The beta introduces a wide range of enhancements in performance, design, connectivity, and camera functionality, all built on Android 16.
The update brings AI-powered widgets and new camera presets, allowing users to leverage advanced artificial intelligence for a more personalized and efficient experience. The improvements aim to enhance everyday usability, from smarter notifications to intuitive app management. The design has also been refined to provide a smoother, more visually appealing interface, with tweaks to icons, menus, and animations.
Users participating in the beta can explore performance upgrades, including faster app launches, improved multitasking, and better battery optimization. Connectivity features have been enhanced for stable network performance and seamless device integration, particularly across smart home and IoT ecosystems.
To join the open beta, users must ensure their device is running the latest stable build: Metroid-V3.5 for Phone (3), Pong-V3.2 for Phone (2), and Pacman-V3.2 for Phone (2a and 2a Plus). Interested users must register before October 14, 2025, after which new registrations will no longer be accepted. Nothing advises backing up all data before installing the beta to avoid any potential loss.
This release marks Nothing’s continued commitment to offering early access to cutting-edge features while gathering user feedback to refine the final version. Beta participants will play a key role in identifying bugs, suggesting improvements, and shaping the OS experience before its official global rollout.
With AI integration, improved design, and enhanced camera tools, Nothing OS 4.0 promises to deliver a more immersive and intelligent smartphone experience. The beta is expected to help Nothing gather insights for future updates, ensuring the OS meets user expectations for performance, usability, and innovation.
