My fp sensor has been great, I really love it as a piece of useful technology. Well we just bought a new house and on the evenings and weekends I'm gutting it and redoing everything (I hate watching TV and need something to do). Needless to say my hands are pretty calloused now after doing this for a couple of weeks. Now I can't get my FP to recognize my finger, even after redoing the setup process repeatedly. Sometimes it catches it, but I'd say it fails 90% of the time. Anyone else? Any suggestions? I guess it will go back to normal after I'm doin tearing up my hands, but it is definitely annoying.
