Android 16-based Nothing OS 4.0 brings AI features, new design language, and smarter performance
Tech enthusiasts, mark your calendars — the long-awaited Nothing OS 4.0 stable release is finally happening. After weeks of speculation and open beta testing, London-based tech brand Nothing has confirmed that its latest Android 16-based update, codenamed “Flow,” will begin rolling out globally on November 21, 2025.
According to a report from The Times of India, the Nothing OS 4.0 update will introduce a wave of new features designed to make Nothing’s smartphones “smarter, smoother, and more connected.” The company has positioned this release as a core step in its AI-first strategy, blending sleek design with intelligent customization.
Nothing OS 4.0 Update Release Date and Availability
Nothing officially confirmed the nothing os 4.0 update release date via its community forum and social media channels. In a post on X (formerly Twitter), the company wrote:
“Nothing OS 4.0. Let your phone bring flow to your life. General Release. 21 Nov.”
The rollout begins on November 21 for supported devices, with wider availability expected over the following week.
Based on the open beta list, the Nothing OS 4.0 stable release will first reach the following smartphones:
- Nothing Phone 2 and 3 series
- Nothing Phone 2a and 2a Plus
- Nothing Phone 3a and 3a Pro
A later phase of the rollout may include additional models such as the Nothing Phone 3a Lite, as well as upcoming devices under Nothing’s CMF sub-brand, which shares the same operating system foundation.
What’s New in Nothing OS 4.0
The nothing os 4.0 update builds on the company’s minimalist design philosophy while adding deeper AI-driven functionality. Powered by Android 16, the release includes performance enhancements, smarter app management, and improved multitasking capabilities.
Key New Features:
- Extra Dark Mode: A deeper, energy-efficient dark theme designed for OLED displays.
- Pop-Up View: Enables floating window multitasking for apps like YouTube and Messages.
- 2×2 Quick Setting Tiles: Allows faster access to essential settings with a cleaner layout.
- Custom Lock Screen Clocks: Two new styles inspired by Nothing’s signature typography.
- Essential Apps & Playground Widgets: Lets users create and share custom widgets via the Nothing Playground community.
The update also refines the camera experience for the Nothing Phone 2 series with a new “Stretch” camera mode, previously exclusive to the Nothing Phone 3.
Focus on AI and Privacy
Nothing OS 4.0 continues the company’s shift toward AI-integrated mobile experiences. Under the codename Flow, the update promises smoother system animations, proactive app suggestions, and context-aware notifications.
One of the most talked-about additions is the Lock Glimpse feature — a customizable lock screen module designed to display timely updates, reminders, and contextual insights. However, Nothing confirmed that this feature will be disabled by default on the Phone 3a series following privacy concerns raised during beta testing.
Despite the growing integration of AI tools, Nothing emphasized that user privacy remains central. Sensitive data processing will remain on-device whenever possible, reducing reliance on cloud servers.
Community Feedback and Beta Testing
The company expressed gratitude to its beta testers for their role in refining the update. In a statement posted to the Nothing Community, the brand said:
“We know you’ve been eagerly waiting for the general release and want to say a special thank you to our Beta testers for providing valuable thoughts and feedback. The wait is nearly over.”
The open beta phase, which began in late October, reportedly received strong feedback from users praising smoother animations and faster app launches.
What Comes Next After Nothing OS 4.0
With the nothing os 4.0 stable release, Nothing aims to unify its software ecosystem across multiple devices — from smartphones to CMF accessories. Future updates are expected to expand the AI toolkit and add further customization options.
Insiders suggest that the company is already testing Nothing OS 4.1, a minor follow-up release that could bring additional bug fixes and enhancements in early 2026.
As competition in the Android ecosystem intensifies, Nothing’s clean, design-focused OS has carved out a niche among users seeking simplicity and innovation.
Conclusion
The nothing os 4.0 stable release marks an important milestone for Nothing’s young but ambitious smartphone lineup. With the nothing os 4.0 update release date confirmed for November 21, users can look forward to a blend of sleek design, AI-powered intelligence, and smooth performance.
If you’re a Nothing Phone owner, now is the time to prepare your device for the update and back up your data before installation.
