Samsung leads on documented detail, not proven performance. Samsung describes a built-in Privacy Display on the Galaxy S26 Ultra and explains how to configure it. Xiaomi has announced native hardware-level privacy protection for the Xiaomi 18 Pro series, but the available announcement does not establish comparable test results or broad retail availability. The available material does not verify an equivalent Huawei feature. No evidence here supports naming a performance winner.
What the privacy display comparison can establish
The clearest distinction is between what each company has documented and what has been independently measured. Samsung provides feature and setup details for the Galaxy S26 Ultra; Xiaomi has announced a competing hardware-level approach for its Xiaomi 18 Pro series. Neither source establishes how the two perform against each other under identical conditions.
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 viewing conditions, including angle and brightness. Samsung’s announcement

Samsung Galaxy S26 Ultra: documented controls and trade-offs
Samsung says the Galaxy S26 Ultra’s Privacy Display is integrated into the phone and uses Flex Magic Pixel to control light emission, limiting visibility from side angles. The feature can be switched on manually or configured for selected apps, credential entry, and notification pop-ups. Samsung Support’s feature and setup guidance

Samsung’s announcement states that the feature “controls the screen’s viewing range to limit peripheral vision.” It also warns that “some information may still be visible to others depending on the viewing environment, such as angle or brightness.” These are manufacturer statements, not a guarantee that shoulder-surfing is prevented.

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

This establishes that Xiaomi announced the feature; it does not establish independently measured privacy performance or a broad global retail rollout. Details about app groups and sensitive-page triggers appear in screenshots and secondary information within the announcement, so they should not be treated as a fully documented, validated feature specification.

The available sources do not verify an official Huawei phone announcement or support page describing a directly comparable privacy display. That is not evidence that Huawei has no such feature. A meaningful comparison would require checking Huawei’s current models and region-specific documentation; no Huawei performance claim can be supported here.

How to judge a real performance winner
A fair head-to-head comparison would need to test specific models under the same conditions rather than rely on feature names or announcements. The useful questions are:
- Side-angle legibility: At what angles does sensitive text become difficult to read, and does that remain true at different brightness levels?
- Straight-on readability: How clear, bright, and color-accurate is the screen for its owner with the feature off and on?
- Selective control: Can protection be limited to chosen apps, credentials, or notification surfaces, or does it apply across the whole screen?
- Image trade-offs: Does privacy mode dim, blur, or shift colors?
- Availability: Which exact models and regional software versions include the feature?
No comparable independent results or viewing-angle measurements are established here. Samsung’s own warning that visibility depends on conditions is a reminder that a privacy display should not be treated as a guarantee against someone seeing sensitive information.

Do you still need a privacy screen protector?
A compatible smartphone privacy screen protector remains an option for a phone without an integrated privacy display. Check that the protector fits your exact model and consider its effect on screen brightness. Samsung says third-party privacy screen protectors may reduce brightness on the Galaxy S26 Ultra and says its built-in feature removes the need for an additional protector.
