Iphone 7 home button from another phone

[MTsDriveIn]

Hello,

I just replaced my original screen and original home button with another iphone 7 I got. I’d just swap them, but now my home button doesn’t work at all on none of the phones. They’re both original, but I did a search and found that they need to be calibrated or something, but I really can’t find a Way to do it.

Someone who maybe can help me??

thanks in advance! Best Regards,

There’s a Touch ID chip on the motherboard that has to be match to the Touch ID sensor on the home button. If you take a home button assembly from another iPhone you’ll have the problems you’re experiencing. Apple has special equipment to calibrate the Touch ID system which isn’t available to the public.
