The video calling feature would come to iOS first followed by Android, and would be supported both by WiFi and cellular connections. Muting the microphone would be another option available to users.
Version 220.127.116.11 of WhatsApp is expected to have video calling. Keeping in mind that version 2.12.12 is already available in the App Store, the next WhatsApp update for iOS users may support this feature.
Along with video calling, new WhatsApp updates are also expected to include a makeover centered around WhatsApp’s trademark green colour. There will also be support for multiple chat windows at one time, allowing the user to move back and forth. We’ll keep you updated as and when new changes develop.
