Since the top-edge-gesture is virtually impossible to use comfortably on big screen devices like the Jolla C, I suggest new alternative gestures which are sketched in the following image:
Basically they consist of short edge swipes followed by an upward / downward swipe. Since the edge swipes can be done at any height of the display, they would be perfectly suitable for big screens. I would suggest associating the left-to-right-upward swipe with closing the running app and the right-to-left-downward swipe with the screen lock. But ideally, the getures should be fully customizable by the user.
