The Galaxy S26 Ultra’s privacy display is more interesting to me than any AI feature
The Samsung Galaxy S26 range is finally here, and after spending the past two weeks with the Galaxy S26 Ultra, one feature in particular feels like a real throwback to the company’s glory days of bold hardware innovation.
Despite the company’s increasing focus on Galaxy AI features at its recent Galaxy Unpacked event, I came to the conclusion that the most beneficial improvement of the S26 Ultra is what only AI can achieve, and that is Private Display.
How many times have you been in the crowd, maybe on a crowded train or in a restaurant, only to find out the hard way how your screen is exposed to their eyes? Whether you’re texting with a friend, doing online banking, or watching embarrassing TikTok videos, what you’re doing on your phone is no one else’s business.

But what if you just turn on a setting on your phone, and the person next to you doesn’t see anything? No awkward hand protection, no dimming your screen, just automatic privacy at its best. That’s exactly what the Galaxy S26 Ultra’s new privacy display does — and it’s the first smartphone feature in years that feels truly revolutionary.
The glory days of hardware innovation
Over the past 12 years of reviewing smartphones, I’ve had a front-row seat to the industry’s constant innovation. I’ve watched manufacturers chase bold ideas, abandon failed experiments, and sometimes come up with game-changing ideas that have truly changed the way we use our devices.
Smartphone makers used to compete with real, tangible things — the kind you can see and feel when you pick up the device, making it feel truly unique. I was there when Samsung first introduced curved “curved” displays, I saw LG’s wild experiment with the G5, and I groaned along with everyone else at HTC’s sensitive touch of pressure. I was also there for Motorola’s Moto Mods (a personal favorite), Apple’s Face ID, Huawei’s first dual-camera phone… and let’s not forget Google’s confusing thermal sensor in the Pixel 8 Pro.
These were all big waves. Some didn’t hit, some didn’t, but these hardware-based features gave each phone personality and made handset announcements more exciting. However, flash forward to 2026, and everyone is chasing the same AI features that will trickle down to every other mobile device within the year, making it hard to get excited about the future of smartphones.
That’s why the privacy display of the Galaxy S26 Ultra stands out: it’s rare to return to real hardware differentiation at a time when the industry seems content to let AI be the main draw card.
How Privacy Screen is hardware dependent
Although the Galaxy S26 Ultra’s privacy display is software-enabled, it relies on very clever hardware engineering, and it all comes down to how the individual pixels are formed on the device’s OLED panel.
Basically, the panel uses a two-pixel structure, with two OLED optical transmitters that are shaped and arranged to direct light differently. In other words, the panel can throw light with a wide emitter that looks at wide angles, or switch to a smaller emitter that projects its light more strongly. These optical products are layered directly on top of each other to prevent light from escaping from the panel at the sides, which is why this feature cannot be achieved with software alone.
When you look at the phone, you see a clear, bright image. However, if you look at it from even a small angle, the screen goes dark until nothing can be done on the screen. And unlike privacy guard-style screen protectors, the screen darkens when the phone is tilted vertically and horizontally.
Using Privacy Mode
By swiping down on the S26 Ultra’s quick panel, you can toggle the privacy mode on or off. However, tapping Privacy Mode in the phone’s settings will allow you to use certain conditions when the mode is activated.
For example, you can set Privacy Mode to only turn on when you enter a PIN, pattern or password, or when you’re inside your Secure Folder. You can also set Privacy Mode to turn on automatically when using certain apps. The privacy display mode can be set to no notification pop-ups and nothing else.
The Privacy Screen comes with some caveats
That’s not to say that the implementation of the privacy display is flawless – these extra layers have made the viewing angles on the Galaxy S26 Ultra worse, even if the mode is completely turned off. So, while the phone’s display is technically capable of the same brightness level as its predecessor (about 2,600 nits), it can appear noticeably dimmer.
The switch from wide to narrow pixels also comes with a slight reduction in resolution and brightness, resulting in a reduction in visual clarity, especially regarding text. Of course, this isn’t a big problem if you only use Privacy Mode in certain situations, such as when entering a PIN or pattern, or using certain apps.
There’s also a High Privacy Mode, all but a black screen at any angle. It works well, but I wouldn’t leave it on forever unless you’re comfortable with a clear hit on overall image quality.
More like this please, Samsung
Samsung’s Galaxy S26 Ultra is arguably one of the most advanced smartphones I’ve ever tested, boasting several forward-thinking features. I’m a big fan of the new Horizontal Lock feature for video capture, which keeps the S26 Ultra’s camera perfectly level at all times, even when you turn the phone upside down.
I also like how the AI-powered Audio Eraser feature now works in streaming apps, allowing you to manually adjust background audio levels to your liking on Netflix, YouTube and more.
Admittedly, I wasn’t able to test the S26 Ultra’s new Agentic AI features during my pre-release with the phone, but the ability to multitask and automate workflows sounds really useful if it works as promised.
Still, these kinds of AI and software features may trickle down to other phones in the future, which is why hardware-driven innovations like Privacy Mode make me so excited. It’s the kind of unique feature that no other phone has – one that would be very difficult to copy without some serious display architecture changes. And that’s exactly the kind of innovation I want to see more of from Samsung.
