Also some people would encounter this situation, after replacing the screen replacement, not only the touch ID failed but also you can’t go back to your menu by pressing the home button and set up your fingerprint. When this happened, first thing you can try is to connect your device to computer and back up your data, then root your iPhone through iTunes, normally, doing this can solve the problem.



3. Another possible reason for this situation could be the broken home button flex cable
