In a smartphone market that often feels like a sea of identical black rectangles, Nothing has always staked its reputation on being different. With the rollout of Nothing OS 4.0, officially starting on November 21, 2025, for the Phone 3, the London-based company is doubling down on that philosophy. The update, built on the fresh foundation of Android 16, doesn’t just tweak menus or change fonts—it fundamentally changes how you interact with the back of your device.

The headline feature here is Nothing’s spin on Google’s Live Updates. If you’ve ever anxiously unlocked your phone every thirty seconds to check if your Uber has arrived or if your pizza is still in the “prepping” stage, this feature is designed for you. On the new Phone 3, these updates are no longer confined to the lock screen; they live on the device’s “Glyph Matrix”—a retro-futuristic dot-matrix display embedded in the rear glass.

According to details from the launch, the implementation varies depending on which handset you’re holding. On Phone 3, the dot-matrix display visualizes progress with granular animations—imagine a pixelated bar filling up as your ride gets closer. For users of the Phone 3A and older models (like the Phone 2 series), which rely on the standard LED strip “Glyph Interface,” the system is simpler but equally functional: a light strip gradually fills up to mirror the progress of your delivery or timer.

AI that builds widgets for you

Beyond the flashing lights, Nothing OS 4.0 is leaning heavily into the industry’s current obsession: Generative AI. But rather than just adding a chatbot to the home screen, Nothing is introducing the Essentials App.

This new tool allows users to generate custom widgets simply by typing a description. In a demo described by Android Police, a user could type “track my hydration,” and the OS generates a simple, functional widget for that specific purpose. It’s a nod to the “minimalist phone” trend, reducing the need to open full, distracting apps for simple tasks. These widgets can be shared via the “Nothing Playground,” a community hub where users can remix and download each other’s creations.

Multitasking and “Extra Dark” mode

For power users, the update brings a significant boost to multitasking. You can now run two floating apps simultaneously—a feature likely borrowed from the desktop-like ambitions of modern Android. Navigating these windows is gesture-based: swipe up from the bottom to minimize a window into a bubble, or swipe down to expand it back to full screen.

Visually, the OS is getting tighter. Nothing has introduced an “Extra Dark Mode,” which offers deeper blacks than the standard dark mode, ideal for OLED screens and battery saving. This is paired with new lock screen clock faces and updated system animations that Nothing claims offer “sharper tactility,” making swipes and taps feel more responsive.

Phone 3 exclusives: toys and pocket mode

The flagship Phone 3 gets a few exclusive toys to play with—literally. The update introduces “Glyph Toys” for the dot-matrix display. Users can now display an animated hourglass for timers or even track the real-time position of the Moon.

More practically, the Phone 3 now includes a “Pocket Mode.” By utilizing proximity sensors, the phone detects when it’s stashed in a pocket or bag and automatically kills the Glyph Matrix to prevent accidental touches and battery drain—a much-requested fix for a phone that has a screen on its back.

When can you get it?

The rollout is staggered, a common practice to ensure stability.

• Nothing Phone 3: Receiving the update starting November 21, 2025.
• Phone 3A / Phone 2 series: Slated for “the coming weeks.”
• CMF devices: Scheduled to receive the update before the end of 2025.
• Nothing Phone 3A Lite: Users of the budget-friendly model will have to wait until early 2026.

This update solidifies Nothing’s strategy: hardware and software that feels playful and distinct. While major players like Samsung and Google focus on AI photo editing, Nothing is using AI and Android 16 to make the phone itself feel more alive—even when it’s face down on the table.
