WhatsApp is rolling out a new update to its beta channel for Android users which takes the app to version 2.18.363.
The update adds an icon which makes it easier to initiate a group call in the app.
Currently to make a group call on WhatsApp for Android users have to call one person in the group and add the other members.
With the new icon, a user can easily call all the members in a group chat, either by voice or video.
The feature is currently non-functional but will be activated remotely at some point. The same feature has also been added to the iOS beta earlier. Sometime after testing commences the feature should roll out to the general public.
In the meantime, you can join the WhatsApp beta program via the Google Play Store here.
