Answer to "How do you fix the iPhone 7 ghost touch issue after screen replacement"I myself read many answers to fix my phone ( iPhone 6). It use to “ghost type” and freeze. I read in some forum to twist the phone. Which gave me the idea that screen is not in straight line. I removed the screen guard and cleaned the iPhone screen. It did not work. Finally, I removed the hard case that it had to protect back. All the problems were immediately gone. It seems the hard case itself got twisted by a previous drop which was further twisting iPhone screen.
