New Delhi, October 25, 2025:
Nothing Technology has officially rolled out the Nothing OS 4.0 Open Beta for its Phone (3a) series, built on Android 16. This beta release offers early access to revamped visuals, new features, and performance enhancements, giving users a first look at the next-generation experience of Nothing’s unique operating system.
Key Features of Nothing OS 4.0 on Phone (3a)
The Open Beta introduces several distinctive Nothing-centric features alongside the core Android 16 improvements:
1. Refreshed Visuals and Icons
Nothing OS 4.0 brings a complete visual overhaul with new, lighter iconography and a refined interface. The update maintains the brand’s minimalist aesthetic while offering a cohesive, modern look across apps and system menus.
2. Lock Glimpse: A Smarter Lock Screen
The new Lock Glimpse feature delivers curated wallpapers and useful content directly on the lock screen. Users can toggle the feature on or off and customize it with personal photos in future updates. It provides glanceable information similar to Android’s “At a Glance” widgets, enhancing both utility and aesthetics.
3. “Stretch” Camera Preset
Photography enthusiasts can now explore the Stretch Camera preset, developed with photographer Jordan Hemingway. This preset enhances deep shadows and extended highlights for a cinematic effect directly in the Camera app, giving photos a professional, artistic look without post-editing.
What Android 16 Brings to Nothing OS 4.0
The beta is built on Android 16, which introduces:
- Live Updates: Real-time notifications for ongoing activities like deliveries or ride-hailing.
- Notification Cooldown: Reduces alert volume when multiple notifications arrive at once.
- Enhanced Accessibility: Improved hearing aid integration and clearer call experience in noisy environments.
- Advanced Protection Mode: Google’s strongest security measures to safeguard against malware and online threats.
