Nothing has officially expanded the public rollout of Nothing OS 4.0, its latest software update based on Android 16, to more devices across its ecosystem. The update is now reaching CMF Phone 1, with CMF Phone 2 Pro and Nothing Phone (3a) Lite scheduled to follow soon.

This wider availability comes after the stable release of Nothing OS 4.0 first began rolling out to the Nothing Phone (3) in November, marking the next phase in Nothing’s broader software update strategy.

Official Confirmation via Nothing Community

The company confirmed the expanded rollout through an announcement on the Nothing Community forum. According to Nothing, OS 4.0 focuses on refining the overall user experience with visual consistency, interface-level customisation, and subtle usability improvements rather than introducing major new features.

The update reflects Nothing’s design-first philosophy, prioritising clarity, smooth interactions, and everyday usability across supported devices.

What’s New in Nothing OS 4.0

Nothing OS 4.0 introduces a series of system-wide refinements aimed at improving how users interact with their phones daily. Key highlights include:

Refreshed visual elements across the interface for improved consistency

Expanded customisation options, allowing users to personalise layouts and system behaviour more deeply

UI refinements focused on smoother navigation and cleaner transitions

Usability improvements designed to make common actions more intuitive

Rather than adding entirely new core functions, the update concentrates on polishing existing features to deliver a more cohesive Android experience.

Rollout Timeline and Supported Devices

Nothing OS 4.0 is being released in phases, with availability varying by device and region. The confirmed rollout plan includes:

CMF Phone 1

The public rollout begins now

Availability will expand gradually across regions and batches

CMF Phone 2 Pro

Scheduled to receive the update in the coming weeks

Part of the same phased deployment strategy

Nothing Phone (3a) Lite

Expected to start receiving Nothing OS 4.0 in early January

This will complete the general rollout across the newly announced devices

Nothing has noted that exact rollout timing may differ depending on region, carrier approvals, and deployment batches.

Focus on Consistency Over New Features

With Nothing OS 4.0, the company appears to be prioritising software maturity over rapid feature expansion. The emphasis is on making the interface feel more unified across devices, improving visual harmony, and ensuring smoother performance in daily use.

This approach aligns with Nothing’s long-term goal of delivering a clean, distinctive Android experience that remains reliable and intuitive as the ecosystem grows.

What This Means for CMF and Nothing Users

The expansion of Nothing OS 4.0 to CMF-branded devices highlights Nothing’s commitment to providing timely software updates across its wider product lineup, not just flagship models. For users, this means:

Faster access to the latest Android version

A consistent software experience across Nothing and CMF devices

Ongoing UI and usability improvements without disrupting familiar workflows

Conclusion

The expanded rollout of Nothing OS 4.0 to CMF Phone 1, CMF Phone 2 Pro, and Nothing Phone (3a) Lite marks an important step in Nothing’s software roadmap. By focusing on visual refinement, customisation, and usability enhancements, the company is reinforcing its identity as a design-driven Android brand.

As the phased rollout continues into January, more users across regions can expect a cleaner, more consistent, and polished Android 16 experience on their Nothing and CMF smartphones.
