The photo button allows you to send pictures from your phone’s library, the phone button allows you to make voice calls, the snap button (as you might expect) allows you to send a snap, the video button starts a video call with your contact, and the sticker button gives you the chance to reply using one of several hundred stickers.
It should also be noted that right now you can only video chat with one friend at a time.
One of the new features that has been causing Snapchat users the most distress has been the new auto-advance feature while watching stories.
You’ll also notice that when you write a message on your snap you can now write more than a single line (up to two lines and a few characters) – finally!
As I mentioned above, the biggest part of this update were the changes made to the chat features on Snapchat.
