Nothing OS 4.0 marks a pivotal moment in smartphone evolution. Built on the robust foundation of Android 16, this update isn’t just a refresh—it’s a reinvention. With a laser focus on minimalism, performance, and user-centric design, Nothing OS 4.0 delivers a seamless experience that feels both futuristic and familiar.
From the moment you boot up your Nothing Phone (3), the difference is palpable. The interface is cleaner, animations are smoother, and every tap feels intentional. This isn’t just software—it’s a statement.
Design
Nothing OS 4.0 embraces a design language that’s unapologetically bold yet elegantly restrained. The UI elements are refined, with squircle-shaped widgets replacing outdated layouts. The home screen now supports full-screen app folders, reducing clutter and enhancing focus.
The new Focus Zones feature allows users to create custom environments for work, entertainment, or relaxation. Each zone can have its own wallpaper, widget set, and notification preferences—perfect for multitaskers and creatives alike.
Performance Boost
Under the hood, Nothing OS 4.0 is optimized for speed and efficiency. Leveraging Android 16’s kernel enhancements, the OS delivers faster app launches, reduced background drain, and improved thermal management.
Benchmark tests reveal up to 20% faster performance on the Nothing Phone (3a) compared to OS 3.5. RAM allocation is smarter, and the adaptive battery learns your usage patterns to extend screen time without compromise.
Smart Notifications
One of the standout features of Nothing OS 4.0 is its Progress-Centric Notifications. Inspired by iOS’s Live Activities and Samsung’s Now Bar, this feature displays real-time updates from ride-share apps, food deliveries, and more—right on your lock screen.
Grouped alerts and reduced notification volume for rapid-fire apps ensure you stay informed without being overwhelmed. It’s a subtle change, but one that dramatically improves daily usability.
Eligible Devices
Nothing OS 4.0 will roll out first to the Nothing Phone (3), followed by the 3a, 3a Pro, 2, 2a, 2a Plus, and CMF Phone series. Sadly, the original Nothing Phone (1) won’t receive this update, as it has reached the end of its promised upgrade cycle.
Beta builds are expected to drop in Q3, with stable releases rolling out between September and November 2025. Users can opt-in for early access to test features and provide feedback.
Privacy and Security
Nothing OS 4.0 introduces enhanced privacy controls, including granular permission management and real-time app behavior tracking. You’ll receive alerts when apps access sensitive data like location or microphone—even in the background.
The new Zone Manager lets you isolate apps by category, restricting access based on context. For example, social media apps can be disabled during work hours, while productivity tools remain active.
Customization
Personalization is at the heart of Nothing OS 4.0. Users can now:
- Choose dynamic wallpapers that adapt to time of day
- Customize app icons with color palettes
- Set gesture-based shortcuts for quick access
- Create Focus Zones with tailored widgets and layouts
This level of control ensures your phone feels uniquely yours, without the bloat of third-party launchers.
Battery Life
Thanks to Android 16’s adaptive battery framework, Nothing OS 4.0 extends battery life by learning your habits. Apps that drain power unnecessarily are throttled, while essential services remain uninterrupted.
The new Battery Dashboard offers insights into usage patterns, charging cycles, and health metrics—empowering users to make informed decisions.
Developer-Friendly
For developers, Nothing OS 4.0 opens up new APIs for widget creation, notification customization, and Focus Zone integration. The OS supports seamless A/B testing, making it easier to optimize apps for performance and engagement.
With a growing community and open-source contributions, Nothing is positioning itself as a developer-first brand—encouraging innovation and collaboration.
Why Nothing OS 4.0 Matters
In a market saturated with incremental updates, Nothing OS 4.0 stands out as a bold reimagining of what mobile software can be. It’s not just about features—it’s about philosophy. The OS reflects a commitment to transparency, user empowerment, and aesthetic excellence.
Whether you’re a tech enthusiast, a creative professional, or someone who simply wants a phone that works beautifully, Nothing OS 4.0 delivers.
