MIUI

MIUI is a deprecated mobile operating system developed and used by Xiaomi for its smartphones and mobile devices from 2010 to early 2024, prior to the launch of its successor Xiaomi HyperOS. MIUI was based on the Android Open Source Project. Xiaomi produced versions for Xiaomi-branded smartphones and its own Poco, MIUI Pad, MIUI Watch, and MIUI TV (PatchWall). There are different versions for each Xiaomi phone model, and each version has regional variants dependent on where the phone is sold, including China, Europe, Indonesia, India, Japan, Pakistan, Russia, Taiwan and Turkey. Xiaomi also released a few devices running Google's Android One instead of MIUI. Xiaomi devices usually receive three Android version updates, and MIUI updates for four years (less for budget models). The first MIUI ROM, released in 2010, was based on Android 2.2.x Froyo and was initially developed in China by Xiaomi in its first year of operation. Xiaomi added a number of apps to the basic framework, including Notes, Backup, Music, and Gallery apps. An organisation named Xiaomi Europe, using the domain xiaomi.eu and working officially with Xiaomi despite not being affiliated with the Chinese company, was set up in 2010 as a community for English-language Xiaomi users with phones running MIUI, and later HyperOS, associated with an Android version. xiaomi.eu makes available for free download debloated and improved ROM images based on China MIUI and HyperOS ROMs. Installing these images is technically challenging.
