Can't replace default splashscreen

@ondralukas1010 and @malmazan: Do you both have the same problem, where the splash screen does not appear on Android 12 (or 13) devices?

Is there any chance you could send me your APK so I can try it on my Android 12 device?

We’re trying to determine whether this is a problem which only affects certain devices.

After uninstalling, rebooting, reinstalling: same as before.

Info from the phone:

bump - we’re still interested in this.
