The screen of the Redmi Note 14 Pro 5G can not stay on when you look at it. The feature you're referring to is known as Gaze detection. It allows the device to keep the screen on as long as it detects that you're looking at it. This helps prevent the screen from turning off while you're reading or interacting with it, providing a more seamless using experience. It works by using the front camera to track the movement of your eyes, ensuring the screen stays active while you're engaged with the device.
Although the Redmi Note 14 Pro 5G does not include this function, you can manually adjust the screen sleep time to extend the screen's activity time as needed.
