This genuinely makes me so mad. When you Google how to make apps appear in fullscreen, the official Samsung website gives you this info. Meanwhile, with this latest ONE UI 7 UPDATE, THEY HAVE LITERALLY REMOVED THIS FEATURE. WITHOUT EVEN SAYING ANYTHING. THERE IS NO FULL SCREEN APPS BUTTON IN SETTINGS. it's GONE and now my games have UGLY BLACK BARS ON THE SIDES THAT I CAN'T GET RID OF.
