Igeekphone 3/4: Tech media Android Authority published a blog post yesterday (March 3), stating that during the MWC 2026 exhibition held in Barcelona, Samsung showcased the next-generation privacy screen technology. This is another significant evolution following the first introduction of this feature in the Galaxy S26 Ultra.
In terms of the working principle, Samsung has equipped the screen of the Galaxy S26 Ultra with two different types of subpixels: one is the narrow-angle subpixel, which can only be seen from the frontal view; the other is the wide-angle subpixel, which can also be seen from the side.
In normal mode, both sub-pixels operate simultaneously. Once the privacy screen function is activated, the wide-angle sub-pixels will be deactivated, thereby restricting the visibility of the side view and ensuring that the screen content is only visible to the user.
Igeekphone reports that on the current S26 Ultra model, users can choose to enable the privacy mode in full screen, or set it to automatically activate when accessing specific applications, viewing notifications, or entering a password.
Based on the above practical scenarios, Samsung further expanded the application of its technologies. The next-generation technology demonstrated at MWC is no longer limited to small areas such as the notification bar, but also supports more flexible application to specific areas of the screen. It can cover a larger area of the screen, for example, automatically hiding the input content when the virtual keyboard is called.
Samsung has clearly stated that this breakthrough relies on a new generation of hardware and cannot be achieved by software updates for the existing screen of the S26 Ultra. Although this foldable phone technology may not be available this year, it is widely speculated that the Galaxy S27 series next year is very likely to be the first to feature this upgraded privacy protection function.
