iPhone 6s fingerprint problems
i recently buyed a dozen of I6s and i6s + screens,
and i had a question about the fingerpringt,
i have 3 iphones (2 iphone 6s & 1 iphone 6s+)
they all have the same problem , i replaced all the iphone screens and1 of the 3 works.
i tried the button on all the screens that i have an none of them works i try to use the one that works on the screens and also they do not work, i replaced the button back to the one that worked and then it did not work anymore, i keep on trying and suddenly i manage to make it get back to work aggain so i leave that phone alone, but is there a way that i might have damaged it :s or an component. or are the screens all faulty?
because i never had so much trouble then with the iphone 6s its realy abnormal.
