Samsung has started working on the next major version of its own Android-16 -powered software skin. Early beta builds of One UI 8.5 suggest that the company is exploring kernel changes to support long-term performance gains . If implemented, it could also improve the responsiveness, long-term stability, and overall user experience of the software.
Samsung’s One UI 8.5 kernel update may improve Galaxy long-term performance
According to the popular tipster Ice Universe, a recent One UI 8.5 beta build includes an upgraded Linux kernel . A leaked CZAA build reportedly moves the Galaxy S25 Ultra from kernel version 6.6.77 to 6.6.98. To give you an idea, this change represents more than twenty incremental kernel revisions. Though such changes are often invisible to the users, they could boost performance, long-term stability, and responsiveness of the user interface.
Moreover, such a high jump is very unusual, especially in the beta versions. This hints that Samsung is considering upgrades beyond visuals and UI design in the coming version. Newer kernel versions typically include security patches, bug fixes, and refinements to resource management. However, they do not automatically guarantee a better performance and stability.
Performance gains reportedly noticeable
Google’s Longevity GRF rules mandate Android manufacturers to deliver several kernel upgrades after the launch. However, in the case of Samsung, the company is testing the newer version even before the official launch. This might indicate that the tech giant is preparing for a broader internal change.
The tipster has further claimed that the performance gains are already noticeable. The UI has a visible improvement in terms of animations, touch response, and better overall fluidity during daily use. Samsung is expected to release another One UI 8.5 beta later this month. The stable release and the launch are expected to happen alongside the debut event of the Galaxy S26 series. If implemented properly, the upgraded kernels could boost the long-term reliability and performance of Samsung devices.
