Afternoon,
Firstly, can you give me some more detail? I wouldn’t have a clue why something failed if my description is “fingerprint not working”.
Anyways, can you reply to (at least some) of the following questions:
• does the fingerprint thing say “not recognised” or does it not even try?
• have you verified that screen is an original Samsung panel?
•have you checked you didn’t damage the fingerprint cable?
And as I always say, have a search on Google (or your preferred search engine of choice) and see what comes up because 9 Times out of 10, someone has the same issue as you.
