Xiaomi is secretly developing a self-made operating system akin to Huawei’s HarmonyOS that will be compatible with AOSP (Android Open Source Project), as per a Weibo source on Tuesday. AOSP is a Google-maintained project for open-source OS development. Through AOSP, developers can craft an OS that is installable on Android-compatible devices. Xiaomi’s forthcoming system is anticipated to function on various devices such as smartphones, tablets, cars, and watches. Concurrently, sources have noted Xiaomi’s registration of the domain name mios.cn on November 11, 2022. Currently, mios.cn is in a 403 state. [IFeng, in Chinese]
