    Funny.
    After swimming for an hour, my fingerprint sensor won't recognize me.

    Kind of funny but makes sense.

    I picked some dead skin off my thumb (gross I know) and it didn't know who I was.

    I thought apple said it scans the live layers underneath, not the surface skin?

    If your finger is too wet it will not work. Let it dry for a while and all will be well.

    In the mean time use your passcode.

    It was not wet. Just pruned up.
    Either way, thought it was interesting.

    "Live layers"? A fingerprint comes from the epidermal layer on the surface, not underneath it.

    Its rubbish just like siri was with 4S. Works one day after setup then hit and miss. After having wet hands is well spoken of it not working. Better be a software fix from Apple as a lot of people are frustrated by it. It's off for me, i use the 4 hours passcode.
    Hopefully it won't be another gimmick we pay for but is no good.

    Works every time for me for my right thumb and forefinger. Makes life much simpler as I just press the home button to wake and then leave my thumb/finger there another second to unlock. As I have work email which requires a pass code, it saves a lot of time and is much easier to use. For me, it is the stand-out feature of the 5s and I never want to go back.

    I think the trick is to really move the finger about when you register it so that TouchID can recognise from any angle.

    And? The epidermis makes up the surface of skin as well as 4-5 "live layers" underneath the stratum corneum. It's not all just a bunch of dead cells.

    Trust me, the iPhone fingerprint scanner does NOT scan the dermis.

    I don't see how a software fix could allow it to read a pruned-up finger. I don't have my own 5s yet, but by most accounts the scanner works remarkably well.

    In any case, if you don't like it, why not just unlock your phone with a passcode like you always have? I hope you didn't buy it just for the fingerprint scanner.

    Dont use your willy. It shrinks in cold water and may not work with the scanner.

    You can add another fingerprint when it is pruned up. Then it should work before and after swimming.

    The fingerprint sensor is definitely very temperamental. One thing I have noticed is that if my skin is a little dry, it just will not read my print.

    The problem really is how apple has you set up the fingerprint. They don't tell you to move your finger enough. I actually trained my right thumb as two separate fingers (you can have up to five) and moved my finger every which way. It works very well. Probably not with pruned up fingers, but for those who are complaining that it's no good, give it a try.

    Also A software fix could very well make the sensor better by requiring more reading and allowing more fingerprints to be stored.

    You ever go swimming and have your hands and feet get wrinkled up from the water? You expect the sensor to recognize the print when your finger looks like a prune?

    Why don't you just register the same finger when it's pruned-up in one of the fingerprint slots?

    youre serious right? water seriously disrupts the features of your skin. Technology has limits. Find me other fingerprint scanners on a smartphone that continue to work with a pruned up finger...oh wait lol.

    While we're at it, let me go ahead and complain the touchscreen doesn't work when i wear gloves.

    The fix for this is quite simple:
    Don't go swimming or take a shower;)
