The S26 Ultra introduced what Samsung calls Flex Magic Pixel technology, which blacks out the display when viewed from side angles without requiring a physical privacy filter. A dedicated one-click switch toggles between modes, and the display can also detect when someone is looking over the user's shoulder and alert the user. Huawei also draws a direct comparison with Samsung's implementation. A promotional slide for the MateBook Pro S shows that, in privacy mode, the Lingdun panel maintains 100% pixel utilization, while what it labels the "S-brand phone pixel design"—an apparent reference to the Galaxy S26 Ultra's Flex Magic Pixel technology—operates at 50% pixel utilization in the same mode. The trade-off on Samsung's side is a reduction in brightness and resolution when privacy mode is active; Huawei claims its single-zone dual-pixel architecture avoids this penalty entirely.
