Nothing expanded its public rollout of Nothing OS 4.0, based on Android 16, to CMF Phone 1, CMF Phone 2 Pro, and Nothing Phone (3a) Lite. The wider rollout follows the stable release that first began reaching Nothing Phone (3) in November.
The company confirmed the update through a post on the Nothing Community forum. According to the announcement, Nothing OS 4.0 includes visual changes across the system, expanded customisation options at the interface level, and refinements intended to improve everyday device interaction. The update focuses on improving consistency and usability rather than introducing new core features.
Rollout details and device timeline
The update is being released in phases:
- CMF Phone 1: The public rollout begins today, with availability expanding gradually.
- CMF Phone 2 Pro: Scheduled to receive the update in the coming weeks as part of the phased rollout.
- Nothing Phone (3a) Lite: Expected to start receiving Nothing OS 4.0 in early January, completing the general release.
Nothing states that rollout timing may vary by region and deployment batch.
