Oh! I quite like that change. I guess it’s similar to apple in that it’s separatated notofocations from quick settings, but doesn’t apple have a swipe up and swipe down? Or is it double pressing the home button? I haven’t held an iPhone in many years now, so i can’t remember. But how you access the two menus is different. I dont think an apple user who tried android for the first time would intuitively know how to access the two menus. So i wouldn’t say samsung had copied apple. Rather, they have been influenced by the idea. Plus, i believe stock android has this as an option in versions 15 and 16

That aside. You can go into your settings and swap back to the old notification shade.
