Problem using WebCamTexture.videoRotationAngle on Android

I'm trying to use the videoRotationAngle property to correct the webcamTexture orientation on an multiplatform app.

 WebCamTexture.videoRotationAngle
 public int videoRotationAngle;
 
 Description
 Returns an clockwise angle (in degrees), which can be used to rotate a polygon so camera contents are shown in correct orientation.

It works fine on iOS, but on the Android devices I've tested, the videoRotationAngle property always returns 0 no matter the orientation of the device. Do I need to specify any permission for Android platform?
