I think the most annoying bug is the gesture on the home screen. Unlike the gestures within an app or on homescreens of iPhones or pixel phones, the phone doesn't react directly with fading out the home screen. You have to perform the gesture, and then the cards pop in. Since Samsung is forced to implement Google's gestures, and it behaves different here, I consider this as a bug. Although it is still present in new phones like a51.
