Also getting a big update in iOS 10 is the Messages app. New features include inline rich links, which open YouTube videos, images and other types of media—videos now play right within the app!—a built-in Camera viewfinder, and some great emoji improvements.
These improvements include 3x bigger emoji images within your messages, so you can see the icons in greater detail, and predictive emoji. Apple calls this "emojifiable." So the Messages app in iOS 10 can essentially guess emoji images for the words you tap on.
