Xiaomi has started rolling out the Android 6.0.1 Marshmallow update to its flagship smartphone, the Mi 4. The Mi Note has already received the update earlier this month and now the Mi 4 starts seeding the update. The update bumps the built number to MMB29M directly to Android 6.0.1 Marshmallow, instead of getting V6.0 Marshmallow. But Mi Note was initially updated to V6.0 and then to V6.0.1. The update shells out 100MB of device memory.
