One of our favorite features on the Galaxy Note 8 was the ability to turn any video into a GIF with the S-Pen. Simply play a video, pull out the stylus and do some cropping and you're done. And while that's still an option, Samsung built on that idea with a new feature called Live Messages.
When you use the S-Pen to write on the screen anything you write is available to send as a Live Message. Basically a GIF. There's even a dedicated option in the S-Pen menu for Live Messages. As you write the letters sparkle and glisten on the screen. Then, you can send that message as an animated GIF that essentially plays the message on the other end for whoever receives it. It's hard to explain in words, but you'll find it once you open your Note 9. Try it today.
