With Apple announcing its Mac Studio, the iPhone SE 3, the Studio Display, and more at its March 2022 event, the release for iOS 15.4 has followed a week after, available for your iPhone SE, iPhone 6S, and above.
iOS 15 was released in September 2021, and it brought SharePlay, widgets to iPadOS, Focus modes, and more, all focusing on a theme of productivity.
But Apple has been full steam ahead with .1 updates since then, as 15.1, 15.2, and 15.3 have all brought bug fixes and refinements to your iPhone and iPad.
With this in mind, here are five features that you can get acquainted with as iOS 15.4 downloads to your device.
1. Face ID with a mask
While Apple introduced a feature that would allow your Apple Watch to authenticate you by unlocking your phone, it wasn't helpful to those who didn't own a watch.
With iOS 15.4, you can enable an additional feature where you will be asked to scan your face while wearing a mask. The Face ID hardware will then recognize your eyes and facial features to unlock your phone instead.
2. Universal Control with iPadOS 15.4
This is something that was announced at WWDC in 2021, Apple's yearly developer conference, but it was delayed from the latter half of 2021 to the release of iPadOS 15.4.
As long as you have a certain iPad model and a Mac running macOS 12.3 Monterey, you can use your mouse cursor across both devices, so you can drag and drop your content seamlessly.
If you're struggling to set Universal Control up, we've got a guide to help out with that.
3. New Emoji
A new update wouldn't be the same without new emoji, and this time there's a bunch you can use.
From a salute to different genders being pregnant, alongside many new hand gestures, there's plenty to choose from for your WhatsApp and Twitter messages.
4. Better anti-stalking measures for AirTag
When you set up a new AirTag in iOS 15.4, you will be greeted with a pop-up explaining that it's a crime to use it to track people, making users aware of its misuses across the world so far.
There's also better ways to manage its Notifications through the Find My app, so you can configure when the time-tracking alerts will arrive, alongside deciding whether to deliver all of its notifications right away or at a certain time of day.
5. Notes in iCloud Keychain
You've been able to save and sync your passwords in iCloud since 2019 with the release of iOS 13. But 15.4 allows you to add notes to your custom iCloud passwords through iCloud Keychain.
While it sounds like a small feature, it's significant due to other password apps having this for a number of years, and the ease of adding some extra reminders in these sections can help, especially if you have multiple accounts for the same site.
