What is mysterious eye icon that appears and disappears?

[Android Central Question]

The eye icon that appears on top of phone and flashes in an out is called smart stay. When i scroll down from top of phone and it shows all the features with location and wifi i saw this icon for first time and was able to turn it off. I looked it up it said its a feature that watches you to make sure you are still looking at device so it will keep the screen on.

Welcome to Android Central, and thanks for the tip! Yep, that's a feature on Samsung phones.

LG too. You have to remember to move a bit from time to time to let the phone know that you are still alive.
