So recent iPhones will complain of a non-genuine screen even if you take the screen from another iPhone (I found out the hard way), because apparently the screen has the serial number programmed into it and the iPhone checks for a serial number mismatch to determine if it’s a “fake.” Does Apple supply the repair stores with the programmers to change the screen serial? Or do you have to just-in-time order the screen once you have the serial number you’ll be repairing?
What this did for me? Four days ago, I dropped my phone (again) and the screen broke (again) and this time when I had the option of choosing a genuine iPhone screen or a Chinese knockoff, I ordered the knockoff.
