iPhone Home Button Ribbon Cable Replacement?
In an attempt to replace my iPhone 7 battery, I tore what I have gathered to be the ribbon cable responsible for touch ID (when iPhone is open like a book, the bottom cable closest to the home-button-end of the phone that falls flesh with the circuit board on the front half of the phone). I understand that in order to replace this cable the entire backlight needs to be replaced.
I read on an older thread that once the backlight is replaced, the home button needs to be calibrated using equipment that only Apple has access to? Is this true? I would be using the original physical home button of the phone, just replacing the backlight. And even with an entire backlight replacement there is still a 50/50 chance that the home button won’t work? Just want to clarify before I spend the money and decide if I’d be better off saving up for a new phone.
Es esta una buena pregunta?
