After a brief pause to address critical issues, Nothing has resumed the rollout of its major Nothing OS 4.0 update, this time extending it to its more affordable CMF-branded devices. This move marks a significant expansion of the Android 16-based software, bringing its refreshed interface and new features to a wider user base. The update's staggered release highlights the company's cautious approach following earlier bugs, aiming to deliver a smoother experience to its community.
The Rollout Resumes for Budget Devices
Nothing has officially confirmed the stable rollout of Nothing OS 4.0 for the CMF Phone 1, which began on 26th December 2025. This follows a period where the update was halted due to undisclosed critical bugs that affected the initial release on flagship models. The company is now proceeding with a phased, region-by-region deployment for the CMF Phone 1, meaning not all users will receive the update notification simultaneously. Owners are advised to manually check their device's settings for the software update.
Nothing OS 4.0 Rollout Schedule:
- CMF Phone 1: Stable rollout began December 26, 2025 (phased, region-dependent).
- CMF Phone 2 Pro: Scheduled for rollout "in the coming weeks."
- Nothing Phone (3a) Lite: Rollout begins "at the beginning of January."
Expanded Device Support and Timeline
The update wave is not limited to a single model. Nothing has outlined a clear timeline for its subsidiary devices. Following the CMF Phone 1, the more recent CMF Phone 2 Pro is scheduled to receive the Nothing OS 4.0 update "in the coming weeks." Furthermore, the Nothing Phone (3a) Lite is slated to begin its update cycle at the beginning of January. This structured approach allows Nothing to manage server load and monitor for any device-specific issues that may arise during the deployment.
Update Key Details:
- Base: Android 16
- Version: Nothing OS 4.0 (stable)
- Focus: Refined UI, deeper system customization, performance and stability improvements.
- Previous Status: Rollout was previously halted due to critical bugs.
What Nothing OS 4.0 Brings to the Table
Based on Android 16, Nothing OS 4.0 is described as bringing a "more refined and personal experience" to supported devices. The update focuses on visual refreshes across the system interface, offering users deeper customization options to tailor their phone's look and feel. Beyond aesthetics, the update includes under-the-hood improvements designed to enhance overall system smoothness, stability, and everyday usability, addressing the core user experience that was reportedly impacted by the initial bugs.
A Cautious Yet Progressive Software Strategy
The resumption of the Nothing OS 4.0 rollout, particularly to budget devices, signals Nothing's commitment to its entire product ecosystem. The decision to halt and then carefully restart the update demonstrates a responsible approach to software management, prioritizing stability over speed. For users of CMF devices, this update represents a significant value addition, bringing flagship-grade software features and the latest Android security foundations to more accessible hardware, effectively extending the lifespan and capability of their phones.
