MIUI 10 may be the latest version of Xiaomi’s custom UI, but that doesn’t mean that MIUI 9 has become obsolete. In fact, it will take months for Xiaomi to release Global Stable and China Stable ROMs for its devices. The company has already specified the roll-out schedule for MIUI 10 Global Beta, as well as MIUI 10 China Alpha. An important thing to note, however, is that a MIUI 10 update is separate from an Android Oreo update, as MIUI 10 ROMs can be based on older versions of Android.
After a gap of a few months, Xiaomi has now released Android 8.0 Oreo-based MIUI 9.6 Global Stable ROMs for the Xiaomi Mi 5, Xiaomi Mi Note 2, and the Xiaomi Mi Mix. The download links are noted below:
