WhatsApp launched encrypted group video calls
WhatsApp has supported video calling since 2016, but calls were, until now, limited to two participants. With the latest change, the app is upping its support to four total participants. That's a fairly modest increase, particularly compared to other services. Facebook Messenger supports group video calls of up to 50, while Skype supports 25 participants. But the feature is likely more challenging for WhatsApp than some of its competitors. Its video calls, like other messages sent within the app, are end-to-end encrypted by default, for one thing. The company also needs to ensure new features are optimized for people with slower connections and older devices.
WhatsApp alternatives are: Viber, Line, ICQ, BBM, Skype, Telegram, Google Hangouts, WeChat, Kik, Facebook Messenger
