When I lock the phone in landscape mode then rotate it phone to rotation_270 (i.e landscape clockwise) the preview image on the camera stays upside down.
But in portrait mode, the app adjusts the image so that when I rotate the phone "upside down" the image is still right side up.
As a user I'd expect the camera behavior to be consistent between the two modes (landscape/portrait). This one is more about consistency between how landscape and portrait behave.
