Last May when the F8 event, WhatsApp announced the group’s voice and video calling function. With this function, four users can chat simultaneously via the WhatsApp application. This function was finally activated this morning.
To use this function the user should only start a voice or video call. Once started they can add new members by pressing the “add participant” button on the top right corner of the screen.
Like their messaging service, all voice and video calls are encrypted to avoid being spied. This function can be used on Android and iOS devices.
