Android
/ˈæn.dɹɔɪd/
n. — "Linux-based mobile OS enabling sideloading chaos across hardware buffet."
Android runs on modified Linux kernel with layered architecture (Kernel→HAL→Native Libraries→ART→Framework→Apps) powering 70%+ global smartphones via Google-led AOSP plus manufacturer skins. Unlike iOS's walled garden, Android supports sideloading, diverse SoCs (GPUs from ARM/Mali/Adreno), and Google Play Services for cloud sync while OEMs fragment versions/security patches across device zoo.
