I can't clearly understand the problem well, but you can try adding SplashScreen in createStackNavigator() in navigation.js file

const StackNavigator = createStackNavigator({
    loginScreen: { screen: Login },
    splashScreen: {screen: SplashScreen},
    { 
        initialRouteName: 'splashScreen',
    }
})
export default createAppContainer(StackNavigator);

In your App.js file replace with this:

const App = () => (
  <Nav />  //instead of SplashScreen
);
