OnePlus’s Android 12-based OxygenOS 12 update has finally reached "stable" status. That’s a label that means it shouldn’t be particularly buggy and that it’s rolling out — in this case, to the OnePlus 9 and OnePlus 9 Pro. But if you’ve been following customer impressions, the new release seems to be anything but stable, and the new software takes some noteworthy (and negative) departures from prior OxygenOS releases. More plainly: OxygenOS 12 is awful and feels like budget phone software on the thousand-dollar OnePlus 9 Pro.
