Hello, i have fixed somewhere around 100 iphones and have replaced, and restored just about every piece to an iphone. Just recently, the past 2 iphones i have fixed the screens on have had problems. After the install, the LCD seems to be sensitive to touch just like a computer monitor or screen reacts if you touch on it. i have no idea what is causing this as i have disassembled the phone and re assembled it multiple times. I need some advice. i have never had this problem before. i know its possible that the screens can be defective but i didnt think that was the case because it has happened twice in a row now. Please help!
