Nothing OS 4.0 has officially begun rolling out, bringing a refined, faster, and more visually cohesive experience to Nothing devices. Built on the strong foundation of OS 3.0, this update focuses heavily on what truly shapes day-to-day use: speed, fluidity, and consistent design. The system feels lighter, cleaner, and more responsive—created with the intention of removing small points of friction that get in the way of a smooth mobile experience.

Icons have been reimagined with a calmer, more minimal look. Animations feel snappier and more precise. UI components follow a clearer structure, creating a sense of order throughout the system. OS 4.0 is all about tightening the fundamentals and preparing the platform for what’s ahead.

Refined by You

This update wouldn’t be what it is without the Open Beta Test community. The OBT provided real-use insights that helped the team identify issues, prioritise features, and refine the final build. Each beta release targeted specific areas so Nothing could tune the experience with precision.

Feedback from testers led to several improvements—from more consistent visuals and redesigned status bar icons to a cleaner lock screen password interface and smoother system animations. Users also shared input on multitasking, inspiring enhancements like the revamped Pop-up View and new Quick Settings layouts.

Another key theme was glanceability, which guided the introduction of Live Updates on both the lock screen and the Glyph Interface. Now, tracking rides, deliveries, and timers is more seamless than ever.

Thank you to everyone who took the time to shape this release.

Visuals & Interaction. Calm and Fast.

OS 4.0 brings a renewed sense of flow to Nothing devices. Motion and physics feel more natural, transitions are smoother, and the UI has been unified to deliver a clean, balanced aesthetic.

Refreshed First-Party Icons

Native app icons now adopt a quieter, more minimal appearance. The entire home screen feels more intentional and visually harmonious.

Refined Status Bar Icons

Status bar elements—such as Wi-Fi, cellular data, and battery indicators—have been redesigned for clarity and consistency. They now mirror the visual language introduced with Android 16, making information easier to read at a glance.

New Lock Screen Clocks

Two fresh clock styles with bold, futuristic designs join the lock screen lineup. Paired with updated typography, they offer a distinctly Nothing look.

Interaction Animations

Animations have been tuned with more tactile responsiveness. Whether you’re pulling down the Notification Shade or switching apps, movements feel sharper and more grounded.

Haptic Feedback at Limits

Subtle haptic cues now activate when you hit the maximum or minimum volume level. It’s a small but meaningful detail that makes device interaction more intuitive.

Functional Flow. Cancel Distractions.

OS 4.0 introduces thoughtful features that help you stay focused and maintain momentum during your day.

Glyph Progress

Glance at your phone—or even away from it—to see progress updates via the screen or the Glyphs. Deliveries, rides, and timers now integrate seamlessly without relying on specific partner apps. With Android 16’s broader compatibility, support for more apps will roll out quickly.

Refined Pop-up View

Multitasking becomes easier with the ability to open two floating apps at once. Quick gestures let you reposition or switch between windows without disrupting your workflow.

Extra Dark Mode

A deeper, more comfortable dark appearance reduces eye strain and improves battery life. It also enhances visibility in low-light settings without washing out details.

Hidden Icons

You can now hide apps in the App Drawer without moving them to a private space. Your setup stays clean, while the apps remain accessible via search.

More Widget Sizes

New 1×1 and 2×1 widget options for Weather, Pedometer, and Screen Time help create tighter, more personalised Home screen layouts.

System and App Optimisation

The new dashboard presents a clear overview of background activity and gives you one-tap access to performance optimisation tools—keeping your phone smooth without extra effort.

Universal Search Settings

Refine exactly what search includes, helping you find information faster.

Creativity. Unlock Your Flow.

Playground is one of the most exciting additions to Nothing OS, offering a new way to bring ideas to life through AI.

Essential Apps (Playground)

Create widgets just by describing what you want—no coding required. AI handles the building process, turning your ideas into functional widgets instantly.

Widget Drawer

All your custom and community-sourced widgets live in a tidy, organised drawer. It’s now easier to manage, rearrange, and share your creations.

Your device becomes a space where creativity and personal expression can thrive.

Privacy. Transparent Intelligence.

As Nothing introduces deeper AI features, transparency remains a priority. The new AI Status Hints show exactly when an AI model is running, right from your status bar. An accompanying dashboard lets you review usage so you always know how and when AI is assisting you.

Phone (3) Exclusives

Phone (3) owners get a few unique experiences that make use of the device’s hardware:

Glyph Mirror Selfie

Capture futuristic, stylised selfies using the Glyph Interface as a light source. These mirrored shots save directly to your Gallery for easy sharing.

Smarter Flip to Glyph

When placing your phone face-down, you can now choose whether the device switches to Vibrate or Silent mode—giving you better control over distractions.

Pocket Mode

The Glyph Matrix intelligently disables while the phone is in your pocket, saving battery and preventing accidental triggers.

New Glyph Toys

Two new time-themed visual experiences arrive:
• Hourglass, visualising the flow of time
• Lunar Cycle, showing the moon’s current phase above your location

Essential Memory. Your Second Brain.

Essential Memory takes the existing Essential Space and Essential Search to the next level. Instead of just storing what you save, your phone can now understand and recall it more naturally.

Save something—like an event poster tagged “April events”—and later simply ask, “What’s coming up next month?” Your phone retrieves it instantly. Essential Space stores it, Memory interprets it, and Search finds it.

This smarter memory layer will arrive soon in an upcoming Essential Space update.

Rollout Status

The public rollout of Nothing OS 4.0 begins today for Phone (3). Other Nothing devices will receive it in the coming weeks, with CMF phones planned to follow by the end of the year. Phone (3a) Lite users can expect the update early next year.
