In the video, a person is seen holding a black object in their hand. The object appears to be a phone case. The person is using their thumb to push a button on the case, which causes a light to turn on and off. The light is located on the back of the case, near the top. The person continues to press the button, causing the light to blink on and off several times. The background is dark and indistinct, but it appears to be an indoor setting. The person's hand and the phone case are the main focus of the video.
