IOS 26.4 OFFERS TWO LIQUID GLASS CUSTOMIZATION UPDATES

Summary from the TLDR Design newsletter

iOS 26.4 introduces expanded customization for the Liquid Glass interface with a new “Reduce Bright Effects” setting that minimizes flashing highlights during interactions, alongside an improved “Reduce Motion” feature that more reliably reduces animations for motion-sensitive users. Both options are found in Accessibility settings and continue Apple's incremental approach to UI customization, with rumors suggesting a more advanced slider control may arrive in iOS 27.
