Samsung Galaxy S26 Ultra is an impressive smartphone. While it may not offer significant upgrades over last year’s Samsung flagship, the S25 Ultra — with the primary enhancement being the advanced Snapdragon 8 Elite Gen 5 processor designed for Galaxy devices. Nevertheless, it introduces a feature that’s catching attention in the tech world: the Privacy Display capability of the S26 Ultra.

A noticeable variance exists in screen appearance before and after enabling Privacy Display regarding brightness and pixel sharpness. However, even when Privacy Display is turned off, the screen remains marginally dimmer in comparison to other Samsung devices, including last year’s Galaxy S25 Ultra.

When your smartphone screen displays an image, every pixel emits light at a broad angle, enabling visibility from various directions. The Privacy Display of the S26 Ultra functions at a hardware level whereby activating the mode alters the physical behavior of the pixels. The S26 Ultra’s display consists of two types of pixels: standard wide pixels that can be seen from any angle and specialized focus pixels that emit light straight ahead. When Privacy Display is activated, all wide pixels are deactivated, allowing only the other set of pixels to operate.

Unfortunately, this results in some drawbacks even when the feature is not in use. This is due to half of the pixels on the device’s screen having subpar viewing angles. Even with Privacy Display turned off, the S26 Ultra appears dimmer when viewed from certain angles because it effectively
