Nothing OS 4.0 Open Beta: AI-Powered Essential Apps, Supported Phones, and Full Details
The world of technology never stops in its incessant innovations, and now another exciting update has arrived for smartphone lovers. Nothing OS 4.0 Open Beta is finally live, giving users early access to a new generation of AI-powered Essential Apps, design updates, and camera features. If you’re a fan of Nothing, this is a golden opportunity to try the new software, which is based on Android 16.
Nothing OS 4.0 Brings AI-Powered Essential Apps and a New Design
The biggest highlight of Nothing OS 4.0 Open Beta is the Essential Apps suite, which includes AI-powered tools. These apps make your daily phone usage smarter and more convenient. The company has also added new presets within the camera, with the “Stretch” camera preset becoming quite popular. This feature, designed in collaboration with photographer Jordan Hemingway, gives images a distinct depth. Photos will have an artistic feel with rich shadows and bright highlights.
There have also been noticeable enhancements to system and design-level performance with the new update. Users get quicker app switching, cleaner animations, and a generally more responsive feel.
AI Usage Dashboard and Essential Space
Nothing OS 4.0 brings an exclusive feature for iPhone (3) users – the AI Usage Dashboard, integrated within Essential Space. This dashboard aims to provide transparency into how large AI models are working on your phone. Lock screen performance, Always-On Display, brightness controls, and camera stability have also been improved.
The update is also strong on the connectivity front, as both Bluetooth and Wi-Fi performance has now been made more reliable.
Camera, App Optimization, and Dark Mode

The new Stretch Camera Preset is a game-changer for iPhone 2, iPhone 2a, and iPhone 2a Plus users. This preset specifically improves image tones and creates a cinematic feel. A system-level app optimization option has also been added, reducing app startup time. This feature is available in the Settings > Apps > App Optimization section.
Nothing OS 4.0 also includes new lock screen clock styles, a pop-up view with dual floating icons, and 2×2 Quick Settings tiles. For those who use their phones late at night, an “Extra Dark Mode” toggle has been added to reduce eye strain.
Essential Apps and Widget Support
Essential apps have become even more powerful with this update. AI-powered widgets can now be created, which you can share within Playground. Phone 3 users have the option to add six widgets, while Phone 2 and Phone 2a series users are limited to two. This flexibility gives users a personalized and smart experience.
Supported Phones and Availability
Nothing OS 4.0 Open Beta is currently live for select models. This update is available for Phone (3), Phone (2), Phone (2a), and Phone (2a) Plus users. However, an important condition is that your device must be on the latest stable build.
The deadline for Beta OTA enrollment is October 14, 2025. The rollout for the Phone (3a) series will begin at the end of October. However, the company has not yet confirmed when the update will arrive for older Nothing phones or CMF-branded devices.
Rollback Option for Users

If you feel that Nothing OS 4.0 Open Beta is not stable enough for you, the company has also provided a rollback option. This allows you to revert to Nothing OS 3.5. But remember one important point: the rollback process requires a factory reset. This means all data on your phone will be erased, so backing up is mandatory.
Global Rollout and Future Expectations
The company has confirmed via a community forum that this Open Beta rollout is happening globally. No matter where you are, if you use an eligible device, you can try this update. This Open Beta is essentially an exclusive preview that gives users a first taste of Nothing’s latest AI and design vision.
In the future, more optimizations and user-demanded features are expected to be added to the stable version of Nothing OS 4.0. Nothing is already popular for its bold designs and innovative approach, and this update is another strong step in that journey.
Conclusion
Nothing OS 4.0 Open Beta is an exciting step forward, bringing AI-powered Essential Apps, stunning camera presets, design improvements, and powerful customization options. If you are a Nothing user, this update will surely provide you with a smarter and fresh smartphone experience. However, keep in mind that because this is still a beta build, there is a possibility of bugs and glitches. A rollback is possible, but the procedure is through factory reset, so please be sure to back up your files.
