After a few days, it would more often than not fail on the first attempt. Several times per day, it would fail five times in a row, so that I would have to type my passcode.<\/p>\n<p>I tried cleaning the Touch ID sensor. I tried retraining it many times, using different fingers, different parts of the fingers, multiple copies of the same finger, etc. Nothing seemed to help.<\/p>\n<p>Because you <a href=\"http:\/\/mjtsai.com\/blog\/2013\/10\/10\/touch-id-and-require-passcode-immediately\/\">can&rsquo;t have a passcode delay when using Touch ID<\/a>, this made Touch ID much more trouble than it was worth, so I turned it off for several weeks. The iPhone was immediately more pleasant to use.<\/p>\n<p>A couple weeks after updating to iOS 7.0.4, I decided to give Touch ID another try. I trained it with four versions of my right thumb. I had tried this before, but this time it worked. Over the last nine days, I have unlocked my phone probably at least 200 times, and Touch ID only failed twice. The two times were consecutive. I had just entered a building after being outside without gloves, and so my fingers were cold; I&rsquo;m not sure whether that has anything to do with it.<\/p>\n<p>I&rsquo;m not sure whether the improvement is due iOS 7.0.4 or happening on a <a href=\"http:\/\/nslog.com\/2013\/12\/13\/touchid_accuracy_decay\">more effective training<\/a>. In any case, 99% accuracy makes a world of difference. Before, I had dreaded unlocking my phone because I expected it to fail, and fail, and fail. Now I just assume that it will work. And it&rsquo;s worked through dry skin, sweaty hands, slightly dirty hands, lotioned hands, etc. It even worked, sideways, when my phone was in a car mount, and swiping and typing the passcode would have been awkward.<\/p>","protected":false},"excerpt":{"rendered":"<p>For the first six weeks or so, my experience was that Touch ID worked pretty well for a day or two, and then the accuracy rapidly declined.
