Nothing has officially rolled out Nothing OS 4.0, its latest software update based on Android 16. The new operating system introduces major performance upgrades, smarter AI tools, and a redesigned interface, making it the company’s most advanced update yet.
The update will debut first on the upcoming Nothing Phone (3), before expanding to older Nothing and CMF devices. However, the original Nothing Phone (1) will not receive OS 4.0, as its official software support cycle has ended.
A Redesigned Interface for a Cleaner Look
With OS 4.0, Nothing has focused on standardizing its design language. The refreshed interface features new lock screen clock styles, a simplified Quick Settings panel, and smoother animations.
The update also refines the Always-On Display, improves brightness controls, and makes the lock screen more responsive, creating a smoother everyday experience for users.
TrueLens Engine: Camera and Gallery Upgrades
One of the biggest highlights of Nothing OS 4.0 is the TrueLens Engine, a system designed to improve both the Camera and Gallery apps.
Users get access to new creative presets, upgraded controls, and a cleaner layout that simplifies photo capturing and browsing. The gallery experience is now more intuitive and visually engaging, making it easier to manage and relive memories.
AI Usage Dashboard and Transparency Features
AI is at the center of Nothing OS 4.0, but with a focus on transparency and user control. The new AI Usage Dashboard allows users to see how AI functions are being used on their devices.
The system also includes AI (LLM) status hints, giving real-time information about when and how AI is active. This ensures users can make informed choices about their privacy while still benefiting from AI-driven tools.
Improved Connectivity and Smarter Multitasking
Nothing has fine-tuned connectivity features in OS 4.0. Bluetooth and Wi-Fi connections are now more stable, with faster pairing and smoother device switching. There’s also quicker access to Bluetooth recording for easier audio capture.
For multitasking, the new Pop-up View stands out. This feature lets users run two floating apps simultaneously, manage them with simple swipe gestures, and expand them to full screen when needed. It’s a small change that makes multitasking more efficient and flexible.
Performance and Stability Refinements
Under the hood, Nothing OS 4.0 delivers a noticeable boost in speed and reliability. App launches are faster, system navigation feels smoother, and background app management has been optimized to improve responsiveness.
The result is a more stable, fluid performance, even when multiple apps are running in the background. This ensures that Nothing devices continue to feel snappy and reliable over time.
Device Rollout: Who Gets the Update?
The first device to launch with Nothing OS 4.0 will be the Nothing Phone (3). Following that, newer models from Nothing and CMF will gradually receive the update.
However, the Nothing Phone (1) will not be upgraded. The company has confirmed that the model has reached the end of its software lifecycle, meaning users will need to upgrade to a newer device to experience OS 4.0.
Why It Matters
The launch of Nothing OS 4.0 signals the company’s push to combine design, AI, and performance into one cohesive experience. By focusing on a redesigned interface, AI transparency, and faster performance, Nothing is positioning itself as a strong player in the Android ecosystem.
For users, this update means a smarter, more polished smartphone experience with features that rival premium flagships. As it begins rolling out, OS 4.0 will likely become one of the biggest talking points for Android enthusiasts this year.
