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.

While headline features often dominate discussions, the subtle refinements introduced in iOS 26 beta 4 play an equally important role in enhancing the overall user experience. These improvements include faster app launches, smoother animations, and more seamless navigation, all of which contribute to a more intuitive and efficient operating system.

Looking to download the latest iOS 26 beta 4 via OTA profile update or the IPSW links? Here’s how to install Apple’s latest developer beta on your iPhone.

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.

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.
