Xiaomi has published a rather odd update for the Redmi Note 8. The update is another Android 10 and MIUI 12-based build for the device, but it is a debut update for the European branch of MIUI. It is unclear why Xiaomi has established a new branch of MIUI for the Redmi Note 8, but it has published download links for the inaugural build.
