New Snapchat now separates the social from the media. This means that the Chats and Stories from your friends are on the left side of Snapchat, and the Stories from publishers, creators, and the community are on the right. It also includes algorithm changes to surface your best friends.
Bitmoji lets you have fun by creating a personal emoji. Start with the creation of your avatar and then use your Bitmoji on Snapchat to chat your friends.
