change screen then touch ID and 3D Touch can not work
my I7+ was water damage(old one) so I bought a used I7+ (new one)for replace
because the new one had a crack on the screen
so I change my old one's screen to the new one.
after change screen, touch ID(which is old one's touch ID ) didn't work and my new one's system shows touch ID has issue and will not working
then I though it's because I forgot change touch ID either, so I change touch ID from old one to new one (which is pair with the new one's CPU) but same thing still happened.
there has any thing i can do to get my touch ID back to work?
