Has he got an option to register on the phone to Samsung services, register the phone on that, fakes won't have it. Like create a Samsung account. China and Google don't go well together, hence no Play Store and such. Has it got all the Samsung logos, front, back, battery, serial number. Proper functioning TouchWiz? Check the camera, go into settings make sure it's got the full 13MP. It should have motion control and such can't see why the Chinese model wouldn't have that.
