Where can I find the Smart Stay feature?

[AC Question]

I have a Galaxy Grand Prime running on 5.1.1. I have been trying to find the Smart Stay feature for months, but could not find it. My quick settings screen doesn't have it, and I have searched extensively, vut no luck. Hoe do I enable this feature WITHOUT rooting or a third-party app? Key word: WITHOUT!

Welcome to the forums. Have you tried in settings - my device - smart screen?
