Fix WhatsApp video calling problems by switching internet connections, enabling camera and microphone access, and restarting or updating WhatsApp. Choose the check that matches your symptom, such as a failed connection, black camera preview, or missing incoming alert. Retry the call after each change to see whether it helps.
The short version
- Connection: Switch between Wi-Fi and mobile data, and ask the other person to check their connection too.
- Camera and sound: Enable WhatsApp’s camera and microphone permissions and check the call’s own controls.
- Missing calls: Review notifications, silent modes, and background restrictions when incoming calls do not ring.
- Last resort: Confirm your chat backup finishes before deleting WhatsApp or clearing its data.
| Fix | When to use it | Main caution |
|---|---|---|
| Change the connection | Calls fail, freeze, or disconnect | Mobile-data charges may apply |
| Restore camera and microphone access | Black preview or missing voice | Check system permissions and call controls |
| Restart and update | WhatsApp freezes or malfunctions | Restart controls vary by device |
| Check audio and accessories | Quiet, muted, or misdirected sound | Check whether sound also fails outside WhatsApp |
| Restore incoming alerts | Calls do not ring | Alert settings do not fix an active call’s picture |
| Check computer permissions | Desktop or browser calls fail | Browsers also need website permissions |
| Clear cache or reinstall | Persistent app malfunction | Back up before deleting app data |
| Reset the network or contact support | Earlier checks do not help | Network resets affect saved connections |
Try another internet connection
Switch from Wi-Fi to mobile data, or try another Wi-Fi network or hotspot, then place the call again. Move somewhere with stronger reception and ask the other participant to check their connection too. If the problem happens with only one person, have them update WhatsApp and repeat these checks before you reset anything on your phone. Mobile-data charges may apply.
Reconnect your phone by turning Airplane Mode on and back off, then turning Wi-Fi off and back on. Disconnect your VPN and retry. At a hotel, airport, or café, open the network’s sign-in notification and complete its login or terms page; switch connections if it still provides no internet access.
When only your home Wi-Fi fails, unplug the router for about 15 seconds, reconnect it, and wait for service to return. If calls fail only on a work or school network, ask its administrator whether WhatsApp calling is restricted. Being able to open WhatsApp does not establish that the network permits calling traffic.
On an iPhone that works over Wi-Fi but not mobile data, open Settings > Cellular > Show All and enable WhatsApp. If mobile data still fails, ask your carrier to check the connection and APN configuration.
Allow the camera and microphone
Check the camera and microphone icons during the call, and select either control to enable a disabled camera or unmute your microphone. Native app layouts vary, so check both controls even if you have already granted system permissions. Close another app using the camera, reopen WhatsApp, and retry.
On Pixel and other phones using Google’s Android menus, open Settings > Apps > See all apps > WhatsApp > Permissions. Open Camera and Microphone in turn, selecting Allow only while using the app for each. Other Android manufacturers may call the app list All apps.
On Android 12 and newer devices with global privacy switches, check those switches as well as WhatsApp’s permissions. Open Settings > Security & privacy > Privacy > Privacy controls, then turn on Camera access and Microphone access. Manufacturers can place these controls differently.
On iPhone, open Settings > Privacy & Security > Camera and enable WhatsApp. Repeat under Microphone. If camera access is already enabled, turn it off and on again, then reopen WhatsApp.
Restart WhatsApp and install updates
Close and reopen WhatsApp when it freezes or stops responding. On an iPhone with Face ID, swipe up from the bottom, pause, and swipe WhatsApp’s preview upward; on a model with a Home button, double-click Home and swipe the preview upward. Reopen the app and try another call.
Restart the phone if reopening WhatsApp does not help. On a Face ID iPhone, hold either Volume Up or Volume Down together with Side, drag the power-off slider, wait 30 seconds, then hold Side until the Apple logo appears. Other supported iPhones use Side or Top, depending on the model, to bring up the slider and turn the phone back on.
On Pixel 6 and later, hold Power + Volume Up for a few seconds and tap Restart. Other Android phones use manufacturer-specific controls, so use the restart procedure for your model.
Update WhatsApp through your app store next. On Android, open Google Play Store, tap your profile icon, select Manage apps & devices, and update WhatsApp under Updates available. On iPhone, open App Store, tap your profile photo or My Account, select App Updates, and tap Update beside WhatsApp.
Install an available phone software update if the problem persists. On iPhone, open Settings > General > Software Update; on Pixel, open Settings > System > Software updates. Follow the installation controls offered by your phone.
Check sound and connected accessories
For quiet or missing sound, press Volume Up during the call and check your headset’s mute control. Disconnect wired headphones or turn off Bluetooth in system settings to check the phone’s own speaker and microphone. If separate speakers and a microphone produce echo during a WhatsApp Web call, use a headset.
Remove a case or covering that obstructs your iPhone’s microphone openings, and clear debris from those openings. Record and play back audio in Voice Memos, then record videos in Camera with both cameras and listen to them. If sound also fails in those recordings, seek device service.
Check the camera outside WhatsApp when your preview remains black. If it also fails there, the problem extends beyond WhatsApp’s call settings. If your iPhone displays a temperature warning, turn it off, move it out of sunlight to a cooler environment, and wait before retrying.
Restore incoming call alerts
Check alert settings when outgoing calls work but incoming calls do not ring. In WhatsApp, open Settings > Privacy > Calls and turn off Silence unknown callers if you want calls from unknown numbers to ring. These settings control incoming alerts rather than picture or sound during an established call.
