A. 1. Check app permissions: Go to 'Settings' > 'Apps' > 'AniDub Max' > 'Permissions' and ensure it does not have permissions that allow it to control brightness. 2. Disable battery saver: If your device has a battery saver mode, try disabling it to see if that resolves the issue. Go to 'Settings' > 'Battery' > 'Battery Saver' and turn it off. 3. Restart your device: A simple restart can sometimes resolve issues with app behavior.
