Unity 5.6 Google Cardboard Camera Movement Issue

So recently my team upgraded our google cardboard project from Unity 5.4 to 5.6.0f3. In 5.4 our scripts that we attached to the camera allowed us to move the camera's position, but not rotation (obviously this is VR you don't want your camera rotation being changed). In 5.6 scripts attached to the camera move it in the editor, but not in the build on the phone. But, if the camera is a child of a GameObject you can use it to change both the rotation and position of the camera. Using this workaround we can get all of our old scripts to work, but I just want to know why this was changed (assuming it's not a glitch) and why there is a difference between the editor and build versions.
