In the video, a person is holding a black cell phone in their hand. The person is using their thumb to push the back cover of the phone up and down. The phone has a camera lens and a USB port on the back. The person's thumb is visible as they manipulate the phone. The background is blurred, but it appears to be an indoor setting. The person's hand is steady, and they seem to be demonstrating how the phone's back cover can be removed or attached.
