Android 6.0 Marshmallow had been released for more than one year, Xiaomi Mi4 still ruins Android 4.4 OS. What is Xiaomi doing in the past year? Won’t Xiaomi consider upgrade MIUI?
Xiaomi does consider so. MIUI team is working hard and now has prepared MIUI 7 based on Android 6.0 for Xiaomi Mi4. Xiaomi even jumps over Android 5.x to Android 6.0.
The version of MIUI 7 for Xiaomi is MRA58K, MIUI version is 5.11.0 developer one.
It is hopefully MIUI 7 based Android 6.0 will be pushed to users massively in the near future.
