What does it mean to have visible navigation buttons before touching them on a Samsung phone?

[AC Question]

So I want to buy the note 5 and i don't want it to be fake but when i went and checked it i noticed that the buttons on the navigation bar are already visible even before touching them. Normally you can only see the home button and after you touch either side on the navigation bar the buttons will light up and be visible.I just want to make sure if that is a sign that the note 5 is fake .

You can set some devices to show them or not show them (to save battery)..

The touch light duration is probably set to "Always On"
