Apple has introduced its Liquid Glass design in iOS 26, allowing users to make their iPhone homescreen icons completely clear. The public beta offers this feature, which can be applied by following these steps:
To start, long-press anywhere on the wallpaper background to access the Customize option. Tap it and select Clear from the pop-up menu at the bottom of the screen. This will immediately apply the Liquid Glass design to your icons, allowing you to see through them to your wallpaper.
The process is straightforward, just like previous icon customization options. Simply follow the same steps to try a different look or return to the original setting. With iOS 26’s Liquid Glass design, users can enjoy a unique and futuristic aesthetic on their iPhone homescreen.
