    Touchid doesn't recognize your fingerprint after you wash and dry your hands. It takes a while for it to work. Has anyone noticed this?

    Yes, of course it takes a while because your fingerprint isn't clear on your finger, the same as with dirt/oils etc...

    my finger doesn't work a lot of the time, I've made a couple different scans of my finger in different conditions so it will work.

    That's because it's still wet. Either dry more thoroughly or simply manually enter the passcode if you know it's wet, until it's completely dry.

    Aside from wet fingers not registering, I've also noticed that since we're in winter here in the U.S. and the skin on my fingers tends to be much drier than it is any other time of the year, Touch ID often takes several attempts to recognize my fingerprint -- if it's recognized at all. As soon as I push lotion on my hands, Touch ID works almost every single time.

    Re-register the same fingerprint in the winter but don't erase the other one. That way, Touch ID will work year round.

    Works just fine if I dry my hands. If my fingertips aren't dry then I have problems.

    I noticed that it doesnt work even when you dry your hands especially after shower, it takes a few minutes. Its possible that it changes the fingerprint patterns which the touchid sensor uses just enough for it not to recognize.

    Yes, skin can absorb water so it's still not completely dry. You can try registering a second print immediately after showering if it's a recurring problem.

    Maybe I must dry my hands properly? Never had an issue after washing my hands or a couple of minutes after showering :confused:

    Obviously if they are actually wet, I'm sure it won't read it, but I've never tried to use it with wet fingers....

    My touch ID is horrible. Every morning I have to retrain it. It works awesome RIGHT AFTER the learning phase, then gets worse throughout the day.

    It's got to be a software issue...Has anyone noticed this being a problem in the betas?

    Dry or Wet hands affect the scan Sometimes touching powdery foods like nuts etc affect the scan and also dirt etc on the home button makes scanning harder. Be patient. Use cream on your hands if they are dry and keeping your IPhone clean will all help. Nothing is perfect under all conditions.

    They need to put out instructions detailing how to properly keep our hands clean and up to standards for their sensor...

    I wash my hands many times throughout the day. I've tried learning prints in the morning and at night and throughout the day to catch all different conditions.

    Dry your hands better. Even when I get out of the shower and dry my hands, Touch ID works.
