For me it’s the “tap to change volume” on my Galaxy Buds Pro. Such a great feature that saves touches for other functions.
Unless I’m trying to eat while wearing them, especially crunchy stuff, which causes the volume to go haywire (and only on the right, volume up, side).
So I switch to a pair of USB-C Buds when it’s Doritos time.
Theme park feels so inconsistent, it doesnt always look the way in real as mock up, some elements are connected where if I change one’s color it changes the others, there is no save and overwrite (have to always create a new what ever and delete the old one), and the icon splash screen has a lot of wasted white space when using custom icons. Im sure there are more but that is what jumps out at me.
