Gray screen berofre splash screen on Android

Ionic Framework
1

Good afternoon. For some time now I have been trying to optimize my splash screen, however, every time I open the app a gray screen appears for about two seconds. Researching I found that this screen is actually the beckground of the splash screen on android. How do I make the app open directly on the splashscreen without showing this screen? And if it is to show, is there a way to set the transparent background?

<preference name="ScrollEnabled" value="false" />
<preference name="BackupWebStorage" value="none" />
<preference name="AutoHideSplashScreen" value="false" />
<preference name="SplashMaintainAspectRatio" value="true" />
<preference name="FadeSplashScreen" value="true" />
<preference name="FadeSplashScreenDuration" value="2000" />
<preference name="ShowSplashScreenSpinner" value="false" />
<preference name="SplashShowOnlyFirstTime" value="false" />
<preference name="SplashScreen" value="screen" />
<preference name="AndroidLaunchMode" value="singleTask" />
