How do I get the back button to light up?

[AC Question]

I can't see the back button on my Samsung note 4 phone. What function should I use to turn it on

Hello. Welcome to Android Central.

I shouldn't really answer this as I have a Note 3, but try Device - Display - Touch Key Light Duration; and having Power Saving on would probably stop them as well.

Any Note 4 owners?

Turn off Power Saving mode if you have it on.
