We now have a better idea about what has been causing Touch ID accuracy issues for some users, as well as what improvements were made to the system in last week's iOS 7.1.1 update. Many Touch ID errors appear to stem from bad setup scans, which prevented Touch ID from improving over time for several users. It appears that iOS 7.1.1 solves this issue, as well as reducing the number of calculations the iPhone has to make, speeding up the unlocking process, according to Reddit user iOSecure:
With iOS 7.1.1 Apple now takes multiple scans of each position you place finger at setup instead of a single one and uses algorithms to predict potential errors that could arise in the future. Touch ID was supposed to gradually improve accuracy with every scan but the problem was if you didn't scan well on setup it would ruin your experience until you re-setup your finger. iOS 7.1.1 not only removes that problem and increases accuracy but also greatly reduces the calculations your iPhone 5S had to make while unlocking the device which means you should get a much faster unlock time.
Is Touch ID working better for you since you updated to iOS 7.1.1? Let us know below in the comments.
