Starting last week, owners of the Mi 3 (China Unicom/China Telecom) and the Mi 4 could upgrade their OS to the new MIUI 6. Today, Xiaomi announced in MIUI’s official forums that closed-beta tests for the MIUI 6 with the Mi 3 China Mobile Edition will start this week. Users can sign up for the “closed beta fanclub” online. Based on the progress with the other phones, we can expect open beta tests after two weeks around Mid-Autumn.
