Yep, for real this time. The update is already rolling out; if you have not received it already then you will soon. OS update to Android 8.0 Oreo brings with itself a plethora of software improvements, such as App Pair feature, new high contrast keyboard design, Dual Messenger and Picture-in-Picture mode. Bad news is that the updated device will not receive June security updates, at least not right away.
