We have a cardboard app that starts into a non-VR menu in portrait orientation. When the app goes into VR, we change the orientation and enable VR. With the external Google VR SDK this was possible. However, with native VR in Unity 5.6 set to Cardboard, the android app is forced (in the AndroidManifest) to start up in landscape left orientation. We can change the orientation after startup, but this still leaves the ugly screen rotation animation when starting up and the splash screen is rotated as well. Is there any way to force a Native VR Cardboard app to start in portrait orientation?
