CMF by Nothing has officially started rolling out Nothing OS 4.0 to users of CMF Phone 1 and CMF Phone 2 Pro in India. The update marks a significant milestone for the sub-brand, aligning its budget-focused devices with Nothing’s latest software vision and feature set.

🤖 Android 15 Foundation With AI-Centric Features

Nothing OS 4.0 is built on Android 15, introducing deeper system intelligence and performance optimizations. CMF users can expect smoother multitasking, better memory management, and enhanced background app control. AI-driven improvements aim to make everyday interactions faster and more intuitive.

🎨 Refined Design and Customization Options

The update continues Nothing’s signature minimalist design language while refining animations, transitions, and UI responsiveness. Users gain access to improved lock screen customization, new widgets, and subtle visual tweaks that enhance usability without cluttering the interface.

🔔 Smarter Notifications and Privacy Controls

Nothing OS 4.0 brings upgraded notification handling, allowing users to better prioritize alerts and reduce distractions. Enhanced privacy dashboards give clearer insights into app permissions, while Android 15 security upgrades improve overall data protection.

⚙️ Performance, Battery, and Stability Improvements

CMF says the update focuses heavily on real-world performance. Users should notice improved battery efficiency, reduced thermal throttling during extended use, and increased system stability—especially during gaming and media consumption on both Phone 1 and Phone 2 Pro.

📱 India-First Rollout Strategy

The rollout is being conducted in phases across India, meaning some users may receive the update earlier than others. CMF recommends keeping devices connected to Wi-Fi and ensuring sufficient battery charge before installing the update.
