Hi,
perhaps i'm wrong but i remember i had similar problem. You could try to add these values to your android styles.xml file:

	<style name="XXX" parent="Maui.MainTheme.NoActionBar">
		<item name="android:windowBackground">@color/YYY</item>
		<item name="android:windowIsTranslucent">false</item>
		<item name="android:windowTranslucentNavigation">false</item>
		<item name="android:windowTranslucentStatus">false</item>
	</style>

You have to replace name and perhaps parent with your values. Also "android:windowBackground". I'm not at work atm so i can't say exactly which item could help.

Good luck.
