The first one i noticed was probably the Wearable app. It is a subtle, but good change. The i noticed the smart switch app. Then, today I was soooooo surprised. It was the music app. It looks beautiful. I don't have to hide It because it used to be so not fitting in. Now its looks AWESOME. I don't even remember how It used to look like. Ha! I have such a bad memory. I cant even remember an app icon.
One thing i could envelope on in another post, is that samsung should make the suggested words that you cant change back, not happen, and the suggested words on the top of the keyboard should be animated. You know what i mean. You should add animations everywhere. The transitions should be better. All transitions. Not only apps. Otherwise, I think samsung is miles ahead of every other tech company. Especially Apple. Thank you Samsung for Existing.
Another proof is this
