iPhone 5S Touch ID not working?
so I just bought this iPhone off a local classifieds website yesterday, and everything turned out great all buttons worked and sounds and functions were perfect, all except one thing, my Touch ID fingerprint scanner was not working, I've searched on the internet all day for similar problems, and I've come down to two possible reasons behind it, either the phone was dropped and the home button needed to be replaced and since only the original touch ID works for the original phone that is why it is not working, OR the sensor itself is not working, I've emailed the person I had bought it from as they were very kind I during the process of buying the phone, but as of now they have not gotten back to me. If you have any suggestions or have experienced a similar problem in the past, please I'd like to hear what you did, or how you went about to fix it.
(also as of right now I have not been to an apple or phone specialist in person about the problem)
thanks in advance everyone,
