It does not bring any additional debloating or added features/apps: what you see on the Mi A1 is what you’ll get on the Redmi Note 4. This port was developed by XDA Senior Member GLokin666, and as the name says, it’s pretty much a barebones port of the Xiaomi Mi A1 firmware for the Redmi Note 4 phones (not like that’s a bad thing!). After a successful port for the Xiaomi Mi 5X, we’re now getting an Android One port for the Xiaomi Redmi Note 4 and Redmi Note 4X. And because it’s officially supported firmware rather than a custom ROM, the developer community has set out to port the Mi A1 firmware to other, MIUI powered Xiaomi devices.

The Mi A1 is the first of such “global Android One” phones, and it’s also coincidentally the first phone ever made by Xiaomi using close-to-AOSP software. With the release of the Android One-branded Xiaomi Mi A1 and the Moto X4, and the upcoming HTC U11 Life, Google seems set on delivering a no-frills, Google-supervised stock Android experience with a more global focus and big hardware partners like Motorola and HTC.
