Brutal.

The video likely worked due to its aesthetic appeal and the use of a popular, visually striking dark theme on a smartphone. The single word "Brutal." creates intrigue and encourages viewers to watch further.

The video shows a hand holding a phone with a dark theme and various app icons. The word "Brutal." is displayed prominently on screen. The phone's operating system, Xiaomi HyperOS, is then shown, along with its version information.

Xiaomi HyperOS: it is the operating system on the phone. It merely APPEARS. Removing it would not change what happens in the video. Xiaomi 17T: it is the phone model. It merely APPEARS. Removing it would not change what happens in the video.
