Bug: App Orientation Does Not Return to Portrait on Exiting Full Screen Mode

[MudasirHussain72]

After exiting full-screen mode in the video player, the app fails to revert to portrait orientation as expected. Instead, it remains in landscape orientation, causing a disruption in user experience. This issue needs to be fixed to ensure consistent and smooth transition between full-screen and normal modes.
