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.
Change icon shape with Goodlock
It breaks the fluid adaptive icon, and doesn’t change folder or app pair shortcuts shape
Adds a background to some random icons
Swipe home animations are like the widget animations… smooth-ish, but nowhere near the fluidity of stock
I think Android 10 had a change icon shape in developer settings (teardrop, square etc) and I’d like something similar to that solution
