Why you guys use outdated sources? You should look deep into mi forum cause that link is from July, and they already updated the information related to this, not stating anything specific for RN8 and the rest of devices that still don't receive miui 12 up to now. 👀
RN7 was in second phase, yet I did not receive the update. Tired of waiting. They keep promising things and don't follow through. Very disappointed. Friends keep asking me about my phone and I tell them not to waste their money.
