Splash screen not change image on rotation

I have an android app with different splash screens based on dpi and orientation.
When I launch the app the correct dpi and orientation is selected: if I start in portrait it starts with the portrait version, if I start in landscape it starts with the landscape version.
But if I start in portrait and rotate the device during splash screen, the image rotates but it not swap to landscape version, simply stretch the portrait image to fit width and height.
