MIUI (pronunciation: Me You I) is a heavily modified software skin for Android developed by Chinese electronics manufacturer Xiaomi. This is a fork of the Android OS. MIUI includes various features such as theme support.
Xiaomi has released some smartphones with Android One while others have MIUI, based on the current version of Android. Xiaomi devices usually get one Android version update, but get MIUI updates for four years.
The first MIUI ROM was based on 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 the basic framework, including their Notes, Backup, Music, and Gallery apps.
MIUI and Google Play services
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 Android
Although the MIUI is built on the Android platform, the default user interface of its earlier iterations 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. By 2018, MIUI was increasingly shifting towards a design aesthetic more similar to the stock Android. For instance, several elements in the MIUI 10 build resemble Android Pie features 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 difference from Android is the MIUI's support for themes and custom fonts. Users can download theme packs and fonts, which can change the user interface of the device once installed from the Mi Themes Store. It 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. Source code for certain components was released to GitHub on 25 October 2013. Kernel sources for a few devices, including the Mi3, Mi4, MiNote, and Redmi 1S, were released in March 2015.
In order to raise funds for the company, MIUI has its own online services from Xiaomi, including cloud services, paid themes and games. Payments are transacted using the MiCredit digital currency.
In April 2019, security researcher Arif Khan reported that Xiaomi's browser apps Mi Browser and Mint Browser suffered from a vulnerability that allowed the URL address bar to be spoofed, which affected Indian as well as certain global versions of MIUI. Xiaomi gave Khan a bug bounty but opted not to fix this issue. In addition, a vulnerability in a wallpaper carousel app Glance on Indian versions of MIUI allowed a user to bypass the lock screen and access clipboard data. This vulnerability was eventually fixed by Xiaomi.
