Is there a way to turn off Liquid Glass on iOS 26?

Turn on Reduce Motion too (Accessibility > Motion). Doesn't change how it looks, but it kills the wobbly, stretchy animations, and that was half of what bugged me about it.

You can't switch it off completely, but you can tone it down a lot. Settings > Accessibility > Display & Text Size > Reduce Transparency makes the glass panels mostly solid and easier to read. Increase Contrast on the same page helps too. On the newer 26.x updates there's also a Liquid Glass option under Display & Brightness where you can pick a tinted look instead of the clear one, if you don't see it, update first.
