Thanks to the useless “curved” screen since Galaxy S6 edge, you may very easily touch the screen inadvertently and therefore move or remove some app icons or widgets on the Home screen.

Although Galaxy S20 makes the curved part of the screen less obvious, it is still a big distraction and a big waste (of usable screen space).
