Samsung Galaxy S26 Ultra: Innovations and Challenges of the Privacy Display

At the recent Galaxy Unpacked 2026 event in San Francisco, Samsung unveiled the Galaxy S26 Ultra, featuring a notable innovation called the Privacy Display. This technology is designed to provide pixel-level protection against unauthorized viewing, commonly referred to as "shoulder surfing." Unlike traditional privacy screen protectors, the Privacy Display can be activated for specific areas of the screen or the entire display, regardless of whether the phone is in portrait or landscape mode.

Samsung Display showcased advancements in the Privacy Display technology at the Mobile World Congress in Barcelona. Demonstrations included prototypes that allowed for larger sections of the screen to be obscured, indicating ongoing efforts to enhance this feature. While the current implementation is effective, the company aims to refine the technology further, potentially allowing users to select specific areas of the screen to hide. However, it remains uncertain whether Samsung Electronics will integrate these developments into future models, such as the anticipated Galaxy S27 Ultra.

Initial testing of the Galaxy S26 Ultra has revealed that the Privacy Display feature impacts screen brightness significantly. The device's peak brightness is recorded at 1,806 nits, slightly lower than the Galaxy S25 Ultra's 1,860 nits. When the Privacy Display is activated, brightness can drop dramatically; for instance, with Maximum Privacy Protection enabled, brightness can plummet to as low as 586 nits, representing a 67.6% decrease in light output. This reduction can make the screen challenging to view, particularly in bright environments.

While the Privacy Display offers a unique solution for privacy concerns, it comes with trade-offs. Users may find the screen dimmer and less vibrant, especially when the feature is active. Critics note that this could detract from the overall viewing experience, as the display appears less bright even in indoor settings. However, the ability to toggle the feature on and off allows users to reclaim a brighter display when privacy is not a concern.
