1. The name: ufi(user friendly interface) instead of One ui
2. The sfinder: instead of placing the search bar at the top of the screen they can place it at the bottom in the app drawer. And also in the notification panel, they can place the Search button beside the "notification settings" at the bottom. So no need to reach the top or swipe notification twice
3. Icons: they look too cartoonish. Feels like an iPhone but for android users. And for me they don't look professional.
4. The gestures: instead of having three lines at the bottom, just one is sufficient. The actions can be tap for home, drag left or right to back and drag left or right for recents apps( depending on how you set yours) swipe up and hold for multitasking, and hold for Google assistant.
5. Allow us to use Samsung apps or Google apps and to disable those we don't use.
6. Bixby: just cancel it!
7. Boot animation: need a refresh, it's good but too hold.
8. Routine: implement the routine apps from goodlock in the system can be a game changer. Don't set it as a third party app but make it a part of the system. I'm sure everyone thinks the same about routine
9. Task manager: it's cool but too many steps to do multitasking. Just set it as in goodlock. It's much more easier and beautiful. And it gives more customization options.
10. Clock face: add them to the system. Not as third party app
11. Keyboard: space under the keyboard is useless and too much.
12. Edge panel: find a way to make it usable in landscape mode
13. Samsung pay: it's not totally compatible with the gestures. When I switch to gesture, if I want to use my Samsung pay app, there's a little lag of 1 second. The system switch back to normal nav bar, same thing when exiting the app. And I think you should remove the small pay card at the bottom of the home screen and just use the swipe up on fingerprint reader to open when the screen is on.
14. ARemoji: abandon the project!
Well it's true. Every second counts. Did you know that you can do a ton of small things within a second? Add a ton of ton of small things within a ton of seconds, and you got one big mess.
