Rear View of Man Looking at Smartphone with Chroma Screen

A young adult with short, dark hair holds a smartphone horizontally. The phone displays a green screen, ideal for compositing. The individual is indoors, seated at a desk in a brightly lit room, possibly an office or educational setting with white tables and muted walls in the background. The shot is a close-up, focusing on the phone and hands. The video can be used for demonstrating apps, software interfaces, or mobile gaming. It's suitable for tech reviews, tutorials, and promotional content that requires a customizable screen display.
