Galaxy S26 Ultra Privacy Display proves there’s still room for hardware innovation in phones

In 2026, we feel like we’ve seen it all in phones, right? Powerful processors, unreasonable amounts of RAM, incredible displays, wild designs, and even foldable phones.

Granted, there’s still room to grow in that foldable / rollable / who-knows-what-follows segment. But the ordinary “chocobar” phone hasn’t surprised us recently.

What is the Galaxy S26 Ultra Privacy Display?

At its core, it’s inspired by privacy screen protectors — glass panels with limited viewing angles, so whenever you have one on your phone, anyone looking at your screen from the side will see nothing but black.

The issue with traditional privacy screen protectors is that they offer privacy all the time. That has obvious benefits, but it’s also their biggest flaw. A physical privacy screen inevitably degrades image quality — it can make your screen appear dimmer, alter colors and viewing angles. And since they are permanent, you cannot just peel them off to show show some photos to your friends, or even when you just enjoy your content on your own.

Well, Samsung had a thought — what if we integrate the privacy aspect within the screen panel and make it possible to toggle it on and off at will. You can easily switch it on while reading your texts on the subway and then turn it off when showing photos to your friends or watching video on your own.

How does it work?

The Galaxy S26 Ultra’s Privacy Display is built directly into the screen panel. Within the panel, there are two layers of pixels. One layer has the “regular” build with pixels meant for wide-angle viewing. The second layer has a black grid woven in between its individual pixels.

When not in use, that grid is lowered and does not change the way the screen looks or operates. But when you activate Privacy Display, the grid’s walls are raised, blocking the light of its pixels from leaking off to the side, essentially focusing them forward.



While this is happening, the main wide-angle layer’s brightness is dropped drastically, but it remains on to keep things vibrant and looking somewhat “normal”.

This blocks out a lot of the screen content when it’s viewed off from the side. Prying eyes will mostly be seeing the black walls of the grid, instead of the light coming from the isolated pixels.

This is particularly useful when you are reading your personal messages on the subway, checking your bank account at a cafe, or opening your travel details at a busy airport. Instead of a display that’s easy to see from all sides, Privacy Display narrows the viewing angles.

Samsung also gives users a Maximum Privacy Protection setting. This will narrow the viewing angle even further and lowers the brightness, making content even harder to see from the side.

The trade-off is that when you do this, color liveliness and contrast drop. It’s assumed that if you are looking at something sensitive, like your banking app, PIN number, or private chat, you don’t care about contrast at the moment. Privacy is king here.

It’s also worth remembering that Samsung has a broader approach to privacy not limited to just the display. The Galaxy S26 Ultra also uses Samsung Knox, a platform that protects sensitive data on both hardware and software levels.

Knox helps secure your passwords, biometric data and files, plus features like Secure Folder let you keep private apps behind an extra authentication layer. This way, Knox works in the background to protect your privacy, and the Privacy Display handles the problem of someone looking over your shoulder.

The best part - it can be automated

Since Privacy Display is baked into the Samsung panel and controlled by the Samsung software, you can fine-tune One UI to automate it. Within the Privacy Display settings screen, you can tell the phone to toggle it on whenever you open a specific app.



So, as mentioned above, you can have it auto-engage every time you open your e-banking, which makes perfect sense for a feature like this.

Additionally, the black grid can only be engaged in a certain area of a display. I have it turned on for notifications — the screen literally reduces the viewing angles around notification bubbles every time they come in.



No matter whether I am on a train or in the store, nobody can see my chat messages with an accidental glimpse off from the side.

I also have Privacy Display set to always engage when I open my digital wallet for mobile payments. I just don’t want to accidentally flash my account balance to anyone in the store, and that feature gives me some extra peace of mind.

Of course, use common sense. But also, use my special privacy booster hack, outlined below.

Extra tip: use Samsung Routines

As I mentioned above, you can definitely set up Privacy Display to turn on automatically for specific apps — it’s an easy toggle within the Privacy Display section of Settings.

However, I found that the blackening effect is further improved if you lower your screen’s brightness. So, I cooked up a specific routine for my banking app.

Go into Settings -> Modes & Routines -> Routines. Create a new routine.



In the “If” section, select event “App opened” and mark your banking app. Press done.



In the “Then” section, choose “Add”, look up Display -> Privacy Display and choose to have it “On”, “Maximum Privacy Protection”.



One more time, in the “Then” section, press “Add action” and go to Display -> Brightness. Choose the target brightness by using the slider.

I set it down to 7% — I find this brightness level is still plenty visible to me thanks to the anti-reflective properties of the Gorilla Armor 2 screen. Yet, it enhances the effectiveness of Privacy Display quite noticeably.

By default, everything should be back to normal when you leave the app. If it’s not, check your “When routine ends” conditions.

What’s next?

By all accounts, it seems like the Privacy Display is a complex and expensive feature to build into the phone. Which is why it will probably be an exclusive to the Ultra line for a good while.

Will someone else try to do it as well? But it’s a huge undertaking, and we do know that Samsung has the vertical integration (Samsung Electronics, Samsung Display) to make it possible. Others? Not so much. But time will tell.
