• 1st You must have "One Handed Operation+".You can download it from Play store or Galaxy store.

• 2nd choose your handle. For me I've chosen right handle. As I hold it mostly on my right hand.

• 3rd choose diagonal up from short swipe. Set it to screen off. 

• Done

Now just diagonal upward swipe will instantly turn off your screen. No need to use button and you don't have to be in home screen to double tap turn it off. Like for more tips
