I installed the iPhone 7 replacement screen. It performs flawlessly at times and or doesn’t respond or clicks stuff I wasn’t pressing. I touch one contact and it calls someone else. I followed the procedure to the T. Can it just be the screen? About 8 months back I ordered a screen and it did not work. I fixit sent me a new one and it has worked perfectly ever since. Is it possible that the screen it self is faulty or is it operator error?
It does sound like a faulty touch, has happened to me before on a few phones. Try another one and see if that helps
