Nothing OS 4.0 Open Beta Update: Exciting New Features You Must Try

1. Introduction

Nothing, the London-based technology company led by Carl Pei, has quickly gained attention in the smartphone world with its unique design philosophy, transparent aesthetics, and close-to-stock Android experience. Since the launch of the Phone (1) and its successor, the Phone (2), Nothing has been building a strong reputation for delivering clean software experiences through Nothing OS. Now, the company is rolling out the much-anticipated Nothing OS 4.0 Open Beta—a major update designed to refine user experience, enhance performance, and introduce several new features.

This update marks an important step in Nothing’s journey toward making its software as iconic as its hardware. Unlike previous incremental updates, Nothing OS 4.0 brings an overhauled interface, optimization for smoother performance, and new personalization tools that help users customize their devices better. The open beta also shows the brand’s commitment to community involvement, as early adopters get to test the update and provide valuable feedback before the stable rollout.

For users curious about what Nothing OS 4.0 offers, how to install it, and whether their device supports it, this article provides a complete breakdown. From step-by-step installation instructions to exploring key features, here’s everything you need to know about the Nothing OS 4.0 Open Beta update.

2. Nothing OS 4.0 Open Beta: How to Install?

Installing the Nothing OS 4.0 Open Beta isn’t complicated, but since it’s still a beta version, users should proceed with caution. Beta updates are primarily intended for tech enthusiasts and testers who don’t mind occasional bugs or glitches. If you rely on your device for day-to-day use, it’s recommended to wait for the stable release.

To install the beta, users need to first ensure that their Nothing phone is updated to the latest stable version of Nothing OS 3.x. Once that’s done, they can register for the beta program through Nothing’s official community portal. After successful enrollment, the update will appear in the Settings > System > System Update section.

Before installing, it’s important to back up your data since beta builds may cause unexpected issues. The update can be downloaded over Wi-Fi and requires sufficient battery life—at least 50%—to avoid interruptions. Installation typically takes about 15–20 minutes, after which the phone will reboot into the new OS.

Nothing also allows users to roll back to the stable version if they encounter issues. However, rolling back erases all user data, so a backup is essential. Overall, the process is user-friendly, and Nothing has provided clear instructions on its official forums for anyone attempting the upgrade.

3. Nothing OS 4.0 Key Features

The highlight of the Nothing OS 4.0 update lies in its new features and optimizations. While Nothing has always focused on simplicity and minimalism, this update builds on that foundation with added functionality and improved efficiency.

One of the biggest upgrades is in performance optimization. The OS now feels faster and smoother, thanks to under-the-hood improvements in memory management and app launching. Users will notice reduced lag, better animations, and improved multitasking.

Another major focus is customization. Nothing OS 4.0 introduces new lock screen options, redesigned widgets, and enhanced theme controls that let users tailor their device’s look and feel. The popular Glyph Interface also receives software-level upgrades, allowing deeper integration with notifications and third-party apps.

Security and privacy have also been enhanced, with more granular permission settings, improved app tracking controls, and better biometric authentication support.

For productivity, Nothing has included smarter quick settings, a redesigned control panel, and new shortcuts for faster access to frequently used features. Battery management has also been improved with AI-based optimization that extends device life without sacrificing performance.

Overall, Nothing OS 4.0 is not just an incremental update—it’s a significant step toward making Nothing phones more competitive with established Android players like Samsung’s One UI and Google’s Pixel Experience.

4. How To Join The Nothing OS 4.0 Beta

Joining the Nothing OS 4.0 Open Beta program is straightforward and designed to encourage community participation. Nothing has built a reputation for being highly community-driven, and the open beta is another way for users to directly contribute to the company’s software development.

To join, users must first head to the official Nothing Community website or forum, where beta registrations are open. After logging in with a Nothing account, eligible phone models can be enrolled in the program. Once registered, users will receive the beta update via OTA (Over-The-Air).

It’s worth noting that open beta versions are experimental. While they give early access to new features, they may contain bugs, incomplete features, or occasional stability issues. That’s why Nothing strongly recommends only tech-savvy users or those who don’t mind troubleshooting install the beta.

Participants are encouraged to share feedback and report bugs through the community forum or in-app feedback tool. This feedback helps Nothing engineers refine the OS before the stable release. By joining the beta, users not only get a sneak peek at upcoming features but also play a role in shaping the final version of Nothing OS 4.0.

5. Nothing OS 4.0 Open Beta: Supported Phones

Since Nothing is still a relatively young company with a limited product lineup, the Nothing OS 4.0 Open Beta is only available for select devices. At present, the update supports the Nothing Phone (1) and the Nothing Phone (2), with the possibility of extending to future models such as the anticipated Phone (3).

The Phone (1), Nothing’s debut device, remains central to the beta program. Despite being over two years old, Nothing continues to provide software support, showing its commitment to long-term updates—a key factor for user trust in the Android ecosystem. The Phone (2), on the other hand, is the company’s current flagship and serves as the primary testing ground for Nothing OS 4.0.

Users of other devices, like the Nothing Ear series or the newly launched CMF products, will not receive this beta, as it is strictly limited to smartphones. However, Nothing may roll out ecosystem-level updates in the future that integrate better with its audio and wearable devices.

If you own a supported phone, you can join the beta right away. If not, the best option is to wait for the official stable release, which will eventually be available for all supported devices globally.

Conclusion

The Nothing OS 4.0 Open Beta Update marks a significant milestone in Nothing’s journey toward creating a clean, efficient, and user-friendly Android experience. With this update, users of the Phone (1) and Phone (2) can enjoy smoother performance, enhanced customization options, and a host of new features that make daily interactions with their devices more intuitive and enjoyable. The improved Glyph Interface, redesigned widgets, and smarter battery management highlight Nothing’s focus on both aesthetics and functionality.
