Apple Introduce Second Public Betas of iOS 15.4 and iPadOS 15.4
A week after Apple released the first public beta of iOS 15.4 and iPadOS 15.4 upgrades, Apple has released the second public betas.

Universal Control, Face ID With Mask Support and Many More launch with iOS 15.4, iPad Os 15.4
A week after Apple released the first public beta of iOS 15.4 and iPadOS 15.4 upgrades, Apple has released the second public betas.
After installing the correct profile from Apple’s public beta testing page, iOS and iPadOS 15.4 may be downloaded over the air.
Both iPad OS 15.4 and iOS 15.4 have received significant improvements. Face ID unlocks your iPhone even if you’re wearing a mask in iOS 15.4 and iPadOS 15.4 adds Universal Control. When coupled with a Mac running macOS Monterey 12.3, Universal Operate can be used to control numerous Macs and iPads with a single mouse and keyboard. MacOS Monterey 12.3 is required for Universal Control, however, it is not yet available for public beta testing.
As of the second beta, Apple Pay, contactless credit and debit cards, and other digital wallets may be accepted on NFC-compatible iPhones through the “Tap to Pay on iPhone” functionality. This eliminates the need for any extra hardware.
In the iOS 15.4 beta, the code for tap-to-pay on the iPhone is included, but third-party suppliers must add support before it can be used. The new “PaymentReceived” sound file and visuals that show off the Tap to Pay interface are not accessible to the end-user.
Meanwhile, according to reports, digital IDs and driver’s licences may be coming to iOS 15.4 soon. There isn’t a tonne of proof supporting this at the present moment, although there was a mention of the functionality in the PassKit code in beta 2. “Find out when your driver’s licence or state ID is available to use and receive vital information regarding your ID,” it says.
Additionally, the betas provide a new Emoji 14, an Apple Card widget, an iPad keyboard brightness Control Centre option, support for setting up a custom email domain on the device, and much more, in addition to the features already there.
