Samsung eyeing a new Galaxy Book lineup will ditch ChromeOS for Google’s Android‑based AluminumOS, according to a SamMobile report. The lineup could span low, mid‑range, and flagship models, positioning Samsung to compete directly with Windows‑based laptops. This shift marks a significant change in Samsung’s laptop software strategy for consumers worldwide.

The underlying OS will run Android 17 with a One UI 9 skin, giving users Galaxy‑phone‑like features on a desktop. Rumors suggest the laptops might use Qualcomm’s Snapdragon X Elite or Samsung’s own Exynos processors for heavy‑lifting. Android Central and Android Police have highlighted these possibilities in recent leaks for the next generation of users.

Google’s I/O 2026 keynote on May 19 is the first event where the company could unveil AluminumOS in depth. Sessions slated for May 20 will cover Android, Chrome, and XR, but the main speech is expected to reveal consumer‑focused updates. Samsung’s presence could signal a broader partnership to reshape the laptop market and drive ecosystem growth.

By moving away from Chromium‑based ChromeOS, Samsung could broaden Android’s reach beyond phones and tablets. The company’s new laptops would offer a consistent UI across devices, potentially simplifying app development for developers. Samsung’s shift could redefine the Windows‑free laptop market, forcing competitors to reconsider their operating‑system strategies and accelerate innovation.
