Nothing has begun rolling out Nothing OS 4.0, its latest operating system based on Android 16. Here is a clear breakdown of all the new changes in this update.
Nothing OS 4.0 updates the entire visual layout. First-party app icons now have a cleaner and more minimal look. Status bar icons for Wi Fi, battery and data follow a more consistent style that is easier to read. The lock screen gets refreshed fonts along with two new clock faces. System animations have been reworked so gestures, transitions and the Notification Shade feel faster and more stable. The update also adds light haptic feedback when you reach the maximum or minimum volume.
The new version adds features that aim to cut distractions and improve daily flow. Glyph Progress now supports rides, deliveries and timers across the screen and the Glyph Interface. Because it is built on Android 16, it is no longer limited to specific partners and will support more apps that use the progress feature. Pop up View has been refined to support two floating apps at once, with simple gesture switching. Extra Dark Mode offers deeper blacks, better contrast and lower battery use in low light.
Apps can now be hidden in the App Drawer without moving them to a Private Space. Weather, Pedometer and Screen Time widgets now come in new 1×1 and 2×1 sizes. A new System and Apps Dashboard shows which apps are running in the background and lets you optimise performance with one tap. Universal Search gains filters so you can narrow results more quickly.
Nothing OS 4.0 also introduces Playground. It lets you create your own widgets by chatting with AI, with no coding required. A new Widget Drawer keeps all your widgets in one place so you can organise and access them easily.
The update improves AI transparency. AI Status Hints show when an LLM is active in the status bar. The AI Usage Dashboard shows how AI features are being used across the system.
