You guys are smart with the details of what will and won't work. Have a question, Had an iphone 6s where i replaced the screen and transferred over the original touch id, home button as I know you can't use a new one. I've done this many times, but this time the touch id won't work after put back together. It doesn't give any error at all. Just when you try to add new finger print, it acts like you don't have your finger on the home button... No errors. It just won't prompt you to scan your finger and can't get it to work. Any ideas?
