Samsung's New Galaxy S26 Ultra Has a Screen That Blocks Nosy Neighbours — But Is That a Security Feature?

The phone's built-in privacy display is a neat hardware trick. What it can't do is protect the data sitting behind the glass.

Key points

  • Samsung launched the Galaxy S26 Ultra in 2025 at £1,279 / $1,299, making it the company's most expensive current handset.
  • The phone includes a first-of-its-kind privacy display built directly into its 6.9-inch screen, designed to stop nearby strangers reading what's on it.
  • The device ships with four rear cameras, a built-in stylus, and AI — artificial intelligence — features woven throughout the software.
  • Physical privacy features do not protect against the most common ways personal data actually gets stolen from phones.

Samsung's Galaxy S26 Ultra, first reviewed by The Guardian Technology, has a trick that no other phone currently offers: a privacy display baked straight into the screen itself. Think of it like the tinted film people stick on laptop screens in coffee shops — except it is part of the glass, activated at will, and there is no film to peel off or bubble.

The idea is simple. Tilt the screen toward anyone sitting beside you on a train and they see nothing. You see everything. Shoulder surfing — the low-tech habit of craning over someone's shoulder to read their messages or banking app — is older than smartphones. This is a hardware answer to it.

It works. And it matters more than it might sound.

People in open offices, airport lounges, and hospital waiting rooms routinely expose sensitive information to anyone nearby without realising it. A privacy screen removes that risk for the moments it counts.

But here is the thing worth keeping in mind: physical snooping is not how most phone data gets stolen.

So what do people actually need to worry about?

The realistic threats to the data on your phone are software-based, not optical. Phishing — where criminals send fake text messages or emails designed to look like your bank or a delivery company, hoping you tap a link and hand over your login details — accounts for a huge share of consumer account takeovers. Malicious apps, meaning fake or hijacked applications that silently harvest your passwords or messages, are another steady source of harm.

A privacy screen stops zero of those attacks.

Samsung's AI features, which the company embeds across the S26 Ultra's camera, notes, and messaging apps, also deserve a clear-eyed look. AI tools that process your photos and messages can be genuinely useful. They can also create new questions about where your data goes and who can access it — questions Samsung answers in its privacy settings, but that most buyers never read.

None of this makes the S26 Ultra a bad phone. By all accounts it is an exceptional one. Four cameras, a built-in stylus, long battery life, and a privacy display that actually does what it says: that is a serious piece of hardware.

Just do not let the clever screen lull you into skipping the basics. Keep your operating system updated, treat unexpected links in messages with suspicion, and check which apps have access to your microphone and location. Those habits protect you from the threats the glass cannot see.
