Xiaomi has released various smartphones, all but Mi A1, A2, A2 Lite and A3 of which come pre-installed with a complete version of MIUI. Xiaomi devices usually get one Android version update, but get MIUI updates for four years. This has made various apps and features not available in the aftermarket version of MIUI, but available only through rooting.
On February 24, 2016, Xiaomi said that the MIUI ROM had over 160 million users worldwide, and was supported on over 677 handsets.
The original MIUI ROMs were based on the Android 2.2.x Froyo and was initially developed in the Chinese language by Chinese startup Xiaomi Tech. Xiaomi added a number of apps to enhance the basic framework; those include Notes, Backup, Music, and Gallery. MIUI used to be translated and ported into unofficial versions in other languages by independent developers and groups of fansites. There are still unofficial ports being made but their popularity decreased after Xiaomi released their own cell phones. Updates are usually provided over-the-air every Thursday (CST).
MIUI and Google Play ServicesEdit
Google has had disagreements with the Chinese government, and access to many Google services is blocked. MIUI does not ship with Google Play Services in mainland China. However, Xiaomi has expanded its operations outside China; MIUI releases for Android devices outside mainland China have Google Play Services and Google Apps such as Gmail, Google Maps, Google Play Store pre-installed and functioning as on any other Android device. MIUI global versions are certified by Google.

MIUI vs. AndroidEdit
Although the MIUI is built on the Android platform, the default user interface of its earlier iterations closely resembled iOS due to the absence of the application tray with a grid of icons arrayed in the home panels. Other iOS similarities include the app icons being in a uniform shape, the dialer and in-call interface, the organization of the Settings app, and the visual appearance of toggles in the UI. This prompted some observers to cite how the devices running on MIUI could appeal to iOS users wanting to switch to the Android platform. Recently, however, MIUI is increasingly shifting towards a design aesthetic that is more similar to the stock Android. Reports indicate, for instance, that several elements in the MIUI 10 build will closely resemble what Android Pie has brought onto the table such as the multitasking menu and gesture controls. This change was first seen in the MIUI 9 (ver. 8.5.11) that shipped with the Xiaomi Mi Mix 2S. The MIUI firmware already looked like stock Android P.
Another key difference that distinguishes MIUI from Android is the system's support for themes. Users can download theme packs from the Mi Market, which could drastically change the user interface of the device once installed. It even allows advanced users to tweak the hard-coded firmware of their handsets.
MIUI's kernel was proprietary, and in breach of Linux kernel's GPL. Due to criticism, source code for certain components was released to GitHub on 25 October 2013. Kernel sources for a limited number of devices, including the Mi3, Mi4, MiNote, and Redmi 1S, were released in March 2015.
Since MIUI V4, based on Android Ice Cream Sandwich and Jelly Bean, Xiaomi added a virus scanning engine from partner company Tencent (formerly from Kingsoft, whose CEO appears to be the same person) despite the opposition of many users. Methods of removing it were published in the MIUI's Chinese forum, since the engine was not found to be helpful.
Also during the development of MIUI V4, Xiaomi started to remove Google Mobile Services (GMS) from their ROMs because of Chinese government policies that arose in response to Google's disagreements with the Chinese government. The government blocked access to all Google services on every platform, in mainland China, and all phones made for the Chinese market are required not to allow the installation of GMS. GMS is present in the global variant of MIUI, however.
In order to raise funds for the company, MIUI has its own online services from Xiaomi, including cloud services, paid themes and games (featuring the MiCredit digital currency).
