How to Turn Off Liquid Glass in iOS 27: Apple Publishes a Slider, Not a Switch

There is no off switch for Liquid Glass in iOS 27. The only control Apple has published is a slider in Settings that moves the effect anywhere from ultra-clear to fully tinted, and nothing in Apple’s description of the update removes the design.

The reason this search keeps coming back is that Liquid Glass is not a feature you switch on. It is how the interface is drawn, so Apple treats it as something to personalize rather than something to disable. iOS 27 arrives free on Monday, September 14 for iPhone 11 and later plus iPhone SE (2nd generation and later), and the slider arrives with it.

What the slider actually offers

Apple describes a range rather than a state. One sentence covers the whole feature, and it says the slider personalizes Liquid Glass by adjusting it between two named points.

What Apple does not do is describe either end as an absence. Fully tinted is one end of a slider that Apple presents as a personalization control, not a setting that stops the material being drawn. If you are looking for a toggle that returns iOS to a flat interface, Apple has never published one.

The readability worry behind the search

Most people typing “turn off” are not asking for a design debate. They are saying they cannot read something. Apple’s own framing for iOS 27 answers that with engineering rather than a switch: the company says the material now has “exceptional readability” with more uniform refraction and improved contrast, and that app icons are sharper and more defined.

The same approach runs across the family. Apple’s September announcements list a Liquid Glass tint slider in macOS 27 Golden Gate, where the company also promises “exceptional readability and greater consistency across apps”, and watchOS 27 on Apple Watch Series 12 carries the same design language. This is a systemwide look with a systemwide dial.

Apple’s published accessibility additions for iOS 27 are richer VoiceOver image descriptions, auto-generated subtitles that can be translated, new Magnifier tools, Accessibility Reader and an expanded Voice Control. None of them is described as a Liquid Glass control.

What Apple has not said

  • The exact path to the slider in Settings, or what it is called on screen.
  • What ultra-clear and fully tinted look like, beyond those two words.
  • Whether the setting applies systemwide, per app, or to third-party apps that use Apple’s materials.
  • Whether the tinted end changes battery life or performance in any way.
  • Any support article covering iOS 27-only settings. Apple’s general update guide was last revised in December 2025 and does not mention iOS 27, so any walkthrough published today is a guess at the interface.

iOS 27 ships free on Monday, September 14. Apple has published a date and not a time, so the first reliable look at the slider will come when the update lands. If Liquid Glass is what sent you searching, open Settings on Monday and look for the dial rather than the switch, because Apple has only ever described one of the two. The iPhone 18 Pro ships with iOS 27 already installed on September 18.
