MIUI 11.0.3 for the Redmi K20 comes in at 700 MB while MIUI 22.214.171.124 for the Redmi 7, Redmi Note 7 and Note 7 Pro also brings the September security patch. MIUI 11 is a fairly big overhaul with refined visuals including a system-wide dark mode, new dynamic sounds effects and alarms as well as the Mi Go Travel and Mi Work suites.
Naturally, the Chinese version of MIUI 11 comes without Google services as is the norm in the country. International users will get their update at a later date, but hopefully it's not too far away now.
As previously confirmed by Xiaomi, we should expect a lot more Xiaomi devices to get MIUI 11 in the coming weeks.
