MIUI

MIUI (which stands for Mi User Interface and pronounced "Me You I", a play on the common abbreviation of the words user interface as UI),[1] developed by Xiaomi, is a stock and aftermarket firmware for smartphones and tablet computers[2] based on the Google Android operating system.[3] MIUI includes various features such as theming support.[4]

Xiaomi has released various smartphones, all but one of which come pre-installed with a complete version of MIUI.[5] This includes various apps and features not available in the aftermarket version of MIUI.

Other than supporting their in-house smartphones and tablets, Xiaomi also offers MIUI to be flashed on other smartphone brands such as Samsung, Sony, HTC, BLU, OnePlus and Nexus.
