My daughter’s iPhone 8 suddenly lost functionality on the home button. I ordered a new one from ifixit and replaced it. The new one doesn’t work either. Any ideas what else it could be? Screen seems okay. A couple of times colors seemed inverted but touch works fine. No obvious signs of water damage… hesitant to spend money on a new screen assembly unless it seems extremely likely that’s the culprit. Thoughts?
You would need to rule out your screen. The main reason for a non-functional home button on the 7 and 8 series is a faulty home button flex cable, the one that goes from the screen to the logic board.
