Liquid Glass - Love It Or Hate It - It's … - Apple Community

According to Apple:

After a software update is installed for iOS, iPadOS, tvOS, watchOS, and visionOS, it cannot be downgraded to the previous version.

What you can do about this:

Open Settings ➢ Accessibility ➢ Display & Text Size, then toggle Reduce Transparency = on.

Also in Settings ➢ Accessibility ➢ Motion, then toggle Reduce Motion = on.

Also in Settings ➢ Display & Brightness ➢ Liquid Glass ➢ Tinted.

In addition, you can provide ⇢ Product Feedback.

If enough requests are made, your feedback might help with future development, like a toggle in the settings.

Good luck! 👋🏼😉

Make sure to update to iOS 26.2 to take advantage of some of the additional options to reduce the Liquid Glass effects.
