Key Features and Changes in Nothing OS 4.0
1. App Optimization
A new App Optimization feature automatically improves app startup speed and background performance. When enabled, the phone optimizes installed apps one by one. While this process may slightly heat up the device, it ensures smoother app launches.
2. New Pop-Up View for Multitasking
The pop-up view now supports two floating app icons, making it easier to switch between minimized apps. For example, users can quickly toggle between Twitter and Spotify with simple swipes.
3. Lock Screen Customization
Two new clock styles have been added to the lock screen. One is bold and clear, while the other uses a thinner font. This expands customization beyond the previous six clock faces.
4. Quick Settings Improvements
Quick Settings tiles now support a 2×2 square format, allowing larger tiles for easier access.
Other improvements include:
- New animations when toggling flashlight or Glyph Torch.
- Redesigned disable icons with red highlights.
- Swipe up/down to switch Bluetooth devices instead of left/right swipes.
- A direct Share button for Wi-Fi and Bluetooth, making QR sharing faster.
5. Extra Dark Mode
An Extra Dark Mode option is now available, providing deeper black shades for OLED screens. This is especially visible in system menus and About Phone pages. However, it is not fully implemented across all areas, such as Quick Settings.
6. AI Usage Dashboard
Nothing has added an AI Usage Dashboard inside the Intelligence Toolkit. It shows how often AI tools are used, including Essential Apps and Gemini integration.
- Currently, this feature is mainly supported on Phone (3) and upcoming Phone (3a) series.
- It displays usage statistics by day or week, along with model details.
7. Camera Improvements
- New Camera Preset: A “Stretch” filter created in collaboration with photographer Jordan Hemingway has been added.
- Users can also import or create custom presets for unique photo styles.
- General camera stability has been improved for smoother shooting.
8. Essential Apps and Playground
One of the biggest highlights is Nothing Playground, a platform where users can:
- Create their own Essential Apps (widgets).
- Use community-created widgets like calculators, clocks, or even fun tools like Tic-Tac-Toe.
- Explore Camera Presets, Glyph Toys, and EQ Profiles made by other users.
This makes customization more powerful, giving every Nothing user a chance to add unique tools to their phone.
General System Improvements
Apart from new features, the update also brings:
- Always-On Display optimizations
- Better screen brightness control in different scenarios
- Enhanced Bluetooth stability and compatibility
- Improved Wi-Fi connectivity
- System stability and performance boosts
Benchmark results show smoother performance, though major visual changes are limited.
Availability for Other Devices
Currently, the update is live for Phone (3), Phone (2), Phone (2a), and Phone (2a) Plus. The Phone (3a) and 3a Pro series will receive their open beta in October 2025 with additional exciting features.
Should You Update?
The Nothing OS 4.0 Open Beta brings several useful features like app optimization, AI tools, lock screen customization, and dark mode improvements. However, it is not a massive redesign. Features like blur effects or major animation upgrades are still missing.
For regular users, it’s better to wait for the stable release. But if you enjoy testing new software and don’t mind small bugs, the beta version is worth trying.
This update shows that Nothing is focusing on AI, customization, and community-driven features, making their phones stand out in the Android ecosystem.
