In the video, a person is holding a Samsung smartphone in their hand. The phone's screen is turned on, and the person is using their finger to swipe across the screen. As the person swipes, a constellation of stars appears on the screen, and the person continues to swipe across the screen, causing the stars to move and change. The person's finger movements are smooth and deliberate, and the constellation of stars appears to be responsive to the touch. The video is shot in a well-lit room, and the focus is solely on the phone and the person's hand.
