OK I installed iOS 26 on my phone. I’ve concluded that the Liquid Glass idea is fundamentally impossible to get right, because the aesthetic ambitions are directly opposed to the functionality of the interface.
You can’t make elevated UI elements nearly transparent, while also keeping them readable on top of background content that can have any combination of colors.
The only way to solve this is to not do this—the UI just has to be more opaque.
There are always those awkward situations where the ambient light is diffuse and you can actually read stuff on those screens without light reflexes and mirror effects.
The Liquid Glass comes to the rescue and makes sure you can never easily read a thing.
That's innovation.
