Hello, Question about Splash Screens on Android.

Hello, Question about Splash Screens on Android.

On a Galaxy S5 (1080 x 1920) the splashscreen is the 470x320 picture (why ?)...but the image is truncated, how is it possible ?

I've tried to use 9patch image, the top and bottom is no more black, but the image still truncated

The picture is the screenshot of the phone with the original picture over (the 470x320 text was on the phone, that's how I know wich picture is used)

Apparently the image is displayed at 300% of the original.
