Apple may be planning a subtle but meaningful tweak to its interface with iOS 27. According to Bloomberg’s Mark Gurman, the latest internal build of iOS 27 does not show dramatic Liquid Glass design changes. However, Apple is testing a system-wide setting that could allow users to fine-tune how the interface appears.
Right now, iOS 26.1 offers two liquid glass styles: “Clear” and “Tinted.” The Tinted option increases the opacity of interface elements. It gives buttons and panels a heavier appearance. Even so, users cannot fully control the transparency level across the system.
Apple took a small step forward with iOS 26.2. That update introduced a slider to adjust Liquid Glass opacity. However, the slider only works on the Lock Screen clock. Users can fine-tune the clock’s transparency, but the rest of the interface stays unchanged.
With iOS 27, that limitation could disappear. Gurman reports that Apple may expand the opacity slider to cover the entire operating system. If that happens, users would gain deeper control over how menus, widgets, and other elements appear.
Apple originally aimed to launch a system-wide Liquid Glass slider in iOS 26. However, engineers ran into technical issues while extending the feature across the full system. As a result, the company limited the slider to the Lock Screen clock.
Now, Apple is revisiting the idea. “Apple is trying again now for iOS 27,” Gurman wrote in a social media post, referring to the system-wide Liquid Glass slider. He added, “TBD if it lands.”
For now, the feature remains under development. Apple has not confirmed any changes publicly. iOS 27 beta testing is expected to begin in June, followed by a full release in September.
