The British brand Nothing is back with a new OS based on Android 16, named Nothing OS 4.0, which will debut on the Nothing Phone 3. The confirmed rollout schedule for older models has yet to be announced, but Nothing and CMF-branded smartphones will receive the update in the coming days, starting with the Nothing Phone 3a and Phone 3a Pro, which were released this year.
Nothing is also preparing to launch the Phone 3a Lite in India. The global version, which arrived on October 29, ships with Nothing OS 3.5, but the Indian model may include Nothing OS 4.0 right out of the box.
The new update introduces several exclusive features with a strong focus on enhancing the Glyph Matrix display on the back of the device. New additions include Flip to Glyph options and fresh Glyph Toys such as Hourglass and Lunar Cycle. The Glyph Mirror selfie feature has also been updated to save the original image as an additional file in the gallery.
The update also brings the ability to create custom Essential Apps within the Nothing Playground widget builder using AI.
Nothing has added a Glyph Progress feature that uses Android’s Live Updates system to display real-time information for rides, deliveries, and timers directly on the Glyph interface. According to the company, any app that supports Android 16 Live Updates will automatically work with the new Glyph implementation.
Essential Space now features an upgraded AI activity dashboard, providing a clearer view of how larger on-device AI models operate, giving users better transparency.
Nothing OS 4.0 also introduces Essential Apps, lightweight AI-powered widgets that users can create and share through the Nothing Playground platform. Using the widget builder, users can simply describe the type of tool they want, and the AI will generate it automatically.
App Optimization Tools
The update includes a new app optimization system that lets users influence how apps launch and function in the background. By managing resources more intelligently, this feature helps apps open faster and improves multitasking performance.
Photography Updates
A notable camera addition in Nothing OS 4.0 is a new “Sketch” preset developed with fashion photographer Jordan Hemingway. It offers a distinctive visual style within the camera app, enhancing shadows, boosting highlights, and giving images a more cinematic look.
