WhatsApp officially launched the video calling feature for its over 1 billion users worldwide on iOS, Android and Windows phones.
To use the new feature, WhatsApp users can hit the call button in the top right corner of a conversation, which will bring up an overlaid interstitial asking if you want to voice or video call the friend or family member you’re chatting with. To kick off the video call, you simply select the “video call” option from this screen.
During the call itself, you can switch between the forward-facing and rear camera, mute the call or press the red button to hang up. It seems the user interface varies slightly on Android and iPhone in terms of where the picture-in-picture video feed is displayed, as well as the buttons’ size, lineup and placement.
If you don’t see the video call option on your device then go to play store and update the whatsApp application, then it will be available on your device.
