A few weeks ago, Xiaomi sent out early MIUI 12.5 builds to the global and European models of the Mi Note Lite and Mi Note 10/Mi Note 10 Pro respectively. The company is now expanding the rollout by providing Turkish and Russian models of the Mi Note 10 Lite with their taste of MIUI 12.5, as well Global ROM units of the Mi Note 10 and Mi Note 10 Pro.

I got it over the weekend on my newly purchased Redmi Note 9T. To be honest there is little difference between this and my last MIUI phone, the Redmi 6A from 2018.
Had to dig into a menu to find out if was actually Android 11 under it all.
