occasionally experiences temporary server outages.

You may notice:

Voice calls fail for multiple contacts.
Video calls won’t connect.
Messages remain pending.
Status updates fail to load.
Several users report similar problems.

In this situation, changing settings on your phone usually won’t help. The best option is to wait until WhatsApp restores its services.

Sometimes WhatsApp Call Not Working is caused by temporary server issues that can only be resolved by WhatsApp.

If messages are also failing to send or receive along with calling issues, check our WhatsApp Not Sending Messages Guide for additional troubleshooting steps.
