If one user presses the video button, the other user will be prompted to accept the video call. If the other user accepts, the voice call gets converted to a video call. Previously, users had to cut the call to switch from a voice call to a video call.The feature currently works on Android devices with Android 6.0 and above.WhatsApp in a previous beta version (2.17.443) introduced features like Facebook stickers, a new layout for the GIF button and option to manage groups by demoting or removing a member from the group. It also hinted at group voice and video calls on the app. An option to reply privately to a group member was also seen in one of the previous beta updates.
