WhatsApp is finally launching video calling for all of its one billion users (the service will be fully encrypted). It’s pretty simple – one just clicks the call icon to make a voice call then selects “video call” to activate it. A major plus point of WhatsApp’s (FB) video calling is cross-platform support, unlike FaceTime, which only works with Apple (NASDAQ:AAPL) devices, and Google Duo (GOOG, GOOGL), which isn’t compatible with older versions of iOS.
