Fake Device Test is an application that can detect if a device is fake or not. The device that is tested needs to have modified firmware, which needs to be hidden from the user. The device's firmware is what determines its hardware specifications. It can be modified to report a false or inflated hardware specification, which can be used to scam people. 

This app will detect the modified firmware by running a series of tests. It will send a report of the results to the user, who can decide if the device is real or not. The user needs to download this app, and then he or she can run the tests. The user needs to make sure that the device is not in a corrupted state and is not damaged.
