Gotta strongly disagree on this. For example, I know there's a way to get to the app switching screen, which shows all of the apps in a grid. You just have to drag up from the bottom the right amount in order to get the grid to stay. Despite knowing this, I fail to do it half the times I try. I just can't figure out how much to "drag" up from the bottom. Too much or too little and it just doesn't work. So frustrating. And so many other similar examples.
