Nothing has unveiled Nothing OS 4.0, its Android 16–based platform update. The company says an open beta will start soon after closed testing, with the Phone 3 getting the update first and newer Phone 2 series models following.

Quick summary

  • Base: Android 16, with Nothing’s visual redesign and system refinements.
  • Key UI changes: sharper, more standardised components, redesigned lock-screen clocks, and cleaner Quick Settings.
  • New features: Extra Dark Mode, pop-up/multitasking view, TrueLens camera improvements, and an AI usage dashboard for transparency.
  • Rollout: closed beta already on Phone 3; open beta expected soon, no stable release date yet. Phone 2 and Phone 2a/3a and supported CMF phones will follow.

What’s new in Nothing OS 4.0

Nothing OS 4 focuses on a cleaner, more thoughtful UI, battery-saving Extra Dark Mode, improved multitasking with floating/pop-up app views, and camera improvements via the TrueLens Engine. The OS also includes an AI dashboard that surfaces which on-device or cloud models are active and a set of controls for AI features.

Devices likely to get the update

Nothing intends to begin with the Phone 3 and then expand to Phone 2, Phone 2a, Phone 3a, and other supported CMF devices according to its update commitments. The original Phone 1 is less likely to be included. Exact eligibility and timing will depend on hardware and certification.

Beta access and how to join

Nothing ran closed beta signups for Phone 3; an open beta program is promised soon via the Nothing Community and official channels. If you want early access, keep an eye on Nothing’s community posts and the official update page.

Should you update?

If you use a supported Nothing phone and value new Android 16 features plus Nothing’s visual refresh and AI controls, the beta is worth trying only if you are comfortable with pre-release bugs. Wait for the stable release on your daily driver unless you enjoy testing.
