Android 11 is almost ready to arrive on another dozen devices like the Xiaomi Mi A3, according to a new report. The Mi A3 is Xiaomi's only Android One handset that is eligible for Android 11, as the Mi A1, Mi A2 and Mi A2 Lite have already received their allotted two OS upgrades. Other devices supposedly scheduled for Android 11 include the global Redmi Note 9 Pro and Redmi Note 9 Pro Max.
