In the Post #3 there's a ScreenShot ( 1° image One-Handed Operation)
Where is One-Handed Operation Setting?
P.s.:In the last rom that I used is present and work very well:
I don't know if is Note 3 or S5 mode
I think he hasn't put that feature bcoz he has to keep the rom light...and one hand operation in all screens is usually heavy on ram so i think that feature is diabled
