The screen on my 6S is cracked and I have a spare 6S that doesn't work anymore due to water damage. Instead of buying a new screen would I be able to use the broken one as a donor screen? or should I replace it? And I remember reading something about the home button being unique to each phone because of the fingerprint scanner. Would I just need to switch the fingerprint home button out and it will be fine to use as a replacement screen? I googled and found that TCAWireless is the place in Hawaii which solves screen replacement issues. But before that I just want to ask that is it possible?
