CameraPreviewScaleYandCameraPreviewScaleXproperties to the camera view and implemented updates via theUpdatePreviewScaleon the camera manager.As far as I know, this is not a problem on iOS -- only with some Android devices. I did not provide an implementation in the iOS platform-specific code.
The reason this is needed is some Android devices do not provide the correct camera orientation. Thus, the PreviewView cannot orient itself correctly to the user's perspective.
An example of this is a Microtouch IDC 15-inch tablet. The screen orientation can be manually set (no internal accelerometer or gyro), but when you do this, the camera's orientation is not changed. This leaves the camera preview upside down or sideways in some cases.
