Nothing has officially begun rolling out Nothing OS 4.0, marking the company’s latest major software update and its first release built on Android 16. The rollout starts today with the flagship Phone (3), and at least on paper, the focus is clearly on speed, stability, and making everyday interactions feel a bit more deliberate. It does not feel like a dramatic reinvention, but rather a steady refinement of what Nothing has been building toward over the past few releases.
With Nothing OS 4.0, the brand is leaning into a cleaner visual language, more responsive system behavior, and deeper integration of its distinctive Glyph Interface. The goal, it seems, is to make common tasks quicker while also giving users more control over how their phone communicates information back to them. That balance between minimalism and functionality is still very much at the center of Nothing’s design philosophy.
Key Takeaways
- Nothing OS 4.0 is now rolling out for Phone (3) users.
- The update is built on the Android 16 operating system.
- Glyph Progress now supports live updates for rides, deliveries, and timers.
- A new AI Status Dashboard improves transparency around AI usage.
- CMF devices and Phone (3a) Lite will receive the update later.
Faster Performance and Visual Changes
One of the first things users are likely to notice is how responsive the system feels. Nothing has refined animations and gestures so they react more immediately to touch, which makes general navigation feel smoother than before. The company has also refreshed icons for its own apps, along with tweaks to the status bar, making key information easier to spot at a glance.
There are a few subtle additions as well. Users can choose between two new lock screen clock styles, and volume adjustments now come with gentle haptic feedback. These are small changes, but together they add a sense of polish that was perhaps missing in earlier versions.
Multitasking has received some attention too. Pop-up View now supports two floating windows at the same time, which is useful if you tend to juggle apps frequently. Quick Settings can be arranged in a compact 2×2 tile layout, and widgets are now available in a tiny 1×1 size. These smaller widgets can display things like step counts, weather updates, or screen time without overwhelming the home screen. You can also hide specific apps in the app drawer, which helps keep things visually tidy if you have a lot installed.
Glyph Progress and Privacy Updates
The Glyph Interface remains one of Nothing’s most recognizable features, and in Nothing OS 4.0 it becomes more practical. Glyph Progress is now capable of tracking live activities such as ride-hailing arrivals or food delivery timers. Instead of constantly checking the screen, users can glance at the LED lights on the back of the phone or the lock screen to see how things are progressing.
What is interesting here is that Glyph Progress is no longer limited to a small set of partner apps. Nothing says support will expand to more services over time, which could make this feature genuinely useful rather than just visually interesting.
On the privacy front, Nothing is taking a more transparent approach to artificial intelligence. The new AI Status Dashboard shows exactly when an AI model or large language model is active on your device. This makes it easier to understand when data is being processed by smart features, which is something many users have been asking for, even if they do not always articulate it directly.
Exclusive Features for Phone (3)
Some features are reserved specifically for the Phone (3), taking advantage of its hardware. One of these is Glyph Mirror Selfie, which uses the rear LED lights to help frame selfies taken with the main camera. It sounds niche, but for people who care about camera quality, it could be surprisingly useful.
There are also new playful additions known as Glyph toys, including Hourglass and Lunar Cycle. These are less about productivity and more about interaction, offering creative ways to use the light strips beyond notifications. Whether everyone will use them regularly is debatable, but they do fit the brand’s personality.
Looking ahead, Nothing has also teased a feature called Essential Memory. This upcoming system will allow users to save content and retrieve it later using natural language search. It builds on the existing Essential Search tool and aims to make finding photos, notes, or documents feel more intuitive. It is not fully available yet, but it gives a sense of where Nothing is heading.
Availability in India
Nothing OS 4.0 is currently rolling out to Phone (3) devices in India and select other regions. If you own a CMF by Nothing smartphone, the update is expected to arrive by the end of 2025. Meanwhile, the more affordable Phone (3a) Lite is scheduled to receive the update in early 2026. The staggered rollout is not surprising, though it may test the patience of some users.
