Nothing has officially rolled out the stable version of its Android 16-based Nothing OS 4.0 for the CMF Phone 1, bringing a fresh wave of design enhancements and usability improvements to the budget-focused smartphone. The update marks a significant step forward for CMF users, delivering a more polished and personalized software experience.
According to the company, Nothing OS 4.0 focuses on refining everyday interactions through visual updates, expanded customization options, and performance optimizations. The interface has received subtle but noticeable design tweaks aimed at making the system feel cleaner, more intuitive, and easier on the eyes during extended use. These refinements align with Nothing’s signature minimalist aesthetic while improving overall usability.
Customization has been a major highlight of the update. Users can now enjoy deeper system-wide personalization, allowing them to tailor the look and feel of their device more closely to their preferences. From interface elements to system behavior, Nothing OS 4.0 gives users greater control without compromising simplicity or performance.
Performance and stability improvements are also part of the update package. Nothing says the new software is designed to make daily use smoother and more comfortable, with optimizations that improve responsiveness and reduce friction during common tasks. These enhancements are particularly important for mid-range devices like the CMF Phone 1, where efficient software plays a key role in the overall user experience.
The stable update is being rolled out in phases, meaning not all users will receive it at the same time. CMF Phone 1 owners can expect the update to arrive gradually over the coming days, depending on region and device configuration. Users are advised to keep an eye on system update notifications or manually check for updates through their device settings.
Looking ahead, Nothing has confirmed that the CMF Phone 2 Pro will receive the Nothing OS 4.0 update in the coming weeks. Meanwhile, the Nothing Phone (3a) Lite is scheduled to start receiving the Android 16-based update at the beginning of January.
With this rollout, Nothing continues to strengthen its software ecosystem, ensuring timely updates and a consistent user experience across its growing lineup of smartphones.
