Replacing the LCD on the iPhone 7 plus and the screen comes on but no touch I’d or respond to the home button. I’ve disassembled it a few times and put it back together but i cant find the fault. Any one have any ideas?
Check the contact when flipping the screen back down, those two contact circles need to make a proper connection once the screen is put back on, there are two leaf clips that can be damaged opening the phone. Hope this was helpful .
The Home button will not work when you replace a new screen even you use the old Home button, the iPhone 7 is different from other iPhones.
