Xiaomi released the latest update for the Xiaomi Mi A1 smartphone (review) last summer, leaving it on the Android 9 Pie operating system. However, enthusiasts have not abandoned the once popular smartphone and have released a new unofficial ShapeShiftOS firmware based on the latest Android 11.

At the end of January, Xiaomi Mi A1 also introduced another firmware based on Android 11 — POSP (Potato Open Source Project). Now users of the legendary smartphone have a choice in what form to install Android 11.

The ShapeShiftOS firmware is based on the Android Open Source Project (AOSP) and, according to the developers, its goal was to «provide a user interface and experience unlike any other firmware on the market.»

Among the advantages of ShapeShiftOS, ease of installation, Google services and applications included, customizable clock from Android 10, numerous appearance settings are mentioned. Among the shortcomings — the lack of updates «over the air», the lack of illumination of the touch buttons, the lack of additional wallpapers. Another feature is that the Camera app is used in the Go version, which has both pros and cons.

Recall that the smartphone debuted in September 2017 as part of the Android One program — the device does not use the proprietary MIUI shell, but a «clean» version of Android.

It not only became the first Android One phone, but also proved to be very successful. In the fourth quarter of 2017, the Xiaomi Mi A1 was not just the best-selling Android One smartphone, it sold two and a half times better than all other devices in the program combined.
