The Samsung Galaxy S series has been a mobile phone hallmark for 16 years now. The Korean tech giant has brought mobile phone innovations such as OLED screens, large displays, and foldable devices. This year, Samsung’s new flagship phone, the Galaxy S26 Ultra, introduces an innovation we’ve never seen before: the Privacy Display. This feature supposedly protects the contents of your phone from prying eyes while appearing as a normal display to the user.
Award-winning privacy
At the recently concluded Global Mobile Awards held at the Mobile World Congress 2026 in Barcelona, the Galaxy S26 Ultra won the prestigious Best in Show award for its blend of hardware, software, and privacy. According to the chair of the judges, the phone innovates in privacy and meets the important needs of today’s digital lifestyle. It is available now and has an immediate application to consumers and to the future of privacy technology.
So, how exactly does Privacy Display work? Leveraging Samsung’s display expertise, it uses a new type of OLED display called “Flex Magic Pixel“. The first time it was showcased was at MWC two years ago. According to Samsung Display, a conventional panel maintains around 40% of its front-facing brightness even at an angle. This makes it easy for prying eyes to read your sensitive content. Meanwhile, the new panel is modified to separate the Black Matrix, which controls light diffusion by separating red, green, and blue sub-pixels. This creates a multi-layer structure that blocks light at specific angles. The layer is combined with a new, more power-efficient OLED technology to complete the panel, enabling two display pixel types: wide and narrow.
In standard use, both wide and narrow pixels combine to provide a wider viewing angle, like a typical phone display. When privacy mode is enabled, the wide pixels dim or deactivate depending on the setting. Meanwhile, the narrow pixels direct light forward, making it almost impossible to read from an angle. UL Solutions, a global safety science company, concluded that a 45-degree side angle reduces brightness to 3.5%. Meanwhile, a 60-degree angle reduces it to 0.9% with the privacy mode enabled. One great use of the feature is that users can choose to enable it only for certain apps, such as email and messaging, to hide content in public, or even enable it only for notifications pop-ups. At the same time, the rest of the display remains in standard mode.
Testing the Privacy Display option
It just so happens that I upgraded to the Galaxy S26 Ultra and was able to test out the Privacy Display. In my experience, the technology is just as advertised. Unlike the usual hit-or-miss AI features and software, the new display technology actually works really well. In standard mode, it looks just like any other modern OLED display, with viewing angles similar to my old Galaxy S23 Ultra. When enabling the feature, it works a lot like a privacy screen protector one can buy in the market right now.
Turning on Privacy Display allows me to browse my phone normally. For anyone trying to look over my shoulder, that’s another story. When tilting the phone, the brightness becomes obscured as the content and text become harder to see. Tilting it further makes the screen completely illegible. The technology really works like something out of a spy movie, and it’s incredible that it’s on a product that will be available for millions right now.
Use cases of the feature
There’s an option to enable Privacy Display only for certain apps, and I think this is a much better use of it. I have it enabled automatically for work emails and messaging apps, while I can watch YouTube content without sacrificing visual fidelity or brightness. Another feature is that you can only enable it for notification pop-ups, which is also very helpful. You can still use the phone without sacrificing your vision, but notifications are obscured for anyone who isn’t staring directly at it.
The last option for Privacy Display is Maximum Privacy Protection mode. This adds a blue-ish hue to the whole interface, but makes it impossible to read or see any content on your screen from the sides, even at a slight angle. This is truly a last-ditch option, as it’s a significant sacrifice to visual quality when enabled.
While the display certainly gets darker and resolution drops when Privacy Display is enabled, it’s still a much better option than buying a privacy screen protector. For the latter, not only are you sacrificing the display’s vibrance and brightness, but it’s also a permanent solution. In my opinion, the trade-off of enabling it is fine. After all, you don’t really need maximum resolution or full vibrance when reading sensitive emails. The technology already works very well, and it should improve in future iterations. Personally, the display is really good when the Privacy Display is off. It’s still very usable in the standard privacy mode.
Too tall a promise?
The Galaxy S26 Ultra’s Privacy Display is a true innovation we haven’t seen in a mobile phone in a while. This new display is not as foolproof as the usual tried-and-tested displays are, however. According to some users, text and content appear noticeably fuzzy when compared side by side with the previous Galaxy S25 Ultra, even with the privacy mode turned off. It’s too early to conclude whether this is just an effect of the technology, a one-off, or a truly noticeable difference.
As smartphone technology has stagnated, all we get every year are faster processors, larger and brighter displays, and better batteries, with less innovation and an over-reliance on AI features—a common criticism, especially of Apple and Samsung. The same criticism also applies to the Galaxy S26 series, with online users of previous models not seeing any reason to upgrade, and the higher prices being another point of contention.
Despite the online criticism, this doesn’t seem to affect the bottom line. Counterpoint recently reported that the Galaxy S25 series outpaced the S24 series in sales, despite similar online negativity. Time will tell whether these potential issues are true showstoppers for the popular phone line or whether the Privacy Display feature is enough to bring in more users. In today’s tech landscape, there is widespread concern about privacy, data leaks, and scams. Technologies such as this can be very helpful in protecting users.
