Gray blank page on starting Ionic app on android

Hello guys,

I’m sure all of you guys have observed this short gray blank screen which shows up when starting an ionic app on android.
It looks like this gray screen can’t be removed? is there a way to permanently remove this gray screen?

I finally figured out a way to completely remove splash screen and white blank loading page.
I replaced them with a custom made HTML page with css animations.

Now it’s only left to remove this gray screen to make my ionic app start like any other app built on Java or C#.

Please let me know if you guys know how to get rid of this useless gray blank screen on start up.
