Splash screen ratio and multi screensize support mobile

Is there a way to get the Unity splash screen (pro) to not stretch or distort for different mobile device screen sizes?

I think the texture needs to be power-of-two size. Meaning it has to be 256x256, 512x512, 1024x1024, etc. I’m not sure if it has to be square. However, I got it working when using a 1024x1024 texture for my splash screen.

Yes, center only I think (but it will be cut off in that case)

However, as mentioned, you have to set your texture first!
-find it in the project tab and select
-not set it from texture to advanced
-switch of nearest power of two and apply

(Only then the image is saved with the right aspect ratio)
