iOS 27 adds a customizable transparency slider for Liquid Glass elements on iPhone. The setting appears in Settings > Appearance and allows users to adjust the amount of transparency across the system. The feature expands on the Liquid Glass design introduced in iOS 26, which previously offered only Clear or Tinted options. The slider can be positioned at any point along a continuous scale, giving users finer control over the visual effect. Screenshots demonstrate three representative levels: most transparent, default, and most tinted, applied to the App Store, Apple Podcasts, and the lock screen. Apple has indicated that further refinements may occur in upcoming beta releases, but the current implementation is stable.
