Android Pie’s source code was uploaded to AOSP last week after the final release for Google Pixel devices and Essential Phone. It means, the developer community can now start working on Android Pie to port for various devices. Luckily, abhishek987 (a Senior XDA Member) has ported Android 9.0 for Xiaomi Mi A1. Of course, the users can wait for the official roll-out, but it’s not good all the time for a mid-range device like Xiaomi Mi A1.
For example, the Essential Phone is the only non-Google device to get Android Pie final update so far. Users with other phones like OnePlus 6, Nokia 7 Plus and Xiaomi Mi Mix 2S are still on Android P beta build.
In term of development, Xiaomi is quite popular in the XDA forum because of its affordable price range. Xiaomi Mi A1 (device code-name: tissot) finally got Android 9.0.0 Pie AOSP update from the XDA. Since the phone is Android One, we expect more updates in the future with improvements. This firmware is near stable and is good enough for daily use.

What is AOSP ROM?
AOSP aka Android Open Source Project, which is a Google published Android OS without any kind of modification. All the Google devices and Android One phones come with AOSP ROM. However, some Android One phones like Mi A1 have some OEM software like Mi Remote or Camera App. So this firmware is purely AOSP, a naked Android for Xiaomi Mi A1 based on Android 9.0 Pie.
