Touch ID works but home button doesn't
recently i changed an iphone 7 screen with a new one. The problem with the new screen is that the touch ID is working but the home button is not. When i "press" the button doesnt do anything. I thought that the flex on the screen it could be faulty. I tried with different screen but the problem stills there. So i decided to put everything back on the old screen which is the original screen. The problem still the same. Does anyone has any idea why this happend? It is very weird. The home button flex is not damaged, i checked it already with microscope. Before of the first changing of the screen the button was working fine.
Thanks in advance.
