In the video, a person is holding two cell phones in their hands. The person is using the phone on the left to unlock the phone on the right. The phone on the left has a black screen with a white lock icon in the center. The phone on the right has a colorful screen with a sunset background and a lock icon in the center. The person swipes their finger over the lock icon on the left phone, and the screen on the right phone unlocks. The person then swipes their finger over the lock icon on the right phone, and the screen on the left phone unlocks. The person repeats this process several times, showing how the phones can be unlocked using the other phone.
