Xiaomi gave the surprise a few months ago when it presented its new mobile with Android One, the Xiaomi Mi A1, abandoning its Android layer to collaborate with the Google initiative. Now the community is taking the system to other mobile phones of the brand and so can you.
A few months ago there was already success with the Android One ROM port for the Xiaomi Mi 5X. The 5X and the A1 are, in essence, the same mobile in terms of specifications, so the adaptation of the operating system could be done without major complications.
However, now we find the Xiaomi Redmi Note 4, a smartphone whose hardware does differ from what the Xiaomi Mi A1 offers. This leads to some technical difficulties that we will see later. The first step, like so many other times, is that you have your mobile rooted. If you don't know how to do this, you can learn in our Android root tutorials.
So you can install Android One on the Xiaomi Redmi Note 4
Once your phone is rooted, download the Android One ROM and place it on your phone, no matter if it is the internal or external memory. If you have problems with that link, you can use this other one. Once this is done, reboot your phone in recovery mode.
When you are in the recovery mode, select the ROM and it will begin to install. The process will take a few minutes and once completed, your Xiaomi Redmi Note 4 will start up with Android One as if you had a Xiaomi Mi A1.
Yes it is true that the port is not perfect, so you will lose two functions. The first is the fingerprint sensor, which will stop working properly. The second is the infrared sensor, which won't work either. This is due to hardware differences between the devices, although the same developer or other people may be able to fix the bugs in the future.
Otherwise, you can enjoy a pure Android experience. The ROM is multilanguage and comes with several of Google's applications. The last security update of this version is that of September 2017, the month of departure of the Xiaomi Mi A1.
You can see the ROM installation and how it works in the following video. If you want to try it for yourself, remember that some functions are not 100%, so keep that in mind before launching.
