my arrow and multi bar buttons wont light up... ( besides the home button) galaxy note 4

[AC Question]

Anyone has any idea how to make it work.?

Do you have the phone set for power saving. I forget which power saving setting it is but if you select it, it will not display the two buttons you mentioned.

Go to settings, display, touch key light duration and make sure it's not set to off.
