How to Hide White Splash Screen in Ionic 3 - SOLVED

By default, the splash screen is hidden after 3 seconds (see https://github.com/apache/cordova-plugin-splashscreen#configxml). But it could be that at this moment your app is not ready.

Therefore I add always the following preference to my config.xml:

<preference name="AutoHideSplashScreen" value="false">

Instead, I hide it manually, as soon as the app is ready:

this.platform.ready().then(() => { Splashscreen.hide(); });

This is working on iOS as well as on Android.
