• The video above does a wonderful job of explaining how the new interface works — as long as both you and your friend have data or Wi-Fi, you'll be able to talk through audio or video just like any other video conferencing interface. To open a chat, swipe from left to right, or hit the 'New Chat' icon in the upper-right corner and choose who you wish to call.
