Whats app is equal to combine with.chat, voice, videocall, groups.etc
Love whatsapp because of encrypted chat , voice , and videocall.just allow evrty whatsapp user to update from their current version to most recent version update.that way everyone can enjoy video call feature even to those who don, t know about how to update it manually. I think whatsapp should change look of an app.that's all.and every indian use this app very easily.thank you.
