I have written a new module https://github.com/sean6541/op9_series_camera_unlocker that is a huge update to this one. It is fully scripted and should (no guarantees) work on all versions of OOS and custom ROMS using OOS FW and continue to work with future updates. It also unlocks face detection and (optionally) 48MP full resolution. Please see the README for the new module before installing it as it contains important instructions and information.

Magisk module that unlocks all cameras for use by third party apps on the OnePlus 9.

Using a post-fs-data.sh script, the module copies the /odm/etc/camera/CameraHWConfiguration.config file to it's (the modules) directory and then uses sed to replace the line SystemCamera = 0; 0; 1; 1; 1 with SystemCamera = 0; 0; 0; 0; 1. This un-sets all the cameras as system cameras, which means that third party apps can access and use them. It then sets the SELinux context of the edited copy of CameraHWConfiguration.config and mount --bind's it to the original (necessary because Magisk doesn't support overriding files in the odm partition).

1. Download latest op9_aux_cam_enabler.zip from releases page: https://github.com/sean6541/op9_aux_cam_enabler/releases

3. Reboot

Notice: This module will ONLY work on the OnePlus 9 (non-pro). It will not work on ANY other device. If you have a OnePlus 9 Pro, use this module instead: https://github.com/sean6541/op9pro_aux_cam_enabler
