Nothing OS 4.0 Based on Android 16 Now Rolling Out to Nothing Phone (3)
Nothing has officially begun the stable rollout of Nothing OS 4.0, built on Android 16, starting with the Nothing Phone (3). This major software update arrives after an extensive beta testing period and delivers significant enhancements to the company's signature user experience.
Key Features and Interface Refinements
The update introduces Live Updates, which deliver real-time information for rides, deliveries, and timers directly to the screen and Glyph Interface. This unification of lock-screen notifications and light-based cues allows users to track progress instantly without opening apps. Any application supporting Android 16's Live Updates feature will automatically work with Nothing's Glyph Progress system, significantly expanding compatibility beyond previous limitations.
Visual improvements include a refined Extra Dark Mode that deepens blacks, improves contrast, and reduces power consumption across the system. The interface adopts a calmer, more focused aesthetic for notifications, quick settings, and the app drawer, enhancing both comfort and visibility in low-light conditions. This darker theme now extends to first-party apps like Essential Space and Launcher, with broader integration expected in future updates.
Enhanced User Experience and Interactions
Nothing OS 4.0 significantly improves the tactile feel of the operating system. Every touch, swipe, and gesture now responds with more depth and physical feedback. Subtle haptic feedback appears at volume maximum and minimum points, providing immediate physical response even when not looking at the screen. App opening and closing animations feel smoother and more immersive, with the home screen background gently scaling to create a sense of depth and connection.
Notification interactions have been refined with subtle weight and rebound effects, creating a smooth, responsive flow throughout the interface. The update also introduces more widget sizes, including new 1×1 and 2×1 layouts for Weather, Pedometer, and Screen Time, allowing users to build balanced, minimal home screen setups.
Productivity and Customization Features
Multitasking receives a boost with Pop-up View, enabling users to open two floating apps simultaneously and switch between them with simple gestures. Swiping up from the bottom minimizes apps, while pulling down expands them to full screen. For organization, users can now hide any app from the App Drawer while maintaining access with a simple swipe, helping to simplify home screens and create personalized layouts.
Phone (3)-specific enhancements include deeper Flip to Glyph controls, a refined Pocket Mode, and new Glyph Toys like Hourglass and Lunar Cycle. The Mirror Selfie feature now saves the original photo as an extra image in the Gallery alongside the mirrored version.
Rollout Strategy and Future Availability
The update is currently rolling out to Nothing Phone (3) devices first, with other Nothing and CMF devices scheduled to follow. The company has not committed to specific timeframes for other models at this time. As with most software updates, the rollout is expected to occur in stages, meaning some users might experience brief delays before receiving the update notification.
Conclusion
Nothing OS 4.0 represents a significant step forward in the company's software development, bringing Android 16's latest features while enhancing the distinctive Nothing experience. The update focuses on improving both visual polish and practical functionality, with particular attention to the Glyph Interface, haptic feedback, and user customization. For Nothing Phone (3) owners, this update delivers on the company's promise of timely software support while introducing meaningful improvements to daily smartphone use.
