Samsung’s upcoming Galaxy S27 Ultra could finally let you hide a single private app on your screen without darkening everything else. While Samsung set the industry benchmark with hardware-level privacy display technology on the Galaxy S26 Ultra to block shoulder surfers, Xiaomi’s new 18 Pro series introduced a clever software twist that only dims one app at a time – and Samsung is already eyeing it for its early 2027 flagship.
According to prominent tech tipster Ice Universe on X, Samsung plans to adopt this selective split-screen privacy mechanism for the Galaxy S27 Ultra.
Selective app dimming for safer multitasking
The feature allows users to apply hardware privacy protection to only one app window in split-screen mode, while keeping the second app fully visible at normal brightness. As you drag the split-screen divider to resize your apps, the dimmed protection zone dynamically adjusts its borders in real-time to fit the exact dimensions of the secured application.
Below you can see the feature in action on a Xiaomi 18 Pro:
This dynamic adjustment fixes a major real-world multitasking headache. For example, you can run a sensitive banking portal or a private messaging app right next to a web browser or video player without dimming your entire display. It is worth nothing that Xiaomi and Samsung use completely different display technologies underneath. However, Ice Universe notes that Samsung still holds a clear advantage in sheer privacy screen strength and raw dimming power.
Closing the feature gap with Xiaomi
Despite Samsung’s hardware edge in screen dimming levels, Xiaomi currently leads in general software diversity and the wide variety of privacy tools that the user offers. Bringing dynamic split-screen protection to the Galaxy S27 Ultra directly addresses this software gap.
More and more smartphone manufacturers are turning hardware-level screen dimming into a standard flagship requirement. So, software flexibility looks like the next big battleground. If Samsung pairs its top-tier panel dimming power with Xiaomi’s clever window controls, the Galaxy S27 Ultra could deliver the most complete privacy setup on the market.
