One-handed input, only the dialing keypad and in-call buttons (Not Samsung keyboard)

Hi All,

I am using Note 4. I really want to use on-handed input only the dialing keypad and in-call buttons. But there are NO options to select it.
Is there any way to turn ON One-handed input only the dialing keypad and in-call buttons NOT Samsung keyboard?
Please help me.
Thank you so much!
Jae
