In the video, a person is holding a smartphone in their hands and using their thumbs to swipe across the screen. The phone is displaying a colorful image of a fish swimming in water. The person's thumbs move back and forth across the screen, causing the image to move in a similar manner. The phone appears to be a modern smartphone with a large screen and a black bezel. The person's thumbs are visible, and they are wearing a white shirt. The background is blurred, but it seems to be an indoor setting with neutral colors.
