“Nothing OS 4.0 Rolls Out With Android 16, AI Dashboard & Fresh UI for Phone 3a Series” 


Android 16-Based Update Begins Rolling Out

Nothing has officially kicked off the stable rollout of Nothing OS 4.0, its newest software version built on Android 16, for the Phone 3a and Phone 3a Pro. The update brings a refreshed interface, redesigned system icons, deeper AI controls, an upgraded Essential Space, and several quality-of-life improvements across the UI.

The company confirmed on its community forum that version B4.0-251118-1551 is now being delivered in phases. Users can manually check for the latest package by heading to
Settings → System → System Update.


Major Changes in Nothing OS 4.0

AI Usage Dashboard

A new AI Usage Dashboard gives users more visibility into how large-model AI tools operate inside Essential Space. This offers improved transparency and greater control over when and how AI processes run.


Enhanced App Management

Nothing OS 4.0 introduces the ability to hide apps directly from both the Home Screen and App Drawer.
Hidden apps can be viewed under:
Home Screen → App Drawer → Hidden Icons


Widget Improvements

Several widgets have been updated with additional size options, including:

  • Weather
  • Pedometer
  • Screen Time

Quick Settings tiles now widely support a 2x2 layout for better organization.


Performance and Functional Updates

The update boosts startup performance, improves the Flip to Record feature, and introduces early versions of Playground (Alpha) and Essential Apps (Alpha).


Design & UI Upgrades

Refreshed Visual Elements

Nothing OS 4.0 adds:

  • Reimagined Nothing app icons
  • Smoother transition animations
  • Updated status bar elements
  • Two new lock-screen clock designs

A new Extra Dark Mode can be enabled via:
Settings → Display → Dark theme → Extra dark mode


Glyph & Camera Enhancements

The update also includes:

  • The option to decide whether Flip to Glyph triggers Silent Mode or Vibrate
  • Glyph Progress integration with Android 16’s Live Update notifications
  • Camera feature enhancements including new presets, filters, watermarks, Motion Photos, and a refined interface
