Nothing OS 4.0 Update Rolling Out on November 21: New Features, Design and Speed Boost

Nothing OS 4.0 Update for Nothing Phones Starts November 21 with Major UI and Speed Upgrades

Introduction

Nothing has confirmed that the stable Nothing OS 4.0 update will begin rolling out on November 21. This is a major Android 16 based software release called Flow, designed to improve speed, visual polish and everyday usability across Nothing phones. The global rollout begins on Friday, with the Nothing Phone 3 receiving it first, followed by other models in a phased schedule. After months of open beta testing, the stable version is ready with features such as better multitasking, an improved dark mode, new camera presets and faster app launches. The update aims to blend style and function while keeping privacy in focus through on device controls and clear settings for new lock screen options.

Rollout and Eligibility

The stable rollout of the Nothing OS 4.0 update starts worldwide on November 21. Nothing has stated that the Nothing Phone 3 will be the first device to receive it. Other eligible models will get the update in stages to make sure the rollout remains stable and smooth across all regions. Community and media reports have also highlighted the phased schedule.

Multitasking Upgrades

A new pop up view allows users to run two apps at the same time in floating windows. This makes it easier to read a document while composing an email or keep a chat open during video playback without switching through the recent apps menu. These improvements aim to reduce unnecessary taps and support users who often juggle quick tasks, especially creators and multitaskers.

Design and Display

Extra Dark Mode offers a deeper and more comfortable system theme for nighttime use, which can help reduce eye strain on OLED screens. The Flow visual refresh introduces a cleaner layout for quick settings and lock screen elements, giving the interface a more simple and fluid appearance.

Camera Tools

The update introduces a Stretch camera preset developed in collaboration with photographer Jordan Hemingway. It adds deeper shadows and brighter highlights to deliver a cinematic look directly from the camera app. This helps users create styled portraits and dramatic scenes with one tap, without needing extra editing.

Lock Screen Features

Lock Glimpse provides curated wallpapers across nine categories. It is off by default, and Nothing says it does not collect personal data even when users choose to enable it. The feature is designed to update the lock screen visually while still giving users full control through settings.

Performance and System

System wide app optimizations are included in the Nothing OS 4.0 update, targeting faster app startup and smoother animations across supported phones. The Android 16 base also brings platform improvements, which Nothing has combined with its own design updates and AI tools for a more responsive user experience.

What Users Should Do

Users can manually check for the update in the system settings from November 21 onwards. It is recommended to download the update over Wi Fi and back up important data before installing it. If the update does not appear on the first day, users should wait for the staged rollout to reach their device, as the build will expand to more models gradually.

Analysis by editor 

The Nothing OS 4.0 update strengthens Nothing’s software strategy with a mix of practical upgrades and visual refinements built on Android 16. Features such as pop up multitasking and Extra Dark Mode add real value for people who want fewer taps and more comfort during long use. The Stretch camera preset gives the phone a creative edge in a crowded premium market where software tuning often sets brands apart. The decision to start with the newest model and then expand the rollout shows a clear focus on stability and real world testing. This approach should help users across regions enjoy a smooth and reliable upgrade process.
