If the Android One program was to allow compatible smartphones to benefit from quick updates to later versions of Google's system, it has not always been the case. Today, few are still compatible smartphones to have been updated to Android 9.0 Pie.
It is therefore worth noting the performance of Xiaomi who not only has already updated its Mi A2, with Android One but has just started the deployment of the latest version of Google's OS on its previous smartphone, the Xiaomi Mi A1, as reported by one of our readers.

As can be seen on the screenshot, the arrival of Android 9.0 Pie also signs that of new features among which the FM radio, the brightness, and battery adapted to the use, the gestural navigation or various recommendations in context function.
To update your Xiaomi Mi A1 to Android 9.0 Pie, simply go to the settings of your smartphone: system => advanced options => system update => check for updates. If no update is available, you may have to wait a few days before receiving the latest version of Android.
