Ever since i bought my 5S, i have never experienced this before.Just curios and wonna know why?Im an addictive user of the touch ID passcode.i have setup both my right and left thumb and been using it ever since i bought my 5S works just great until today this weird thing happened.My phone automatically restarted and just my left thumb works.Now my phone keeps asking me to try again whenever i use the right thumb. Wonna know if this has ever happened to anyone before or is there something wrong with my right thumb or wait.So disgusting i think
