Nothing OS 4.0 Update: Full Feature Breakdown You Need to Know Before Upgrading

Nothing OS 4.0 is now officially rolling out to multiple Nothing phones, bringing a refreshed design, new AI capabilities, deeper customization, and several performance-focused enhancements. The update, based on Android 16, is available for Nothing Phone 2, 2A, 2A Plus, 3A, 3A Pro, and Phone 3, and introduces a noticeable shift in the overall user experience.

One of the biggest visual upgrades comes in the redesigned About Device layout, full-screen device image, new icons, and improved status bar elements. Users also get an updated boot animation and more flexibility in the Quick Settings panel, where nearly all tiles now support adjustable sizing. The Control Center experience feels more refined with new vibration cues and enhanced notification swipe effects.

Nothing OS 4.0 further introduces smarter features like app hiding directly from the home screen or app drawer, upgraded global search, new widget sizes, and AI usage tracking within the Intelligent Toolkit. Users can also take advantage of the newly added flip-to-record gesture and the extra dark mode for a deeper black theme across the interface.

Other additions include new lock-screen clock styles, glyph improvements with calendar progress bar support, camera UI redesign, updated presets, and improved motion photo behavior. Some users may not notice major animation improvements on all devices, but the overall update still brings significant refinements.

Nothing OS 4.0 stands as one of the most feature-packed updates from the brand, offering a mix of visual polish, functional upgrades, and more user control.
