As expected, Apple has followed the release of iOS 15.3 with the beta-testing releases for iOS 15.4 (and associated operating systems like iPadOS, watchOS, and tvOS). We’re still waiting on a couple of significant iOS 15 features that are supposed to be released this spring, and this beta finally brings the first look at Universal Control (together with the macOS 12.3 beta). It’s hoped that, over the course of the beta testing releases, these features will show up in iOS 15.4, but Apple may still delay them further.
iOS 15.4: New features
Universal Control
The iPadOS 15.4 beta finally brings Universal Control, which was supposed to release last fall but was delayed until spring 2022. The feature, which lets you drag and drop files between the iPad and Mac (or different Macs) as well as share keyboard and mouse wirelessly between them, can be found in the AirPlay & Handoff tab in the General Settings. There, you’ll see a new Cursor and Keyboard (Beta) option.
Face ID with Mask
Better late than never, right? While iOS 14.5 let you unlock your iPhone with your Apple Watch when Face ID doesn’t work, that’s not a lot of use for those who don’t have a watch but are trying to reduce the spread of a deadly pandemic by wearing a mask in public spaces.
Inside the Face ID & Passcode settings you’ll find a new toggle to Use Face ID with a Mask. When turned on, Face ID will “use the unique features around the eye area to authenticate” rather than full facial recognition. There’s also a new “Add Glasses” setting so the system can properly identify your facial features. Apple warns that Face ID is more accurate with the settings turned off.
Emojis
There are several dozen new emoji as part of the Unicode Consortium’s Emoji 14 release. They include melting face, saluting face, biting lip, jar, beans, x-ray, bubbles, and more.
DualSense adaptive triggers
This release enables developers to support the adaptive triggers function of the PlayStation 5 DualSense controller.
iCloud Keychain notes
You can add notes to a password entry in Keychain. Head to Settings > Passwords to see your Keychain entries.
Apple Card Widget
There’s a new Apple Card widget that can be added to your home screen or Today view. It shows your current balance and spending activity.
Vaccination records in the EU
The Health app now supports the EU Digital COVID Certificate format, so you can add your vaccine record to the Health and Wallet apps in supported regions.
iOS 15.4: How to get it
If you’re interested in beta-testing iOS 15.4 (or iPadOS 15.4), you should do so on a device that is not your primary everyday iPhone or iPad.
Registered developers can go to developer.apple.com/download using the device upon which they wish to run the beta. From there, you can download a developer beta profile. Head to Settings > General > VPN & Device Management to enable the beta profile. Then your iPhone or iPad will restart, and you can go to Settings > General > Software Update to download the latest version.
To participate in the public beta test (which usually gets beta builds between a few hours and a day after the developers do), head to beta.apple.com using the device upon which you wish to run the beta. From there, you can download a developer beta profile. Head to Settings > General > VPN & Device Management to enable the beta profile. Then your iPhone or iPad will restart, and you can go to Settings > General > Software Update to download the latest version.
