Samsung has introduced a significant Linux kernel upgrade in the One UI 8.5 beta, shifting from version 6.6.77 to 6.6.98 to enhance device stability and responsiveness. This change, spotted in a leaked build for Galaxy S25 devices, accompanies new customization options in the LockStar module. Early feedback highlights improved animations and touch response.
Samsung's latest beta for One UI 8.5, based on Android 16, features a kernel update that promises notable performance boosts. Tipster Ice Universe identified the upgrade in a CZAA build intended for Galaxy S25 testing, marking Samsung's first kernel advancement during beta phases. The revision from 6.6.77 to 6.6.98 includes over 20 incremental updates, focusing on system stability and fluidity.
Testers have observed tangible benefits, including smoother animations, quicker touch responses, and overall enhanced user interface performance. As the kernel serves as the essential link between hardware and software, this update could support long-term device reliability.
Alongside the kernel change, Samsung launched LockStar 8.5.00.8, expanding unlock animation choices to Slide, Expand, Spread, Wave, Warp, and Ripple. Users of full-screen models like the Galaxy S24 and S25 can now manually adjust Always On Display brightness, overriding auto-settings for better battery management or visibility.
Beta 3, released earlier this month, resolved issues such as lock screen glitches, gallery lag, and battery drain from specific apps. The kernel alignment follows Google's Longevity GRF guidelines, which mandate post-launch kernel support for Android devices.
Samsung plans another One UI 8.5 beta soon, with a stable version expected alongside the Galaxy S26 series. This could integrate with upcoming features like privacy display technology, AI-enhanced weather visuals, and Bixby AI improvements, bolstering Samsung's 2026 flagships.
