The Mi A1 is Xiaomi’s first Android One phone, which is actually the Mi 5X but with pure Android. If you own the Mi 5X and want to experience pure android, there is a ported ROM of the Mi A1 available for download. What if you own the Redmi Note 4/Note 4X? There is also a ROM for you.
XDA senior developer, GLokin666 has ported the ROM of the Mi A1 to the Redmi Note 4/4X. The ROM is based on version 7.9.21 of the Mi A1 and is sort of an alpha/beta build as some features such as the fingerprint scanner and infrared scanner are not working. There are also some camera features missing. However other features work well and Gapps come pre-installed. It also comes with September’s security patch and supports for multi-language.
If you want to give it a try, you can download it from the source page below. If you are also a developer, you can also give it a try and help fix the fingerprint scanner and IR blaster.
The Redmi Note 4/4X is different from the Mi A1 in terms of design and specs, however they both share the same Snapdragon 625 processor and have 5.5” FHD displays.
