Recently I had purchased an iPhone 5s from a friend and I decided to fix the phone myself and replace the missing home button. I bought a home button from eBay and amazon and connected the cable but it said that the Touch ID did not work.
This is not my first time fixing a 5s as I own a 5s that I've changed the screen a few times. I've reconnected the cord multiple times and disconnected it but the Touch ID continuously does not work.
I wanted to know how come this issue occurs ? And is there anywhere I can purchase a few home buttons that will work with Touch ID because the ones that I've had, do no simply work.
