Are Samsung's "Floating Gestures" the Solution to Too Big Screens?

I hear many people say they have to strain to reach the status bar or the upper left back button.

Maybe samsung could implement a no touch swipe down gestures that'll just work without having to touch the top.

Maybe a thumb flick to the top left could trigger a press in the upper left corner.

Do you think this could be the solution to the usability issue with big screens?
