Apple released iOS 7.1.1 last week, and you'd be well advised to download it to your devices. You can do so over the air by going to Settings > General > Software Update. Or you can connect your device to your computer and do the update via the iTunes software. The update fixes important security issues as well as bugs. Most importantly for iPhone 5s owners, it reportedly helps to make Touch ID faster and more accurate. According to a detailed explanation on Cult of Mac, accuracy would decay over time. Quoting a Reddit user, the post explains how the update improves Touch ID: "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." In the past, if you didn't get a good scan during setup, it would later cause problems. The increased accuracy of the update results in a faster response because the phone needs to make fewer calculations while unlocking the phone.
