Repair guy swapped device's screen with another device's, mistake?
Long story short:
I took my iPhone 6 to a repair guy then when I had it back I noticed the screen was not the same screen the device got in with.
He said maybe one of their guys put it in the device by mistake
Now, my screen originally had two small cracks, that is how I noticed. Can he actually swap two screens without knowing? As in swapping mine with another device's by mistake?
Touch ID works fine, isn't it the home button that stores it? And it won't work if it was another device's home button? So he had to disassemble the screen to swap it (by mistake)?
Please replay urgently.
Update 1: I have noticed that the earpiece is different than mine (it is louder, mine was weak due to a drop). And home button is noticeably wigglier.
Is this a good question?
