You know the feeling: you're on a packed train, checking your bank balance or typing a password, and you can feel the person next to you reading over your shoulder. The old fix was a stick-on privacy film — a plastic sheet that dimmed your screen for everyone, including you, permanently. Samsung's answer on the Galaxy S26 Ultra is better: a privacy filter built into the OLED panel itself, and you can switch it on and off whenever you want.

How it works

The S26 Ultra's display uses Samsung's Flex Magic Pixel technology — the panel has two kinds of pixels. Wide pixels spread light in every direction, like a normal phone screen. Narrow pixels funnel light straight at your face. Flip on Privacy Display and the wide pixels dim down, leaving mostly the narrow ones: crystal clear for you, and from the side the screen drops to about 3.5% brightness at a 45° angle — effectively a blank slab to anyone but you. It works in portrait and landscape, from every side, and barely touches battery life because it's redirecting light, not generating more of it.

Turn it on

  1. Swipe down from the top-right corner to open the Quick Panel, and tap the Privacy Display toggle. That's the fast way — on in two seconds, off just as fast.
  2. Or go to Settings → Display → Privacy Display for the full controls. Left on with no tweaks, it simply stays active until you toggle it off.
  3. Make it automatic per app: in the same menu you can pick specific apps — your banking app, for example — so privacy mode kicks in whenever they open, and stays off everywhere else.
  4. Hide notification pop-ups too: there's a setting to keep incoming notification previews private, so a text preview can't leak across the aisle even with privacy mode on.

The smart bits

  • Auto on for sensitive moments — you can set it to engage whenever you're entering a password or PIN, then drop back to normal.
  • Maximum Privacy Protection — a stronger setting that further cuts side visibility when you really don't want eyes on the screen.
  • Per-section privacy — because it works at the pixel level, it can dim just parts of the screen, like the notification shade, while the rest stays normal.

One tradeoff to know

Maximum privacy mode trims brightness slightly, so it's worth switching off when you sit down to watch video. And unlike a stick-on film, there's no permanent cost: toggle it off and the display is back to a normal wide-viewing-angle OLED. That's the whole point — privacy when you want it, a great screen the rest of the time.

Read the screen. Now look from the side — that's the entire demo.
