The video likely worked due to its visually appealing and unique design of the phone, combined with the satisfying action of peeling off a protective film, which is a common ASMR trigger. The leaf design is aesthetically pleasing and the demonstration of the phone's interface adds a functional element.
Summary
The video shows a person peeling a protective film off a phone that has a leaf design on the back. The phone is then shown with its home screen displayed, which also features the leaf design as the wallpaper. The phone is rotated to show the back again, and the video ends with a swipe gesture.

Product placement
Apple: it merely APPEARS — a corner watermark, a channel or studio logo, an end card, a credit, a name on clothing, a repost stamp. Removing it would not change what happens in the video.
