Chosen Solution
Hello, I’ve got a weird issue after a screen replacement: my home button doesn’t work even if Touch ID does. I tried to install a replacement home button but the problem wasn’t solved (and obviously the replacement button did not support Touch ID). What could be the problem? I thought about the flex cable that connects the button to the motherboard but if that was the problem even Touch ID should not work. Thank you! Walter
Logically, you would expect the Home button action to work if the Touch ID works. The usual question is normally the opposite situation. In your case, there could still be damage on the extension flex that runs beneath the backlight shield. Just think of it as a highway with multiple lanes. If the Home button lanes are damaged but the others are not, then you would see similar symptoms. You should inspect it closely and test continuity on each pin to be certain. The other possibility is in how you are re-assembling the home button, specifically the backplate (iPhone 6 Plus Home Button Assembly Replacement). this is what the “button” presses against. If it isn;t making solid contact, the the button press will not be noticed.
iPhone 6. Touch ID works, home button doesn’t. I changed the suspected part - flex cable. Problem not solved. Now, I changed the home button, and found that new home button is working, but at the cost of Touch ID. Have anyone incurred a similar problem before. If so, what is the solution.
