While the world is still waiting for the stable Android 12 for the Pixel devices. Android 12 Developer Preview 2 is available for the OnePlus 9 series, and it brings a series of tweaks with it as well. It is essential to know that the second developer preview is released about three months after the first build.

OnePlus announced the latest update on their forums, and it does show a decent number of changes and tweaks. However, we would advise you again that these developer previews are made for people who are looking to test out the apps and features on their devices and not everyone else, because that way, you are only going to invite more issues, and that is not what we want, to begin with.
