A few weeks ago Dr. Drang wrote about the deteriorating accuracy of TouchID on his iPhone 5s. I wasn't experiencing the problem but, because I am thick, I decided to retrain TouchID on my phone anyway. Now, touch ID is slow for me and misses much more often than it ever did before. Thankfully Serenity Caldwell just published an article for Macworld with some tips. I'm going to retrain again today and hopefully put this all behind me.
