Hello, I have got question for ifixit community! I had replaced a display on iPhone 7 plus for my customer. Everything works fine, but home button not. Touch Id works properly but home button clicks only on finger on. For example; I can’t make double-tap for one hand control, because only on touch it clicks. Had anyone this problem? Some reasons? Thank you, Victor
Readjust the screw right underneath the button, careful not to make it too loose or the button may leak water. On a second thought, maybe you are not aiming for water resistance anyway, so just normal tightness and not too tight to break it, not too loose so it may come off and end you up with a dead forever button.
Hi Victor I have exactly the same problem I am going to approach the central screw tension in the underside of the Touch I/D sensor securing plate as a first step. Costadelsol Update (12/03/2017) Hi There does not seem to be a definite answer to this problem I finished up dismantling the Home button on the clients phone and re-assembling it extremely carefully, to my amazement the home button took a harder press for activation, the over sensitivity problem had gone so I an still in a quandary why the situation occurred in the first instance. Here’s to the next iPhone 7 repair. Costadelsol
Try below steps.. Choose the click that’s right for you. On iPhone 7 and iPhone 7 Plus, go to Settings > General > Home Button, then choose a click. Change 3D Touch sensitivity. Go to Settings > General > Accessibility > 3D Touch, then set 3D Touch sensitivity to Light, Medium, or Firm. let me know if this helps you..
I think the small component that is suspect is that silver rectangle chip on the home button itself. It is held onto the flex with BGA solder balls which consists of a grid of solder balls (5x5) Some of those balls can become loose due to flexing of the ribbon cable right under that chip. That chip is called the Turtle IC. It has quite some underfill around that chip so most experienced micro-solderers have fixtures to hold them firmly in place to remove the underfill and fix the connections under the chip.
sorry to tell you during replacing lcd you have damaged home button ic from right side of the corner if you have microscope please check and replace it with original ic it will definitely work kind regard
I had this problem after taking my phone into the shower with me. I’m not sure if it was the water that caused it though but I was able to eventually fix it. Suspecting that the back plate from the sensor was causing the issue, I used a suction cup and pulled the bottom screen up, without pulling the screen off. When I turned my phone back on afterwards the home button worked normally. Hope this helps.
I have same error too,It’s that work back??
Hi, I got the same issue and I tried to clean the HB from outside with contact cleaning agent and then heated it up for a few seconds. Mine works fine now.

I found the same problem in my iphone 7.opened up the screen and found traces of water on HB. the HB is welded to a shield. I think thats the water which makes the sensor sooo fast. Does anyone knows if we can remove that shield and check if the HB is water damaged and remove that water flux from there and make the HB back to life???
The short answer is that the two most common reasons touch on the home button becomes too sensitive are that the cable has ripped, or there is liquid damage to the home button. If the cable is ripped, you can try to “fix” the traces, but they are ridiculously small. If it has water damage, you can modify the resistors. (I wrote a blog post explaining in more about how to fix these issues in more detail. See link below) https://www.macaleginelectronics.com/blo… The cable usually gets ripped when you tighten the screw for the home button flex grounding plate (see image)
I have had this issue with only 2 phones (of probably 100), one I repaired and one I purchased knowing there was a home button issue. The phone I repaired: put a second new screen in and the problem was resolved (which made me confident to buy the second phone) The phone I purchased… Still having issues. I have connected and reconnected the HB and it will either be too sensitive or not sensitive enough. There are most definitely several possible issues with these.
display is not orignal it doesnot has 3d touch use genuine display
