Apple introduced a major improvement to the Liquid Glass design in iOS 27 by giving users direct control over transparency levels. If you found the original Liquid Glass interface too transparent, too reflective, or difficult to read in certain situations, iOS 27 now lets you customize the effect to match your preferences.
Apple added a dedicated transparency slider, making it easier to choose between a clearer glass look or a more opaque appearance for better readability. This guide covers every available method to adjust Liquid Glass transparency on your iPhone running iOS 27.

Adjust Liquid Glass Transparency Using the New Slider
The easiest and most powerful way to customize the Liquid Glass effect is through Apple’s new system-wide transparency slider.
Unlike previous versions that offered only limited controls, iOS 27 allows you to fine-tune the transparency level across the interface. You can choose anything from a highly transparent look to a much more solid appearance.
- Open Settings on your iPhone.
- Tap Appearance.
- Select Liquid Glass.
- Locate the Transparency Slider.
- Drag the slider left to make the interface more opaque.
- Drag the slider right to increase transparency.
- Preview the changes in real time.
- Exit Settings once you’re satisfied.
The adjustment affects various interface elements, including menus, navigation bars, Control Center, and other Liquid Glass components throughout iOS.
Reduce Transparency Using Accessibility Settings
If you want maximum readability, Apple still provides the traditional Reduce Transparency option.
This setting adds darker backgrounds behind interface elements and significantly reduces translucent effects. It is especially useful for users who have difficulty reading text over colorful wallpapers or busy backgrounds.
- Open Settings.
- Tap Accessibility.
- Select Display & Text Size.
- Turn on Reduce Transparency.
After enabling it, menus, folders, widgets, and Control Center become easier to read because the backgrounds appear more solid.
Increase Contrast for Better Visibility
Some users prefer keeping the Liquid Glass effect while improving text clarity.
The Increase Contrast feature strengthens visual separation between interface elements and backgrounds, making buttons and text easier to identify.
- Open Settings.
- Go to Accessibility.
- Tap Display & Text Size.
- Enable Increase Contrast.
This setting works particularly well when combined with moderate Liquid Glass transparency levels.
Combine Transparency and Accessibility Controls
Many users achieve the best results by combining several settings.
For example:
- Set the Liquid Glass slider to a medium level.
- Enable Increase Contrast.
- Leave Reduce Transparency disabled.
Or, if readability is your top priority:
- Move the transparency slider toward the opaque end.
- Enable Reduce Transparency.
- Turn on Increase Contrast.
This creates one of the clearest interface experiences available in iOS 27.
Adjust Liquid Glass During iPhone Setup
Apple also lets users configure Liquid Glass when setting up an iPhone running iOS 27.
If you’re installing iOS 27 on a new device or resetting your iPhone, you’ll see customization options during the setup process. You can choose your preferred transparency level before reaching the Home Screen.
- Start the iPhone setup process.
- Proceed until the appearance customization screen appears.
- Select your preferred Liquid Glass transparency level.
- Continue with setup.
