Start from the camera setup that calls setPermissionDescriptionListener(getPermissionDescriptionListener()) in the issue, then trace how the permission description listener is handled for camera-only capture. Reproduce with PictureSelector v3.11.2 and verify that the configured permission description is displayed when the camera permission is needed.
