Apple today seeded the fourth betas of upcoming iOS 15.4 and iPadOS 15.4 updates to developers for testing purposes, with the new software coming one week after Apple seeded the third betas of iOS 15.4 and iPadOS 15.4.
Developers can download iOS 15.4 and iPadOS 15.4 through the Apple Developer Center or over the air after the proper profile has been installed on an iPhone or iPad.
iOS and iPadOS 15.4 introduce some of the most significant changes we’ve seen in an update since iOS 15 launched. On the iPhone 12 and 13 models, there’s now an option to use Face ID while wearing a mask with no Apple Watch required for authentication. It works just like Face ID, but it scans the area around your eyes when you’re wearing a mask.
