After replacing my iPhone 7 screen, if you hold in hand and use it, it works fine—but if you are not touching your other hand to the phone body, then digitizer doesn’t work. It works when plugged in for charging though. It seems like some kind of grounding issue. I have tried 3 new screens and same issue. Please advise. Thanks!
I’ve had a similar problem like this before. I was able to fix the problem by putting kepton tape on the board. This worked for me. Good luck
