iOS 26 beta 4 is out now for iPhones on the developer beta release cycle. Below we’re collecting all of the iOS 26 beta 4 changes compared to the previous version.
iOS 26 beta 4 changes
First up, we know there are a few design changes coming in macOS Tahoe 26. This includes a redesigned Music app that now reflects the look of the Podcasts app. Specifically, the sidebar now reacts to content beneath it rather than being a separate part of the window.

Both of these changes appeared on Monday when Apple accidentally sent the macOS Tahoe 26 public beta (still unreleased) through the wrong beta channel. macOS Tahoe 26 developer beta 4 first posted on Apple’s developer portal before hitting the OTA update method.
As for iOS 26 and iPadOS 26, early findings show that Liquid Glass is back in tool bars where it was more frosted in beta 3.
Beta 4
Camera app now has an informational splash screen about the redesign:
Phone now has updated settings around silencing unknown callers and managing the new call screening feature.

Apple has also added a Dynamic color option for the iOS 26/iPadOS 26 wallpaper in beta 4. The previous beta introduced new color options.
After pausing News & Entertainment notification summaries, Apple is re-enabling the feature in iOS 26 as part of beta 4. More information here.
