I'm ambivalent to most of the UI changes in the Android 12 OS. The only thing I really don't like in the Android 12 UI changes is the quick toggle settings. There used to be 6 where there now are 4, yet it takes more space now.
And the internet toggle is a great example of terrible design: You swipe down, click the button on the top of the screen (with a misleading arrow on it that does nothing), then after a whole second on good hardware (SD695) a menu shows up at the bottom of the screen to disable WiFi and data, but the toggles randomly change position as WiFi networks are found. After to hit the toggle, you have to click out of the menu again. 2 extra clicks and all in totally different parts of the screen.
I have a suspicion this was designed in order to keep you connected to the internet all the time.
