Android

The Google-developed, Linux-based, open-source mobile operating system powering billions of devices globally.

Android is the world's dominant mobile operating system, developed by Google and built on the Linux kernel. First released in 2008, it quickly established its open-source platform (AOSP), enabling massive hardware diversity across OEMs (Samsung, Xiaomi, etc.). The platform currently commands a significant global mobile OS market share, serving over three billion monthly active users. Its reach extends beyond smartphones and tablets: dedicated versions power smart TVs (Android TV), cars (Android Auto/Automotive), and smartwatches (Wear OS).
