WhatsApp's latest update for its iPhone app introduces the ability to send original quality media as a file, without compression or quality loss. This feature is now rolling out widely for all iPhone users who install the latest update from the App Store. In addition, iPhone users can now start voice chats in large groups without ringing everyone, and they will see new bubbles in chat to track missed, ongoing, and completed calls.
