LineageOS has released Android 12 for the Oneplus 9, however Wunderment 19 is going to be delayed for it.
With the move to Android 12, OxygenOS has made significant changes to the underlying system, this has created two issues:
- Many new partitions that need to be reviewed to see if they should be included, and if so, if it’s possible.
- Relocking the bootloader is currently not working.
Investigation on both issues is underway, however, for the time being, the Oneplus 9 will remain on Android 11.
Updates will be provided as more is known.
