Splash screen is not removed on iOS

When app is started, splash screen remaines open. If I push app to background and open it again, splash screen is removed.
Also spinner is placed to the upper left corner instead of center.

App does work properly on some iPhones - e.g. I have no troubles with that on iPhone 4 with iOS 9.3.5

Splash as said in docs removed in js:

onDeviceReady: function() {
app.receivedEvent('deviceready');
setTimeout(function()

{ navigator.splashscreen.hide(); }

, 2000);
}

Preference in config as said in docs:
<preference name="AutoHideSplashScreen" value="false"/>