On Android, open Settings > Notifications > App notifications > WhatsApp and enable notifications. Review any available call notification categories and select an alerting behavior. Turn off Do Not Disturb in Quick Settings and retry an incoming call.
On iPhone, open Settings > Notifications > WhatsApp, then turn on Allow Notifications and make sure Sounds is turned on or set to a sound. Open Control Center, tap Focus, and tap the active Focus to turn it off. Retry an incoming call after making these changes.
Check background restrictions when calls arrive late or only after you open WhatsApp. On Pixel, open Settings > Network & internet > Data Saver > Unrestricted data and enable WhatsApp. If Extreme Battery Saver has paused the app, tap its paused icon and choose Unpause temporarily.
On Samsung Galaxy, open Settings > Battery > Background usage limits and check Sleeping apps and Deep sleeping apps. In the relevant list, tap More options > Remove, select WhatsApp, and tap Remove. Some Galaxy versions place Battery under Device care.
Check desktop and browser calling permissions
Computer calls need camera and microphone permission for the app or browser you use. In a WhatsApp Web session that offers calling, open an individual chat, click the video-camera icon, and allow camera and microphone access when prompted. You also need a working camera, microphone, audio output, and computer internet connection.
On Windows 11, open Settings > Privacy & security > Camera. Enable Camera access and Let apps access your camera, then enable WhatsApp if listed. For a browser or applicable desktop app, also enable Let desktop apps access your camera.
Return to Privacy & security and open Microphone. Enable Microphone access and Let apps access your microphone, then enable WhatsApp if listed. Enable Let desktop apps access your microphone for applicable desktop apps or browsers.
On Mac, open the Apple menu > System Settings > Privacy & Security > Camera and enable WhatsApp or your browser. Repeat under Microphone, then reopen the affected app if prompted. When using WhatsApp Web, grant access to the browser you use.
In Chrome, open Settings > Privacy and security > Site settings, then check both Camera and Microphone. Allow WhatsApp Web, select the intended camera and microphone, and reload the site. In Safari on Mac, open Safari > Settings > Websites and set WhatsApp Web to Allow under both Camera and Microphone.
For a Windows webcam, open its privacy shutter and enable its hardware camera switch if it has them. Reconnect a USB camera or try another port, then check it through Start > Camera. If the wrong microphone is selected, open Settings > System > Sound > Input and choose the intended device under Choose a device for speaking or recording.
Clear Android cache before reinstalling
On Pixel, open Settings > Apps > See all apps > WhatsApp > Storage & cache and tap Clear cache. Reopen WhatsApp and retry the call. Other Android phones may label the storage menu Storage.
Clear storage deletes app data and requires setting up WhatsApp again, so check your backup before using it or reinstalling. On Android, open WhatsApp’s More options > Settings > Chats > Chat backup > Back up. Wait for the backup to finish before deleting app data or uninstalling.
To uninstall on Android, open Google Play Store, tap your profile icon, and select Manage apps & devices > Manage > WhatsApp > Uninstall. Reinstall through the official WhatsApp download page and its app-store link.
On iPhone, confirm your chat backup first, then touch and hold WhatsApp and choose Remove App > Delete App > Delete. Reinstall from App Store and set up WhatsApp again. Choosing Remove from Home Screen alone does not uninstall the app.
Reset persistent connection problems or get help
Reserve a network reset for connection failures that persist after the simpler checks. On iPhone, open Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This affects saved Wi-Fi passwords and network, VPN, and APN settings, so prepare to rejoin Wi-Fi afterward.
On Pixel, open Settings > System > Reset options > Reset Bluetooth & Wi-Fi > Reset settings. Reconnect your Wi-Fi network and Bluetooth accessories afterward. Other Android manufacturers may use different reset labels.
If calls still fail, open WhatsApp’s Settings > Help > Help Center > Contact Us. Include your device, operating system, WhatsApp version, exact symptom, and whether another network or client works. If an error appears, take a screenshot of the error to keep its exact wording available when contacting support.
Frequently Asked Questions
Why do messages work through WhatsApp Proxy but video calls fail?
WhatsApp’s official proxy supports messaging and media, but it does not support voice or video calling. Use a direct internet connection that permits WhatsApp calls.
Why does switching a voice call to video not happen immediately?
In a one-to-one WhatsApp Web voice call, click the video-camera icon and select Switch. The other person must accept the change before the call switches to video. Do not assume every group voice call supports the same transition.
Can Use less data for calls fix poor video quality?
You can compare call behavior with Use less data for calls enabled and disabled, but neither position guarantees a fix. On Android, open WhatsApp’s More options > Settings > Storage and data > Use less data for calls.
Can Protect IP address in calls affect call quality?
Yes, WhatsApp says relaying calls through its servers can reduce quality. On Android, open WhatsApp’s More options > Settings > Privacy > Advanced > Protect IP address in calls to temporarily disable it and compare. Turning it off changes the privacy protection for eligible calls; group calls are already relayed.
What operating system does WhatsApp require?
As of October 8, 2026, you need Android 6.0 or newer or iOS 15.1 or newer. WhatsApp has announced that its iPhone minimum becomes iOS 15.5 on November 30, 2026. Update your operating system or move to a supported device if your phone falls below the requirement.
How do you remove an unwanted Samsung video call background?
On supported Galaxy phones, open Settings > Advanced features > Video call effects > More options > Delete background image, then tap the red minus control. During a compatible call, you can also open Quick settings with a two-finger swipe and tap Video call effects to inspect the active controls.
