└─────────────────────────────────────────────────────────────────┘
1. Hybrid Siri Architecture & Standalone Siri App
Siri has been transformed from a overlay assistant into a dedicated system application. Leveraging Apple’s proprietary Foundation Models alongside integrated access to Google's Gemini models, Siri processes complex contextual prompts, retains long-term conversation history, and accesses personal context across native applications (Mail, Messages, Calendar) to complete multi-step tasks.
2. Liquid Glass Interface Customization
Expanding on the design language introduced in iOS 26, the updated Liquid Glass interface gives users granular control over frosted and clear visual element parameters. System settings now include direct transparency and opacity sliders, customizable blur radii for widgets, and refined iconography.
3. Advanced Visual Intelligence
Users can trigger Visual Intelligence directly via the Camera application or lock screen shortcuts. The feature scans real-world items, architectural landmarks, or text documents to pull contextual data, translate live text, or execute actions through Siri. It also analyzes active screen content on demand.
4. Dual-Device "iPhone Handoff" & Utility Upgrades
iPhone Handoff: Allows users to sync a single phone number seamlessly across two active iPhones.
Granular Audio Controls: Independent system volume controls for alarms, ringtones, media, and notifications.
Parental Controls & Safety: Introduces Ask to Browse domain filters, scheduled device time allowances, and contact approval workflows.
