Since the end of last month, MIUI has kept its promise to upgrade its models one by one to MIUI 9 stable version, but it is pity that the first batch is only available for Xiaomi MI6 and Xiaomi MI MAX 2. Now one week passed, there are three new models to support MIUI 9 stable version, they are Xiaomi MI Note 3, Xiaomi MI5X and Redmi 4X.
Until now, there are five Xiaomi smartphones which can be upgraded to MIUI 9 Stable version, as fast as lightning.
On July 26, Xiaomi official releases MIUI 9 OS, on the second day they start the push for developer version. On September 8, MIUI finished the last batch upgrading in two weeks in advance, including Xiaomi MI2, Xiaomi MI2S and others including 50 models in total.
