Answer to: iPhone 7 home button not working after screen replacementIt is after market screens, we see this every year with the new iPhones. There is always something manufacturers need to work the kinks out. The 5C had bad touch issues, the 6 had frame lifting issues, 6s with force touch and now with the 7 it's the aftermarket force touch/backlight again. We should be getting answers from suppliers. And iFixit screens do the same thing, I've tried. I've only had a couple screens from different suppliers work. It's like a needle in a haystack right now.
