I get something like that top left on my LG G3. It watches me and if it detects me it knows I'm using the phone and doesn't let the screen time out and switch off. It's an option in Settings, Display, called Smart Screen. Perhaps yours is something similar.

Yes, Samsung has something similar also called Smart Screen, located at Settings/Controls/Smart screen.
