My touch ID doesn't seem very accurate. Maybe 6 out of 10 times it will work. But aside from that... it is weird... I can wipe the button with a micorfiber cloth to a mirror finish, but touch it once and a weird smudge appears... and it is the same smudge... the same shape always. It will seemingly disappear with a wipe with cloth... but always come back with a touch with any finger. Could this be part of the reading issue? Also having random crashes to the Apple logo and Random app crashes. Genius bar? Yay? Nay?
