Double splash screen with with flash in between

That is the intended behavior. The Capacitor splash screen plugin does not modify the native splash screen

What worked for me to solve the problem of having a “gap” between splash screens was 1. setting launchAutoHide to false in capacitor.config.json:

// capacitor.config.json
  "plugins": {
    "SplashScreen": {
      "launchAutoHide": false,

and 2. calling SplashScreen.hide(); just before presenting the second splash screen:

// (2nd splash)

ionViewWillEnter() {
    this.platform.ready().then(() => {
