The listing needs to make clear that this fingerprint sensor will discontinue the fingerprint reader functionality of the S5 G900F. Until it does, it's listing and selling an item falsely.
Added to that, mine came manufactured with the button skewed on the locator board (even like the listing images); it doesn't sit well into the phone when reassembling and nor does a stressed ribbon cable.
I've troubleshot all aspects and used all tricks on the software side to get the fingerprint scanner working, but the fingerprint reader service now crashes whenever it's called, which could bring showstopper issues down the line in apps with scanner functionality that call it.
On the plus side it's a button that clicks, and it's the correct colour.
