'''BEWARE IPHONE 8 SCREENS ON EBAY!'''
I bought from two different sellers. One from China and on in the US. (Of course, I sorted by lowest price). When i installed the screens, the phone was boot looping over and over. Couldn't figure out why, until it occurred to me that the screens looked exactly like iPhone 7 screens. So I put the old cracked screen back on the iPhone 8 and it worked fine. Then, I tested the screens with an iPhone 7 and... ALL OF THEM WORKED.
The US seller gave me a shipping label and apologized, but the Chinese seller argued with me and insisted that I broke the screens or was doing it wrong. I have a pending eBay case... He did not get good feedback.
