Permanently remove Splash Screen

Hello folks,

I’m struggling with removing splash screen (beacuse I want to have animation on the start). What I did:

1. npm uninstall --save @ionic-native/splash-screen
2. ionic cordova plugin rm cordova-plugin-splashscreen
3. <preference name="SplashMaintainAspectRatio" value="true" />
<preference name="FadeSplashScreenDuration" value="0" />
<preference name="SplashShowOnlyFirstTime" value="false" />
<preference name="SplashScreen" value="none" />
<preference name="SplashScreenDelay" value="0" />
<preference name="AutoHideSplashScreen" value="true" />
4. from app.module.ts I removed what was about splashScreen
5. from app.component.ts I also removed what was about splashScreen

Many times I removed and added ionic cordova platform add ios but it nothing helped

When I put ionic serve everything is ok, but on emulator and my device for the first second appears cordova logo instead of my animation.
