I had heard that it doesn support some apps but I still bought it anyway. Below are some apps Ive been using regularly and never had any issues ES File Explorer PayTM Subway Surfer Adobe Reader Terminal Emulator There are many more but these are what I remember right now. However one small glitch was that from Greenify it could not get the needed Administrator privilege from the dialog the workaround was that you had to go to Settings=Accessibility in android and set that setting from there. In worst case if you don like the MIUI (Xiaomi version of Androdi) you can flash a CyanogenMod or one of the other ROMs available for this device. Hope that helps.
