Nothing has confirmed that the stable Android 16-based Nothing OS 4.0 update is going live from Friday, 21 November, following several weeks of open beta testing with its community. Testers who joined the Nothing OS 4.0 open beta in late October helped shape the final release, which the company is positioning as a cornerstone of its AI-first software strategy.
Eligible devices and first wave
While a final official list is still pending, the devices that took part in the open beta are expected to be first in line for Android 16 Nothing OS 4.0. This initial wave includes Nothing Phone 2 and Phone 3, along with Phone 2a, 2a Plus, 3a and 3a Pro, with models like the anticipated Phone 3a Lite and CMF-branded devices likely to follow later under existing update commitments.
Key Android 16 features in Nothing OS 4.0
Android 16 Nothing OS 4.0 blends Google’s latest platform changes with Nothing’s own UI and feature layer to deliver a more fluid, minimal experience. Among the headline additions are Extra Dark Mode, Pop-Up View for floating windows, a new 2×2 Quick Settings tile layout and refreshed lock screen clock styles designed to match Nothing’s dot-matrix aesthetic.
New tools, widgets and camera upgrades
Nothing OS 4.0 also introduces Essential Apps and user-created widgets that can be shared through the Nothing Playground, reinforcing the brand’s community-driven approach. The Android 16 Nothing OS 4.0 update brings the “Stretch” camera feature from Phone 3 to the Nothing Phone 2 series, plus a Lock Glimpse function that is disabled by default on Phone 3a models after earlier privacy concerns.
Gradual release and ecosystem impact
As with most major Android rollouts, Android 16 Nothing OS 4.0 will reach supported phones in stages, so users can expect the update to appear over the days following the general release date. For Nothing, this is the flagship software release of the year, delivering an AI-focused, more customisable interface that ties together its phones and CMF ecosystem under a consistent Android 16 Nothing OS 4.0 experience.
