I gotta say this is my first UI beta and so happy to be a part of it. Everything so far look amazing. The new modern font looks great. The quick action swipe down from the right corner which gives you all icons looks good.
When I opened my phone it gave me an option to use gestures with swiping left, right, up, down, and getting rid of the buttons on the bottom of my screen. I don't like that at all. The love of having a Samsung is having a back and home button. This is one of the reasons why I can't stand iPhones. There is no home or back button. Let's hope they don't get rid of the home button in the future.
