The smartphone market is changing fast, and London tech firm Nothing has made a name for itself with clean software, daring designs, and a serious community-driven ethos. The firm is now preparing for one of its most massive software launches ever—Nothing OS 4.0, which will be powered by Android 16.
With an emphasis on AI integration, smoother operation, and greater control in the users’ hands, Nothing OS 4.0 is not simply an update—it’s the company’s way of laying down the tone for its future devices. Here’s an in-depth look at all we currently know about this future upgrade, from its features and rollout schedule to which phones are set to be upgraded.
What is Nothing OS 4.0?
Nothing OS 4.0 is Nothing’s next-gen operating system, based on Google’s Android 16. As opposed to most Android skins that encumber the experience, Nothing has always sought a clean, near-stock interface with a dash of its own personality: the dot-matrix design language and Glyph Interface integration.
With OS 4.0, the firm is taking it a step further, introducing more intelligent AI-powered tools, improved personalization features, and increased transparency. The update is aimed at bridging functionality and user control, providing a reason for fans to continue using the Nothing ecosystem.
Notable Features of Nothing OS 4.0
Although the company hasn’t disclosed all the details yet, the official announcements and leaks identify some significant improvements:
1. AI-Centric Improvements
- Nothing OS 4.0 will bring smarter AI behavior throughout the system.
- People will receive AI status indicators, context-aware hints, and an AI usage dashboard to monitor AI usage so they can always know when AI is being utilized and how.
- This strategy brings greater transparency and helps instill confidence in a world where AI surrounds us.
2. Improved Camera and Gallery
- Camera and Gallery apps will experience a significant overhaul.
- Anticipate quicker processing, improved low-light images, and smart photo categorization.
- The priority is to have a photography experience feel smooth while making editing and organizing tasks easy.
3. Enhanced Lock Screen & Always-On Display
- Nothing OS 4.0 will provide users with additional lock screen customization with new clock designs, widget support, and interactive elements.
- The Always-On Display (AOD) will be improved to display smarter notifications without using more battery.
4. Smoother Performance and Stability
- Under-hood optimizations will make apps launch quicker and cut down on background power consumption.
- Based on Android 16, Nothing OS 4.0 will also feature enhanced multitasking and improved memory management.
5. Privacy & Transparency Enhancements
- AI usage dashboards not only track AI but also provide users with the choice to limit or enable specific functionalities.
- Increased emphasis on user privacy is a response to increased demand for control over personal data.
Release Timeline
- Nothing has officially announced that OS 4.0 will start rolling out in autumn 2025, which usually translates to September or November.
- The Nothing Phone (3) will be the first to get the update.
- Subsequently, the release will progressively roll out to the other eligible devices.
- The staggered release allows Nothing to work out kinks before there’s widespread usage and provides its flagship device with an early software advantage.
Eligible Devices for Nothing OS 4.0
According to official news and leaks, here’s the list of devices that are going to get Nothing OS 4.0:
- Nothing Phone (3)—First in line
- Nothing Phone (3a)
- Nothing Phone (3a) Pro
- Nothing Phone (2)
- Nothing Phone (2a)
- CMF Phone 1
- CMF Phone 2 Pro
Not Eligible: The initial Nothing Phone (1) does not appear likely to get the update. Although it got updated with OS 3.x versions, apparently, the hardware constraints or the firm’s software policy in the longer term could be the reason for non-eligibility.
Why Nothing OS 4.0 Matters
Unlike most Android skins that attempt to be flashy but turn out bloated, Nothing OS 4.0 adheres to the philosophy of minimalism and utility pursued by the company. But with the addition of AI-based features and transparency dashboards, the update marks a middle ground between high-tech smart tools and user empowerment.
Here’s why it matters:
- AI with Transparency: The majority of Android skins implement AI without explaining to users how it functions. Nothing OS 4.0 is bringing AI into the open and within users’ control.
- Consistency Across Ecosystem: As Nothing ventures into earbuds, smartwatches, and even CMF sub-brand hardware, OS 4.0 will serve as a common software layer.
- Future-Proofing Devices: Android 16 promises significant performance and security updates, which Nothing OS 4.0 will utilize.
Should You Upgrade to a Nothing Device for OS 4.0?
If you currently have a Phone (2), Phone (2a), or later, the upgrade will be automatic and free when it launches. But if you’re still clinging to the Phone (1), you might feel left behind.
For anyone looking to upgrade, the Phone (3) is going to be the optimal means to enjoy Nothing OS 4.0 in all its glory. Initial rumors indicate that it will release with OS 4.0 pre-installed, which means it will be the most future-proof Nothing phone to date.
Final Thoughts
Nothing OS 4.0 is a daring leap for the company, combining clean design, robust AI utilities, and transparency in one offering. The release is not about cosmetic changes but about making users feel secure in the operation of their device in an AI-focused world.
With a rollout expected in Autumn 2025 and a clear list of eligible devices, the countdown has already begun. Whether you’re already a Nothing user or considering joining the ecosystem, OS 4.0 is shaping up to be one of the most exciting Android-based updates of the year.
