iPhone 7 Touch ID doesn't work
I've replaced an iPhone 7 Display (refurbished, original LCD), but after I powered the iPhone on, I couldn't add a fingerprint anymore.
The fault indication (that Touch ID has a failure) does not appear in the homescreen, but appears if I try to add a new fingerprint.
Homebutton (still the original one) and 3D are working without any problems.
Thanks in advance for your help.
Is this a good question?
