Samsung has released a short video demonstrating the Galaxy S26 Ultra's new privacy display feature, which can make the screen appear black when viewed from the side. The technology allows for either full-screen or selective area blacking out without affecting the primary user's view. This Zero-peeking privacy toggle represents a significant advancement in mobile security.

Last month, Samsung first teased this "new layer of privacy" for its upcoming flagship device. The video reveals that the phone has per-pixel control over the privacy feature, enabling selective blocking of notifications or specific content areas. This granular control offers users more flexibility than traditional privacy screens that typically only work in one mode.

The privacy display technology addresses growing concerns about visual hacking and shoulder surfing in public spaces. By allowing users to maintain screen visibility while preventing side-angle viewing, Samsung aims to enhance security without compromising usability. The feature's selective capability suggests potential applications beyond basic privacy, such as protecting sensitive information in specific apps or during particular tasks.
