After trading some of the ‘liquid’ in iOS 26 beta 3 for a more ‘frosted’ look, Liquid Glass appears back in full force in beta 4.

Apple has dropped the iOS 26 developer beta 4 and it brings back the "glass" in Liquid Glass along with other major changes.

Apple's iOS 26 development continues apace as dev beta three launches now with several tweaks and updates to Apple's next iteration of its iPhone operating system. Beta three isn't as extensive as iOS 26 beta two, but there are improvements to take note of.

Apple apparently wasn’t satisfied with the Liquid Glass look in beta 2. iOS 26 beta 3 introduces another change, and now the glass isn’t that liquid anymore. The transparency has been reduced even further, giving the overall effect of frosted glass.

The early version in the first developer beta of iOS 26 and the accompanying updates for Apple's other devices still left room for improvement in terms of usability, accessibility, and legibility.

Following the release of iOS 18.6 beta 3, Apple is now making beta 4 available to developers.
