Top 11 Ways to Fix WhatsApp Video Call Not Working on iPhone and Android

WhatsApp started as an instant messaging app and included features such as voice calls, video calls, stickers, WhatsApp Web, end-to-end encryption, and more, over time. Among the latest reports, WhatsApp Payments (India) will debut in coming month or two. However, the rise of video calling frenzy has put the WhatsApp users in a tizzy. While many people try out new video calling options, several complain of WhatsApp video calls not working on iPhone or Android.


To meet the growing demand, the Facebook-owned company recently bumped member limit from four (4) to eight (8) for group video/voice calls. That would’ve easily led people make more WhatsApp video calls with their friends, family, and others. However, there are several reasons why video calls would fail randomly. For starters, WhatsApp app requires permissions to microphone and camera to make video calls work properly. And that’s one of the things to check out.

In this post, we have tried to cover every possibility that leads to WhatsApp video calls failure with solutions. Let’s check them out.

1. Update WhatsApp

WhatsApp frequently updates its app on iOS and Android. The video call problems might occur due to an old WhatsApp build on your phone. Navigate to App Store or the Google Play Store and update the WhatsApp app to the latest version. The WhatsApp Beta channel users on Android and iOS should update the respective WhatsApp builds to the latest versions, which carry several bug fixes and performance improvements.

2. Use Strong Network Connection

Video calls require a stable network connection to work smoothly. Also, they consume more data than WhatsApp voice calls. So, make sure that your phone is connected to a stronger network and your phone shows enough bars for cellular network strength. For those who own a dual-band router, you should check if your phone supports the 5GHz Wi-Fi band. And if it does, connect the phone to your Wi-Fi network’s 5GHz band.

3. Allow Necessary Permissions to WhatsApp

As noted earlier, WhatsApp requires microphone and camera permissions to make video calls successfully. You might have denied those permissions while setting up the app for the first time. That could be the reason why audio and video might not be working as expected. Check your phone’s Settings and allow the necessary permissions to the app.

For iPhone

Open the device Settings app, scroll down till you see WhatsApp, and open it. That’ll open ‘Allow WhatsApp to the Access’ window. Make sure the options for Microphone and Camera are enabled.

Alternatively, you can long-press on the WhatsApp app icon and select the info option from the context menu that rolls out. That will directly take you to the app info menu. There, select the Permission menu and enable permissions for Camera and Microphone.

Also, enable Data Roaming from the same window if you want to use WhatsApp video calls over cellular data while you’re on traveling in a different region.
