OnePlus is doing all the right things on the hardware side of things; the OnePlus 12 continues to be one of the best phones you can buy today, and the Open is holding its own a year after release. Software, however, is a point of contention; the last two OxygenOS releases have been buggy — even the stable versions — and it took several updates before they became usable.
OnePlus is looking to address those issues once and for all with the introduction of OxygenOS 15. The Android 15-based release includes plenty of new features, much-needed design tweaks, new privacy features, and better overall optimization. The interface isn't quite as fluid as OxygenOS 9.5, but at this point, I don't think OnePlus — or anyone else — can get to that level.
