New Linux Kernel in One UI 8.5 willsignificantly speed up your Samsung device

While recent leaks regarding the upcoming One UI 8.5 interface have largely focused on visual redesigns and expanded external hardware support, it appears Samsung is orchestrating significant improvements where it matters most—the system’s foundational architecture.

Until now, community attention has centered on aesthetic tweaks and user controls. However, the latest reports suggest the South Korean giant is working on serious performance optimization through a major upgrade to the operating system’s kernel.

A Major Leap in Kernel Versions

According to information shared by the reliable industry insider known as Ice Universe, Samsung has implemented a newer version of the Linux kernel in the latest beta builds of One UI 8.5.

Specifically, in a test build (identified as “CZAA”) for the Galaxy S25 Ultra, a jump was observed from Linux kernel version 6.6.77 to 6.6.98. While this may look like a string of random numbers to the average user, it represents a leap of over 20 sub-versions. According to the source, this shift could result in a noticeable difference in interface fluidity once the software is released to the broader public.

What Does This Mean for Performance?

It is important to note that a kernel upgrade does not necessarily guarantee a dramatic spike in synthetic benchmark scores. However, a newer kernel typically delivers:

• Enhanced Security: Patches for vulnerabilities at the core system level.

• Better Resource Management: More efficient allocation of processing power and memory, which indirectly boosts performance.

Through its Longevity GRF program, Google requires Android OEMs to provide regular kernel updates, but the mandate only covers three upgrades post-launch. The fact that Samsung is taking this step so early suggests a proactive approach.

It is possible that Samsung is preparing the ground for a more extensive system overhaul to enable backward compatibility (backporting) of new features debuting with the upcoming Galaxy S26 series to older devices.

Tangible Improvements in Daily Use

The theory regarding better performance is supported by the leaker’s own experience. Ice Universe notes a clear improvement in the phone’s responsiveness on the test device. This includes:

• More precise and faster touch response.

• Smoother system animations.

• General fluidity when navigating menus.

These changes are expected to be implemented in the fourth beta version of One UI 8.5, which is slated to reach users later this month.

When Will the Stable Version Arrive?

The official release of the stable One UI 8.5 is expected to coincide with the launch of the new Galaxy S26 smartphone series next month. While the new kernel will likely become the standard for a wider audience, the rollout pace will, as always, depend on the specific device model and the user’s region.
