CMF has initiated the official rollout of its latest software, Nothing OS 4.0, delivering a significant upgrade to its smartphone users. This major update is now being distributed in phases, starting with owners of the CMF Phone 1. Users of the newer CMF Phone 2 Pro can expect to receive the update in early January, marking a substantial software advancement for both devices.
A Polished Interface and Android 16 Foundation
Built on the latest Android 16 platform, Nothing OS 4.0 focuses on refining the user experience rather than a complete overhaul. The interface has been cleaned up for a more balanced and intuitive feel. Users will notice refreshed system icons, redesigned status indicators, and a simplified Quick Settings layout. These changes are designed to make daily interactions with the phone calmer and clearer.
The update represents a key Android version jump, moving CMF devices from Android 15 to Android 16. This foundational shift brings with it the latest security patches, performance optimizations, and platform-level enhancements from Google, ensuring devices are more secure and efficient.
Enhanced Features: Dark Mode, Customization, and Multitasking
One of the headline features is the improved Extra Dark Mode. This isn't just a simple dark theme; it deepens blacks, boosts contrast for better readability, and helps reduce power consumption. The enhanced mode now works seamlessly across notifications, the Quick Settings panel, the app drawer, and even first-party apps like Essential Space.
For users who love to personalize their home screens, Nothing OS 4.0 introduces new widget sizes. The addition of compact 1×1 and 2×1 formats for apps such as Weather, Pedometer, and Screen Time allows for creating information-rich yet tidy home screen layouts.
Smoother Performance and Smarter Functionality
Multitasking receives a smart upgrade with improved pop-up view functionality. Running two apps in floating windows is now more fluid, with easy switching possible through simple swipe gestures. A new hidden apps feature also provides privacy, letting users keep selected applications out of the main app drawer while retaining quick access when needed.
The overall feel of the OS is smoother thanks to refined system animations. Transitions are more fluid, gestures feel more responsive, and a sense of visual depth has been added. Even small details, like subtle background scaling when opening or closing apps, contribute to a more connected experience. Haptic feedback has also been tuned, with gentle vibrations now accompanying minimum and maximum volume adjustments for better tactile awareness.
The rollout is being conducted in stages via Over-The-Air (OTA) updates. CMF Phone 1 users are first in line, with the CMF Phone 2 Pro following suit in the first part of January 2025. Users should watch for a notification about the update arriving automatically on their devices in the coming days.
