When vuforia is enabled in Unity 2017.3, even when Default Orientation is set to Portrait, the loading screen is forced to landscape for a while.
The attached loading1.jpg shows the screen is portrait when just clicked the app icon.
The attached loading2.jpg shows that the unity loading screen is rotating clockwise to landscape mode.
The attached loading3.jpg shows that after unity loading, our splash screen is show up by rotating counter clockwise to portrait mode.
Anyone has idea about this? Why is Unity loading forced to portrait when loading? Thank.
