Samsung has recently announced that the highly anticipated Galaxy S26 Ultra will be the pioneering model to incorporate the “Privacy Display” function. Building on hardware-level advancements, this function employs Magic Flex Pixel technology to precisely manage the direction in which pixel light travels. While ensuring top-notch display quality for the user facing the screen, it significantly narrows the side viewing angle to almost negligible levels, effectively thwarting “shoulder surfing” attempts in public settings. In real-world scenarios, tests have demonstrated that screen clarity, color accuracy, and brightness remain unaltered during regular usage. However, when viewed from the side, the content on the screen becomes nearly imperceptible, even at the highest brightness setting. At the software level, Samsung's One UI offers intelligent assistance, enabling users to designate specific apps to automatically activate the anti-peek mode. Alternatively, users can enable smart activation based on location and time parameters. For instance, the protection mode can be set to automatically engage in office environments. Developed over a span of more than five years, this innovative feature heralds a new era in mobile privacy protection. It effectively addresses the limitations of traditional physical privacy filters, which often compromise display quality, and software-based solutions, which can be easily circumvented.
