Touch ID not activated after screen replacement
I purchased a iPhone 6s Plus LCD Screen & Digitizer Full Assembly kit from iFixit and after replacing the screen I'm getting a message that says "Unable to activate Touch ID on this Iphone" and I'm unable to use or setup TouchID. I did the following:
1. Installed the new assembly following the step by step directions on this site
2. Swapped the home button from the old display to the new one
3. After connecting the battery and turning the phone on, everything is working perfectly (Display, touch/scrolling, both cameras, home button, microphones, etc) except for the TouchID. I'm also unable to "double tap" the home button to bring the top of the screen down into reach.
I have seen other posts on this site and have attempted to trouble shoot. I have restored the phone to original factory settings, I have done several "hard resets" to the phone and still get the same error message.
I am starting to think that the replacement display that I received from iFixit is faulty because as soon as I connected my original display back into the phone and swapped the home button back, Touch ID was working again, eliminating the thought that it is a bad logic board.
Any other ideas in mind that you guys recommend or should I go back to iFixit to get a replacement screen under the warranty?
Is this a good question?
