Xiaomi has begun testing builds of the MIUI proprietary shell based on the new Android 12 operating system among its users. The launch of the beta version of MIUI 12.5 based on Android 12 for the flagship Xiaomi Mi 11 was reported by several sources at once.
So far we are talking about closed testing among a very small number of selected people in China. Since this is the Chinese version, you won’t find Google services and apps here, and the language support is limited to English and Chinese.
Also, since this is an early stage of development, some features may not work fully or may not work at all, although they are available in MIUI 12 / MIUI 12.5 builds based on Android 11.
Of course, enthusiasts are already offering to download and install this assembly for those who regret it, but you should do this solely at your own peril and risk, knowing full well what you are doing and what you may encounter.
Earlier versions of Android 12 without MIUI shell have already been tested on Mi 11 Ultra and Mi 11i, Mi 11X Pro and Redmi K40 Pro smartphones. So we can hope to see MIUI 12.5 based on Android 12 for these models soon.
