Would it be tied to the WatchOS beta? Since it’s running on the phone now, I would imagine it would update with iOS.
Got a tip for us?

Apple Releases Fourth Public Betas of iOS 26 and More

I’ve had several bugs on my 16P, the FindMy app will go transparent with no shading behind friends/items/etc, I’ve received messages from contacts that says it’s from an “unknown sender,” and I’ve had the messaging text be really small (almost like the small font effect) with no formatting on the text, just to name a few.
It still collects the data on the watch using the Blood Oxygen app, the phone just processes it and displays results. If you open the app on the watch in PB3 it stills says "The Blood Oxygen app is no longer available."
So, interestingly I found the cause...or a workaround at least. If I turn off Call On Other Devices in the Cellular settings my notifications work fine.
If it matters I had this enabled for both my Mac and my iPad, both of which are also on the Public Betas and my service is with Visible.
I really like the iPadOS changes and the only bug I’ve seen has been the blank home screen issue others reported. However iOS 26 had been fine until dev beta 5. After that CarPlay no longer connects wired or wireless and I had restore to iOS 18 to get it working again ☹️
Apple today released the fourth public betas of iOS 26, iPadOS 26, and macOS 26, allowing the public to test the updates ahead of their September launch. The fourth public betas come a week after the third public betas, and the updates correspond with the seventh developer betas that were released earlier today.
Public beta testers that have registered on Apple's website can download the latest iOS 26, iPadOS 26, and macOS 26 public betas by opening the Settings or System Settings app, going to the General section, tapping on Software Update, and choosing the iOS 26, iPadOS 26, or macOS 26 Public Beta options.
iOS 26 and iPadOS 26 feature Apple's Liquid Glass design, with a visual aesthetic that focuses on transparency. Icons, menu buttons, navigation bars, and more reflect and refract light with subtle animations. There are pop-out menus in some areas, tab bars shrink down, and everything has a more rounded look.
There are new Apple Intelligence features like Visual Intelligence for screenshots, updated order tracking in the Wallet app, new features in Reminders, and Live Translation for the Messages, Phone, and FaceTime apps. Image Playground has ChatGPT style options, and Genmoji supports mixing two or more emoji characters to make something new.
2D photos have a more 3D look with a Spatial Scene feature, and Safari has updated navigation. In the Phone app, there are new Call Screening and Hold Assist features that will save you time, while the Messages app supports customizable backgrounds and polls. Apple Music has a DJ-like AutoMix feature, CarPlay has an overhauled interface, there's a new Apple Games app, and Preview has come to the iPhone for the first time.
macOS Tahoe has the same Liquid Glass design as iOS 26, and it extends to app icons, folders, the Dock, in-app navigation, menus, the Control Center, and the Menu Bar. The Control Center and the Menu Bar are customizable, and you're also able to customize folders, app icons, and widgets.
Safari has an updated tab design and a redesigned sidebar, and Apple has brought the Phone app to the Mac for making phone calls through Wi-Fi Calling. The Phone app supports the new Call Screening and Hold Assist features.
Spotlight has been overhauled with improved search and the ability to execute hundreds of actions without opening up an app. There's a new Games app with a Game Overlay feature, and developers have access to Metal 4.
More on what's new can be found in our iOS 26, iPadOS 26, and macOS Tahoe roundups.

OSX Reloaded. Like candy? Hmmm.
Animations are smooth now, feels like final release really now.
Was hoping for Apple Watch update too as I can’t see any icons in control center, but looks like that’s not ready yet.
Apart from iphone 15 pro max overheating a bit while using the camera mainly, I’m impressed with the lack of major bugs in these betas.

After public beta 3, I installed this version 4 on my iPhone 11 Pro: it's a matter of taste, but I find iOS "modernized" with this 26. While the user environment remains essentially the same (which is useful for many users, in order to maintain a familiar profile in use), I find the Liquid Glass graphical aspect interesting.
The animations seem essentially as fluid as in PB3, perhaps slightly less snappy, but more consistent and harmonious when opening the app. Menus and transitions between sessions are sufficiently fluid and fast, much faster than in iOS 18.6.1. Perhaps the Control Center's transparency is less noticeable on PB4, creating a more opaque background than in PB3... but I'm not entirely sure!
I repeat, on an iPhone with a 60Hz display, it already seems to perform well, even without the increased fluidity associated with 120Hz!
Obviously, being on a such older iPhone, I don't have the opportunity to test the many AI features. Ultimately, this PB4 seems better than the PB3, even more stable, although I can't yet judge battery life (with a 99% health status, non-Apple aftermarket battery). Honestly, I hope for a quick release of the Release Candidate (at this point, since PB4 has the final code with the letter "a," we could be very close to the RC!) and the final version.
I should point out that I'm a bit older (59 years), and therefore tend to be less demanding. While I'm still fairly knowledgeable about computers, I've been using MacOS well for 30 years, and I'm not much of a actual boomer!
Have other users installed this on an iPhone 11 Pro?
Edit: some sporadic overheating during the use of Chrome or WhatsApp..is not usual.
Battery last a Little faster than PB3.

I've just found that iOS 18.6.1 will no longer play some mp3 files in the Music app, specifically MPEG-1, Layer 2. These have worked since iPhone 1.0. Is this resolved in iOS 26?
I'll update with some personal experience: on the iPhone 11 Pro, the system runs fairly smoothly (better than on iOS 18.6.1), but I find a few things annoying:
1) Some sporadic overheating, apparently unrelated to any particular use. I believe this also drains the battery further;
2) If you use dark mode as a theme, some apps aren't easy to read. For example, if you use FaceTime in dark mode, in the call history you can't see the circle you need to select at the top of the contact card to delete that call. If you switch from dark to light, that circle appears and you can delete it. I also noticed this strange behavior when changing the payment method in the Apple Store or iCloud (I switched from credit card to PayPal). When in dark mode, you can't read the information boxes (they appear practically black). Switching to light mode, everything is readable perfectly;
3) Very annoyingly, the "system data" in Settings/General/iPhone Space is excessive (over 9 GB...in iOS 18.6.1 it was less than 4 GB) and we're talking about an iPhone without artificial intelligence. I believe this has something to do with the "beta" nature of this release and the update method, rather than just the spotlight indexing that happens with each new update (and the sporadic overheating could be that occurring symptom). Perhaps it would be better to erase and reinstall from an iCloud backup or from a Mac (assuming it doesn't also recover those excessive GB). But it makes sense, if necessary, to do it with the final version of iOS 26.
The rest is as usual, boring when it's boring, interesting when it's interesting: it depends on what we do with the iPhone!

So it works? Back on the 8th of this month I tried to install the PB on my M4 Pro and while it looked like it installed fine, anytime I would try to open an app from the dock, it would respring and generate a crash report. Fed up I decided to restore from the backup I made earlier that day and that was where the fun began. 8hrs later and with the help of a 3rd party app, I was able to restore it.
