Tis the season to be jolly, Xiaomi Mi A1 users. Well, for some of you.

Xiaomi is now pushing out the Android 9 Pie update to the Mi A1. The 2017 Android One phone was long overdue to get the new software, what with Android One’s promise of speedy updates.

In early December, one user reported getting the Android 9 Pie beta to their Mi A1. Days later, an apparently stable update landed on more devices from around the world. Unfortunately, the OTA created severe problems with LTE connectivity for some users, and Xiaomi did a terrible job of explaining what’s going on.

On December 20, Xiaomi announced (via Gadgets 360) that a new Android 9 build is rolling out to users. The new firmware is called PKQ1.180917.001 (V10.0.2.0.PDHMIFK) and is apparently a full release, rather than a beta.

The main new features in the release are support for FM radio, adaptive battery and brightness, and recommended apps based on user actions.

Now for the bad news: while many users on Reddit report receiving the update with no issues, others complained about missing LTE bands. Furthermore, according to several redditors, Xiaomi appears to have halted the rollout again. We’re reached out to confirm what’s going on.
