Black areas on top and bottom of the screen

I got an issue on widescreen devices on Android when black areas appeared on top and bottom of the screen. The image is scaled down vertically a bit.

In other thread was said to add

Code (CSharp):

1. <meta-data android:name="android.max_aspect" android:value="2.1"/>

to AndroidManifest, but that didn't affect anything. We see it only on Samsung Galaxy S9 devices, but probably the rest widescreen devices will have the same result.

Any advice?
