Apple recently released the official iOS and iPadOS 13.5 updates, more than a month after the release of iOS 13.4.1, and one of the most important updates in the new system is the ability for iPhone users to unlock their phones while wearing a mask.
In iOS and iPadOS 13.5, apple has optimized face ID so that when the iPhone detects that a user is wearing a mask, it pops up the password-entry screen instead of repeatedly swiping up.

In contrast, previous attempts to unlock a user's face ID while wearing a mask were cumbersome, with the user usually having to swipe up multiple times to enter a password.In response to the changes, apple said the easier unlocking was in response to the current outbreak.
In addition, the iOS and iPadOS 13.5 systems include the covid-19 contact tracking technology API, which allows health organizations to start developing covid-19 tracking apps. iOS 13.5 speeds up the display of password bars on devices equipped with face ids when a user is wearing a mask, and includes an "exposure notification" API to support the covid-19 contact tracking App from public health authorities.This update also adds options to control the automatic highlighting of video collages during FaceTime group chats and includes bug fixes and other improvements.
