Does Apple goes by the serial number/IMEI on the rear case or from the logic board? In this specific case, I have an iPhone 6 that has the dreaded Touch Disease, but the phone is out of warranty. My plan is to swap the rear case with one from another iPhone 6 that is still under warranty and have the phone replaced. Now, if you think there is something fraudulent going on, you right! There is a person who just want the phone replaced. Then there is a company that sold her this POS and then lied about it and refuses to fix it.
