One feature that Samsung didn't mention much, or show up on stage, is the new 3D AR Emoji 2.0 technology. Basically, it's the answer to Apple's Animoji.
This year Samsung made it far better than we saw in 2018, and if you get the Galaxy 10+ it has dual cameras on the front to take a better 3D image of your face. The result is a pretty great emoji that's very lifelike and far better than anything else we've seen yet on Android.
Here's how it works. Snap a selfie using the front-facing camera, and your Galaxy S10 instantly turns you into an AR emoji. Your head moves on the screen as yours does in real life. It smiles when you do, shows your emotions or facial expressions, and it's completely customizable.
After you snap an AR Emoji you can go into customization and add glasses, change up your hair, get new shoes, or anything else for that matter. These emojis are easy to access anywhere, can be sent in messages, and give you a whole new way to express yourself and communicate.
Have fun with it.
