Apple Support shows how to use two useful features from the iOS 15.4 update (VIDEOS)

If you didn’t update your iPhone to iOS 15.4 yet, this is how it is done. Go to Settings > General > Software Update. Download and then install the latest iOS build. And now, with your phone running on iOS 15.4, you are ready to scan text into the Notes app.
The update also includes a feature that allows you to use Face ID even while wearing a mask. And we know exactly what you’re thinking. “Hey, didn’t Apple already release an update last year that allows you to use Face ID while wearing a mask?
The reason why this feature is so limited has to do with how it works. The FaceTime camera verifies the identity of the user by using a small area of the face around the user’s eyes. Users will have to setup Face ID again, but that shouldn’t be a hardship.
Follow the directions in the video and you should never have to take your mask off to unlock your iPhone again.
