Find out what OS the device is running.
As the demand for iPhones rises, scammers are getting better and better at creating really good knockoff devices. They’re able to replicate the form factor to be almost identical to the real deal.
A good way to test whether a used iPhone is a fraud is to check what OS it’s running by turning it on. There have been cases of used “iPhones” running Android, a dead giveaway that the device is a clone. But this might be tougher to identify, as a Motherboard reporter found out with a counterfeit iPhone X. We suggest interacting with the device’s UI, like opening the App Store and initiating other Apple-specific functionalities, just to be sure its running iOS.
