It's fair to say that Liquid Glass was rather controversial following its debut at WWDC 2025. It's no surprise that such a drastic change caused loyal iPhone users to complain; the same thing happened when iOS 7 made similarly drastic changes back in 2013. But this didn't change the fact that the backlash was so severe that Apple has made a point to tweak Liquid Glass in iOS 27.
The effect hasn't been removed, so any diehard Liquid Glass haters are going to be disappointed. But Apple has made some changes that could prove beneficial to those of you with valid criticisms about Liquid Glass and how the transparency effects actually work. Not only is there a new slider to control how the transparency effects work, but Apple also claims it has adjusted how Liquid Glass elements look on screen.
