The iPhone 8 Plus home “button” is actually a solid-state sensor, which also includes Touch ID (fingerprint recognition) capability.
Most replacement home buttons won’t work, so check carefully before starting your repair. Your iPhone’s original home button is uniquely paired to the logic board at the factory—and without Apple’s proprietary calibration process, even a genuine replacement home button from another iPhone won’t work. To fix a broken home button, you should install a specially-made, universal-style home button. Note that these replacements only work as a button; Touch ID will not function.
If you are only replacing a broken screen, you can use this guide to carefully remove and transfer your working original home button to a new screen, preserving all functions, including Touch ID.
During this procedure, to avoid accidentally straining or tearing the display cables, it's best to completely detach the display assembly before beginning repairs on the home/Touch ID sensor. But if you are comfortable doing so, you may skip the display assembly section of this guide and go straight to the home/Touch ID sensor section.
What you need
-
-
Power off your iPhone before beginning disassembly.
-
Remove the two 3.5 mm pentalobe screws from the bottom edge of the iPhone.
-
-
-
Use a hairdryer or prepare an iOpener and apply it to the lower edge of the iPhone for about 90 seconds in order to soften up the adhesive underneath.
-
-
-
The next two steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down two steps for an alternate method.
-
Pull the blue handle towards the hinge to disengage opening mode.
-
Position the suction cups just above the home button on the screen—one on the front, and one on the back.
-
Push down on the cups to apply suction to the desired area.
-
-
-
-
Remove four Phillips (JIS) screws securing the lower display cable bracket to the logic board, of the following lengths:
-
Two 1.3 mm screws
-
One 1.4 mm screw
-
One 2.7 mm screw
-
-
-
Use the tip of a spudger or a fingernail to disconnect the large lower display connector by prying it straight up from its socket.
-
-
-
Remove the four Y000 screws securing the bracket over the home/Touch ID sensor:
-
One 1.2 mm screw
-
Three 1.3 mm screws
-
-
-
Flip the display assembly over. Use a hairdryer or prepare an iOpener and apply it to the lower edge of the display for about 90 seconds in order to soften up the adhesive underneath.

If your replacement screen did not come with a front camera and sensor cable, follow these steps to transfer them over.
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
To reassemble your device, follow the above steps in reverse order.
Take your e-waste to an R2 or e-Stewards certified recycler.

aiuto mi son cadute e quindi perso
sensore home/Touch ID Una vite da 1,2 mm Tre viti da 1,3 mm
dove le trovo?
Every time I have tried to transfer the home button from the broken screen to the replacement LCD - the home button has not worked. No tears in the cable. The connector is attached. Screw isn’t too tight. What could I be missing?
ATTENTION: Don’t screw in that one screw over the home button too much, or the button breaks! I just found one proper explanation for it in this YouTube video (https://www.youtube.com/watch?v=rDVnp90a...). Basically, that one screw that goes over the Home button should not be tightened too much, so that the metal plate doesn't bend (which it did for me).
Anybody have the issue where the button works when the phone is in 2 pieces, but when you assemble the screen onto the phone body, the button no longer responds after a restart??
Power on phone while in 2 pieces -> home button is working
Attach screen to phone body -> home button is still working
Restart phone with phone assembled -> home button not responding
Hallo Zusammen
Wird bei diesen Mikroschrauben nur das Gewinde gemessen oder die gesammte Schraube inkl. Schraubenkopf? Ich frage, weil mir die Schrauben des Homebutton weggespickt sind 1.2 und 1.3mm...
Danke
LG
