The video shows a close-up of a person using a small metal tool to scratch a design into the back of a white smartphone. The person starts by drawing a circle and then proceeds to make lines inside the circle to create a design. The smartphone has a camera lens and a flash on the top left corner. The person's hand is visible holding the tool, and they are wearing a yellow rubber band on their wrist. The design appears to be a simple pattern of lines within the circle.
