Nothing OS 4.0, Based on Android 16, Rollout Starting Soon: What to Expect
Nothing OS 4.0, the London-based smartphone brand led by Carl Pei, is preparing to release its next big software update, Nothing OS 4.0. Built on top of Android 16, this update is shaping up to be the company’s most polished version yet. After weeks of teasers and closed beta testing, the rollout is expected to begin very soon, starting first with the latest devices and gradually expanding to older models. For users, this means a refreshed design, new features, and deeper system improvements that will define the future of Nothing’s phones.

A Step Forward in Design
Nothing has always focused on offering a clean and minimal software experience, and OS 4.0 takes this to the next level. The update is designed around the theme “Refined. Redefined.” which signals that this is more than just a small update. Icons, widgets, and quick settings toggles are getting a major visual overhaul. Users will notice that some toggle icons, such as the flashlight, are now circular with bold color highlights. Brightness controls and dark mode switches also adopt a more rounded, modern look. Nothing is also introducing new pill-shaped switches and redesigned sliders that feel more consistent across the system. Overall, the interface looks smoother, more cohesive, and easier to use.
New Features and Improvements
Beyond the visual polish, Nothing OS 4.0 introduces several functional upgrades. Since it is based on Android 16, it brings along all of Google’s improvements, such as stronger security protections, better power management, and improved privacy tools. Notifications are more refined, battery optimization is smarter, and app handling should feel faster.
On top of Android 16’s base, Nothing has layered its own innovations. Users can expect more interactive widgets, easier customization, and system intelligence that makes the phone feel more personal. For example, widgets like weather, brightness, and to-do lists are expected to be more dynamic. The update may also include subtle AI-powered touches, like smarter suggestions or predictive shortcuts, making the phone act less like a tool and more like a helpful companion. Performance is another area of focus. With OS 4.0, animations are smoother, apps launch quicker, and background processes are better optimized. Gamers should see improved stability during long sessions, while casual users will notice better battery endurance in day-to-day use.
Nothing OS 4.0 2025 : Eligible Devices
Not all Nothing phones will get the new software. The rollout will begin with the Nothing Phone 3 series, which includes the standard and Pro models. From there, the update will extend to the Phone 2, Phone 2a series, and the 3a lineup. Additionally, Nothing’s sub-brand CMF Phones are also included, ensuring that even budget-friendly models benefit from the new experience.
Unfortunately, Nothing Phone 1 owners will not receive the update. That device has reached the end of its promised major OS support. While this may disappoint early adopters, it’s common for brands to phase out older models once their update cycles are complete. Phone 1 users will likely still get smaller security patches, but the full OS 4.0 upgrade won’t be available to them.
Rollout Timeline
The stable rollout of Nothing OS 4.0 is expected to begin very soon, likely starting within this season. As is typical with major updates, the release will happen in phases. The Phone 3 will be the first to receive it, followed by the other eligible models in the coming weeks. Depending on your region, it may take some time for the update to reach your device, so patience will be key.
What Users Should Do Before Updating
Big OS updates require preparation. Users should make sure they have at least a few gigabytes of free storage space, a strong internet connection, and their phones charged to at least 50%. It’s also a good idea to back up important photos, documents, and app data before downloading the update. While Nothing has tested OS 4.0 through beta programs, the first stable versions can still carry small bugs, so being ready is wise.
Why This Update Matters
Nothing OS 4.0 represents the company’s effort to refine its identity. Since its launch, the brand has emphasized transparency and minimalism, and this update shows its maturity. With Android 16 as the backbone, the update offers cutting-edge security and performance, while Nothing’s own design language ensures that the software feels unique and instantly recognizable. For users upgrading to OS 4.0, the experience will feel cleaner, faster, and more reliable. For Nothing itself, this update is a statement that it is no longer a small newcomer but a brand that can deliver long-term support and innovation.
Final Thoughts
The arrival of Nothing OS 4.0 marks an important milestone for the company. Users can look forward to a refreshed interface, smarter features, and the solid foundation of Android 16. While not every device will receive it, those with newer models like the Phone 3, Phone 2, and CMF
