Nothing OS 4.0: Release Date & Rollout Schedule
Nothing has officially outlined a staged rollout for OS 4.0, starting with developer previews and moving to public betas before the stable release.
Release Schedule:

What’s New in Nothing OS 4.0?
Nothing OS 4.0 is built over Android 16 and promises better performance, fresh design elements, and smarter system intelligence. Here’s a breakdown of its key upgrades:
| Feature Area | Improvements in Nothing OS 4.0 |
|---|---|
| Android Version | Based on Android 16 |
| Design Language | More refined minimalist UI with smoother animations |

These updates will be most noticeable on the Nothing Phone 3, and optimized for the Nothing Phone 3a as well, despite its slightly different hardware setup.
Android 16 Features on Nothing Devices
Android 16 brings a set of new features to all supported devices, but Nothing customizes them further for its OS. Here’s a comparison of standard Android 16 features and how they’ve been adapted in Nothing OS 4.0:

The Nothing Phone 3a benefits from most of these features, though some advanced Glyph integrations may be simplified for efficiency.
