Another Touch ID not working questionI bought an iPhone 7 with a screen that had a single crack in it. Tested it and everything worked fine including touch id....
Answer to "Another Touch ID not working question"Got the new screen and the culprit was the flex cable on the screen itself. Changed the screen and now Touch id is working .
Answer to "iPhone 6 home button won't work but Touch ID does"I had the same problem, and the flex cable was the culprit. I didn't think the OEM cable got damaged, but picked up a new one, it didn't work, also tried a new home button, still not working. I then tried another flex cable and was extremly carefull installing it, when I screwed the backplate back on I was carefull not to put any preassure on the cable and this time it worked :). Seems like these flex cables are extremly fragile.
