Android 13 black bar on top bug

[sheesh3178]

Device model: Realme C51
Android version: Android 13

Problem:
Just like all the older apps, this one doesn't support full immersive mode for newer versions of Android, and unfortunately this particular phone I own doesn't let you hide the black bar no matter what. There's just no option for it and even ADB failed on me due to the apparent changes on Android 11. The problem is apparently because of the front camera existing.

The app itself should be able to achieve full immersive mode because the newer apps and especially games can.
