There are some Bugs. If you set to darken the wallpaper in display options, wallpaper becomes dark if darkmode is on, but when it goes back to bright mode, the wallpaper keeps dark. LED is still flashing even DND mode is on, even the preinstalled light/dark wallpapers only change their colors when you reboot the phone. Force dark mode on apps is also not working, you can't update system apps you can't update play security updates and so on. I am waiting so impatiently for A14 custom ROM to get rid of this MIUI ROM...
beside from that its a stable rom
