CMF by Nothing has officially begun rolling out a significant software upgrade for its popular budget smartphone. The CMF Phone 1 is now receiving the NothingOS 4.0 update, which is built on the latest Android 16 platform. This move marks a notable step in bringing cutting-edge software features to an affordable device segment.
What's New in NothingOS 4.0 for CMF Phone 1?
The update, announced on 29 December 2025, packs a host of enhancements designed to improve both the visual experience and user privacy. A standout addition is the Extra Dark Mode, which promises deeper blacks and reduced eye strain in low-light conditions, going beyond the standard dark theme offered by many systems.
Users can also look forward to a refreshed set of widgets that offer more customization and at-a-glance information directly on the home screen. Furthermore, the update focuses on refining the user interface with smoother animations, aiming to make every swipe and tap feel more fluid and responsive.
Enhanced Privacy and User Experience
Alongside the visual tweaks, NothingOS 4.0 introduces enhanced privacy features. While the exact details of these privacy tools were not fully disclosed in the initial announcement, such updates typically include better permissions management and increased transparency over how apps access data.
The rollout demonstrates CMF's commitment to providing substantial post-purchase support for its devices. Updating the CMF Phone 1 to Android 16 ensures it remains secure and competitive with newer models entering the market.
Availability and Implications
The update is being released in a phased manner, meaning it may take a few days to reach all eligible CMF Phone 1 units globally. Users are advised to check their system settings manually for the update notification.
This strategic update is significant for the brand's reputation in the value-focused market. By delivering a major Android version jump coupled with a custom skin overhaul, CMF by Nothing strengthens its position as a brand that offers a premium software experience without a premium price tag. It directly addresses user demand for longer software support cycles in the budget smartphone category.
