In the video, a man is seen sitting at a table with a smartphone in front of him. He is holding a screwdriver in his right hand and is using it to tap on the phone. As he taps, the phone starts to vibrate and eventually, the screen lights up. The man then proceeds to tap on the phone again, and this time, the screen lights up even more brightly. He continues to tap on the phone, and the screen becomes increasingly bright until it is fully illuminated. The man seems to be testing the responsiveness of the phone's touch screen.
