• Hardware/ROM Dependent: The success of this app depends entirely on your device's specific ROM and manufacturer restrictions. If your device’s firmware does not support these hidden menus, the app will display an error message. We kindly ask for your understanding that this is a system limitation, not an app bug, before leaving a negative review.
• Enhanced Security: To protect your device from malware and unauthorized modifications, this app is designed to work safely only when installed directly from the Google Play Store. Sideloading from unknown sources will trigger a security block.
