Iphone 7 Plus Touch Id Not Working After Battery Replacement. Dont ask what possessed me to use the word wicked but I have a scratch on the screen of my iPhone and its driving me nuts. We need to jump wires on both two layers of wires on the home button cab.

So what have I done. Your finger should cover the Touch ID sensor completely touching the surrounding metal ring. Thanks for taking the time to read this article.

3Take down the home button flex cable. If the replacement screen is not an original Apple screen then the touch id will not work. Yes only Apple can rectify Touch ID. I show how to fix Touch ID not working errors on an iPhone after you replace the screen.
