Google's Android 16 update introduces innovative app icon customization features, allowing users to modify app icons with various shapes, styles, and thematic integrations. The QPR2 beta mandates monochrome filters for all applications, ensuring a cohesive aesthetic across the home screen. Users can choose from five distinct icon shapes, addressing feedback on rigid designs. The update also includes forced dark mode and auto-theming for legacy applications, enhancing the overall user experience. Customizable Quick Settings panels and live notifications improve efficiency for power users. Starting October 15, 2025, developers will be required to provide adaptive icons due to new mandatory theming rules. Privacy features, such as protections against SMS one-time password hijacking, are also included.
