After upgrading to this latest iOS 7.1.1 update, a number of users have reported an instant fix to Touch ID lagging that was being faced earlier. To know in detail about how Apple managed to fix Touch ID issues this easily after months of reports, a reddit user provides some insight.

Fix Touch ID with iOS 7.1.1 update:

You can read the explanation of how Touch ID fingerprint recognition works and how Apple solved the algorithmic accuracy. However, if even after upgrading to iOS 7.1.1, you haven’t noticed improvement, here is how to fix Touch ID with iOS 7.1.1 update:

  • Delete the finger from Settings > General > Touch ID & Passcode.
  • Set up the fingerprint again.

Here is the explanation provided by reddit user:

Touch ID takes a 88×88 500ppi scan of your finger and temporarily sends that data to a secure cache located near the RAM, after the data is vectorized and forwarded to the secure enclave located on the top left of the A7 near the M7 processor it is immediately discarded after processing. The fingerprint scanner uses subdermal ridge flows (inner layer of skin) to prevent loss of accuracy if you were to have micro cuts or debris on your finger.

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.
