What is Smart Stay on Samsung Galaxy S4?

Smart Stay is a feature on the Samsung Galaxy S4 smartphone that uses the front-facing camera and advanced facial recognition technology to detect whether the user is looking at the screen or not. This innovative feature allows the device to automatically adjust the screen brightness and prevent it from dimming or turning off while you are actively looking at it. Smart Stay utilizes the front camera to monitor your eyes and ensures that the display stays on as long as you are engaged with the device.

How Does Smart Stay Work?

Smart Stay utilizes the front-facing camera of the Samsung Galaxy S4 to detect your face and track your eye movements. When enabled, the device constantly monitors your eyes to determine if you are actively looking at the screen. The facial recognition technology analyzes your eye movements and maintains the screen’s brightness and visibility accordingly.

This feature is particularly useful when reading or viewing content on your device for an extended period. Instead of having to frequently touch the screen to prevent it from turning off, Smart Stay keeps the display active as long as your eyes are focused on it.
