Last week, Apple teased that they would be releasing iOS 15.4 this week, and for those who have been looking forward to the update, you’ll be pleased to learn that it is now available and you can download it and update your iPhone already.
While Apple does tend to release updates from time to time, one of the more exciting features of this particular update is that it allows iPhone users to unlock their devices while wearing a mask using Face ID, which ironically enough was initially designed to be smart enough to detect when someone is wearing a mask and would prevent the phone from unlocking.
This is due to the ongoing pandemic where in many parts of the world, people are still wearing masks either by choice or due to government mandates. By giving users the ability to unlock their devices even when a mask is worn is pretty useful because prior to that, the only way users could unlock their iPhones was either using an Apple Watch or entering a passcode manually.
That being said, keep in mind that this mask unlocking feature is exclusive to the iPhone 12 and later, so even though devices like the iPhone X, iPhone XS, and iPhone 11 series all support Face ID, they will not be able to fully take advantage of this feature.
