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.

On iPad, iPadOS 15.4 brings the long awaited Universal Control feature. Paired with a Mac running macOS Monterey 12.3, Universal Control allows multiple Macs and iPads to be controlled with a single cursor and keyboard. It's a feature that works seamlessly after installing the updates, and it is simple and intuitive to use.

There are 37 new emojis with the addition of Emoji 14 characters, so you can now use emojis that include melting face, biting lip, heart hands, bubbles, beans, face with diagonal mouth, palm up hand, eggs, troll, low battery, coral, lotus, and more.

The second beta added support for the "Tap to Pay on iPhone" feature that is designed to allow NFC-compatible iPhones to accept payments through Apple Pay, contactless credit and debit cards, and other digital wallets, without requiring additional hardware.


Tap to Pay on iPhone is enabled in the iOS 15.4 beta, but it does require third-party providers to add support, so it is not yet available for use.

There are also signs that Apple may be planning to roll out support for digital IDs and driver's licenses in iOS 15.4. There isn't a ton of evidence for this at the current time, but there was a mention of the feature in the PassKit code in beta 2. "Find out when your driver's license or state ID is ready to use and get important updates about your ID," it reads.

Other new features include full 120Hz ProMotion support for app animations on iPhone 13 Pro models, EU vaccine certificates in the Wallet app, the ability to turn off notifications for Shortcuts automations, keyboard brightness controls in Control Center on the iPad, an Apple Card widget, iCloud Keychain notes, support for adding custom email domains to iCloud Mail right on device, and a SharePlay option in the share sheet.

We have a full list of all of the features introduced in iOS 15.4 and iPadOS 15.4 in our dedicated guide highlighting everything new in the update.

Update: Apple has also made the iOS 15.4 and iPadOS 15.4 betas available for public beta testers.

Not on this beta yet; is anyone seeing a Safari bug where, occasionally, tapping a link actually causes the old page to suddenly reappear, and the history of that tab to vanish?

Like, you'll go

page 1 (tap link to page 2) → page 2 (tap link to page 3) → page 3 appears briefly, then page 2 again

Side note, I wonder what version this would be if Apple still used the older style of version numbering (i.e. a major release every ~3-5 years with point releases in between rather than calling 1 release each year a point release).

To me the silly thing about the new style is that we're just gonna end up with huge numbers and a heap of confusion. Whereas if this was (for example) iOS 3.5.4 then it'd be easier to remember numbers (and note that it's just a random point release of iOS 3).

Same with MacOS (or OS X... or macOS... whatever the hell it is). I'm not 'Murrican so the names are just a blur to me. Which version is Catalina/Big Sur/El Capitan/Monterey, Yosemite, Sierra... HIGH Sierra...etc? No idea. Is Monterey better than Big Sur as a place to visit? (At least with cats you can go from small to big... 'Murrican landmarks? Hrrrrm). I feel like we hung onto MacOS X for too long and now we're just calling little point releases 11... 12...etc. Less names/numbers would be good thanks Apple :D

Reminders did not sync on last weeks betas for me. But everything else depending on iCloud was working fine. Hope this is fixed.

My disk usage with “Other System data” has gone crazy on all my devices with this beta. Such a shame, I’ve never had this problem with any other beta before, and I’ve been beta testing since public betas were released.

not sure what you’re talking about, iOS has *always* gotten a major new version number every year, and several smaller X.X updates throughout the rest of the year.
OS 1.0 launched on June 29, 2007 and went all the way up to 1.1.5.
2.0 launched on July 11, 2008 and went all the way up to 2.2.1
3.0 launched on June 19, 2009 and went all the way up to 3.1.3 for iPhones and 3.2.2 for iPads.
4.0 launched on June 21, 2010 and went all the way up to 4.2.10 for Verizon iPhones and 4.3.5 for everything else.
The only difference nowadays is that you’re more likely to see a version go to X.4 or X.5 because they release changes to the SDK requiring a bump in the second number, and they don’t really do huge 200+ features in one update releases anymore, instead spreading the features throughout the year

I desperately want a digital driver's license so I can ditch my wallet, but my state is so ass-backwards that it will probably be another decade.
Well, as long as it’s taking, they’re certainly giving more states time to get on board.
@macdduke You only use your license for getting on airplanes? That’s all that it will really be good for right now.
That’s all I’ve used mine for recently. I can’t remember the last time I had to show it to someone.

I don't think Illinois has announced any intention to utilize this either. Heck, we didn't even jump on the COVID exposure notifications.

And it takes 6 months to get our conceal carry license. I doubt the digital ID is anywhere on their radar
Yeah you’re probably right! I find it interesting to see stories online about how the governor wants our state to really get out there and appeal to tech companies and bring them in. I’d agree with that. I’d love to see more come here. But you can’t say you want us to be like that…and also not take advantage of some useful products of tech companies! The COVID exposure notifications and digital ID should be pretty easy things to take advantage of. Even Wisconsin has something for the exposure notifications! Every time I cross the state line into Wisconsin, I get a notification saying they have something available for it. As soon as Apple and Google announced it, it was something I thought Illinois would jump in on in a heartbeat! But now, despite the fact that we know this isn’t going away, I’m not so sure the system makes sense anymore. With COVID being everywhere, and so many places announcing they aren’t going to be keeping track like that anymore, it’s an API that I don’t think is going to get any more use than it currently is. Digital ID is another story. If we could get in on that, it’s one less thing I have to carry in my pocket.
