Mr screen was broken and I replaced it. My Touch ID stopped working after I replaced the Screen. Can anybody help me on how to solve this problem.
Hello, During the replacement of your screen on the iPhone 5s, 6 and 6+ you MUST transfer over the original home button. There are coded values between the Ax processor and the Touch ID that MUST match for the Touch ID to functional properly. On the iPhone 6 and iPhone 6+ there is the long “Touch ID extension flex cable” that runs down the back of the heat shield on the LCD assembly. This can become damaged and doing so may cause the Touch ID to stop working. There are data buses and the physical button contact on that flex cable. I’m sure you get my point now, the flex cable is a cheap fix, simply buy a new one from eBay, ifxit, or amazon and replace. Thanks, Nate
