In the video, a person is holding a smartphone in their hand. The phone is turned on and the screen is lit up. The person's thumb is visible, and they are using it to swipe across the screen. The phone appears to be a modern smartphone with a touchscreen interface. The person's thumb moves smoothly across the screen, suggesting that the phone's touchscreen is responsive and easy to use. The video does not provide any audio or additional context, so it is unclear what the person is doing on the phone or what application they are using.
