Few days back, Xiaomi released the Android 6.0 Marshmallow based MIUI China stable ROM for Mi 3, Mi 4, and Mi Note in China. And today, the company has rolled out the Global Beta stable version of MIUI 7.3.17 based on Android 6.0 Marshmallow.
The stable ROM can be installed on Xiaomi Mi 3, Mi 4 and Mi Note units outside China. Since, it’s a Global ROM, it will be packed loaded with Google apps like Google Play Store, Play services and more.
However, you should have an international variant of the phone in order to install the update. Xiaomi is working hard to bring the update to as many devices as possible, so you’ll have the country specific ROM soon.
