I have got a iPhone 6 plus and the touch screen is not working I I have replaced the screen and the digitiser and still no sign of it working. I have hard reset the phone many times I’m pretty sure its not the touch disease that’s been going on. I have checked the display connectors and no sign of it being broken.
If you tested several screens, touch connection is clean and in good shape, you hard reset it and still not working the only thing left is trying a new Touch IC.
