Serial number and model number not match
hello. I would buy a private ipad mini 4. The guy send me photos and there is a ipad mini 4. But when i verifying the serial number from setting it look like it is a ipad 4 generation. When i verifying the model number from setting it look like it is ipad mini 4. On the back case, the serial number it is for ipad mini 4.
what is wrong? Why the serial number and the model number from setting not mach for same ipad device?
