Samsung explains how Privacy Display works on the Galaxy S26 Ultra and what controls it offers. Xiaomi has announced native hardware-level privacy protection for the Xiaomi 18 Pro series, but that announcement does not establish how it compares in use. The material available here does not verify an equivalent Huawei feature—or prove that Huawei lacks one.
What the comparison can—and cannot—establish
“Who rules” depends on what you mean by a privacy-display lead. On published documentation, Samsung is ahead: it provides operating details and setup guidance for a specific phone. Xiaomi has announced a competing display implementation, while Huawei’s comparable offering is not established by the available official documentation. None of that is a controlled comparison of privacy effectiveness.

Samsung calls its feature the first built-in mobile-phone Privacy Display. That is Samsung’s product claim, not an independently verified survey of the market. Samsung also cautions that some information may remain visible depending on the viewing environment, including angle and brightness. Neither company’s announcement, by itself, shows how well its phone protects text from someone looking over the owner’s shoulder.
What Samsung’s Galaxy S26 Ultra Privacy Display does
Samsung describes Privacy Display as an integrated feature designed to limit peripheral viewing by controlling the screen’s viewing range. The company says its Flex Magic Pixel technology controls light emission. Owners can turn the feature on manually or set it to activate in selected situations.

Controls and setup
On the Galaxy S26 Ultra, Samsung’s US support instructions give two routes to the setting:
- Open the Quick Panel, then touch and hold the Privacy Display icon.
- Open Settings > Display > Privacy Display.
Samsung says users can configure activation for selected apps, PIN, pattern or password entry, and notification pop-ups. This selective control is useful if the goal is to shield particular sensitive moments rather than keep the display restricted all the time. The feature’s precise behavior should be checked on the phone and software version being used.

Maximum privacy and its trade-offs
Samsung’s “Maximum privacy protection” setting narrows the viewing angle further. Samsung warns that this mode can dim the screen and may slightly blur the image or alter colors. The company also says visibility can vary with angle, brightness, and viewing environment, so the feature should not be treated as a guarantee that nearby people cannot see the display.

What Xiaomi has announced
In a Xiaomi Community global announcement dated September 21, 2026, Xiaomi said the Xiaomi 18 Pro series’ Super Pixel 2.0 screen includes “native hardware-level privacy protection.” The announcement also mentions an M11 light-emitting system, new green light-emitting materials, and a full RGB pixel arrangement.

This establishes that Xiaomi has announced a privacy-oriented display implementation; it does not provide a measured comparison against Samsung. The announcement alone also does not establish broad retail availability across markets or regional versions. Details about app groups and sensitive-page triggers appear in screenshots and secondary information associated with the announcement, so they should not be treated as a fully documented, independently validated feature specification.
What is established about Huawei
The available official material does not establish a Huawei phone feature directly comparable to Samsung’s Privacy Display or Xiaomi’s announced hardware-level protection. That is a limit of the evidence, not proof Huawei has no such feature. Availability and support can vary by phone model and region, so a categorical brand-wide conclusion would require current, region-specific Huawei documentation.

How to judge a real privacy-display winner
A fair verdict requires the exact phones and software versions to be compared under the same conditions. A useful assessment would check:
- Side-angle legibility: At what viewing positions does sensitive text become difficult to read, and does the effect hold at different brightness levels?
- Straight-on readability: How clear, bright, and color-accurate is the screen for its owner with protection off and on?
- Selective control: Can users target chosen apps, credentials, or notifications, or does the protection apply to the whole screen?
- Image trade-offs: Does turning on protection dim, blur, or shift the display? Samsung specifically documents possible changes in maximum-privacy mode.
- Model and regional availability: Which retail models and regional software versions actually include the feature?
No independently published head-to-head test or comparable benchmark is established here. Without one, calling a device the most effective would go beyond the evidence; even a privacy display should not be assumed to block every possible view of the screen.

Do you still need a privacy screen protector?
A smartphone privacy screen protector is a physical retrofit to consider for a compatible phone without an integrated privacy-display feature. Check that the protector is made for your exact model, since fit and compatibility matter. Samsung says its built-in feature removes the need for an additional protector on the Galaxy S26 Ultra and warns that third-party privacy protectors may reduce brightness on that phone. That brightness warning is Samsung’s guidance for its device, not a universal measurement for every protector or handset.
