Nothing OS 4.0 Based on Android 16 Rolling Out to CMF Phone 1, CMF Phone 2 Pro, and Nothing Phone 3a Lite

Nothing is widening the release of Nothing OS 4.0. The update is reaching CMF Phone 1, CMF Phone 2 Pro, and Nothing Phone (3a) Lite. These join Nothing Phone (3), which received Nothing OS 4.0 in November.

Nothing confirmed the rollout in a post on the Nothing Community forum. Nothing OS 4.0 is based on Android 16 and centres on consistency and usability. Visual tweaks, new interface options, and smoother daily interactions are central to this release.

Nothing OS 4.0 Regional Availability and Timeline Details

Nothing expects CMF Phone 2 Pro to get Nothing OS 4.0 within weeks. Nothing Phone (3a) Lite should start receiving the update in early January. The company warned that regions and deployment batches can change exact availability.

Nothing OS 4.0 mainly aims to polish the experience on supported CMF and Nothing phones. The update emphasises coherent design, steady performance, and familiar behaviour. It avoids major new core features that could disrupt how devices already work.
