I don't see how I am off topic, my response still pertains to the problem. Here is a visual representation where hopefully you'll see the issue.

Pink: where CC would best be activated including swipe gestures
Green: where in the possible bezel iPhone CC would be activated if there are no changes including swipe gestures
Red: a rough position where the gesture would not be recognized, trying to start the swipe around this area is a hit and miss
Yellow: where in the bezel less iPhone would the swipe gesture need to expand in order to work properly along with other gestures at the expense of accidental activation.
