The Nothing OS 4.1 update, based on Android 16, is now rolling out to both the CMF Phone 1 and CMF Phone 2 Pro. If you are using CMF devices, this update might look small on paper, but it quietly changes how your phone feels every day. This update brings a mix of visual polish, smarter interactions, and stability upgrades. While flagship models get advanced AI features, the update for CMF devices focuses on core performance, camera stability, and refined lock screen customizations, such as the 3a Community Edition clock face.
The update was scheduled for late April 2026, following the release of the Nothing Phone (3) and (3a) series. Let’s break down what actually matters.
Update Size & Rollout Details
- CMF Phone 1 -> 158MB
- CMF Phone 2 Pro -> 165MB
This update is relatively lightweight, so you do not need to worry about large downloads or lengthy installation times.
Nothing OS 4.1 Update Features
One of the unique features is the new lock screen clock, inspired by the Phone (3a) Community Edition. It is designed with a distinctive typeface and features a subtle “wake-up” animation, which imparts a more personal and expressive sensation to your phone each time you use it.
Nothing is giving its version a real-time notification further. With OS 4.1:
- Live Updates now appear across:
- Always-On Display (AOD)
- Notification panel
- Status bar
This indicates that you can monitor aspects such as navigation progress (for example, from Google Maps) without opening applications repeatedly. Some advanced implementations of Live Updates might still face restrictions on CMF devices, depending on the support of the application and the geographical region.
Speaking about surprise addition, it comes with new games app update such as tap-to-play mini games, quick stress relief without downloads, and easy access from home screen or app drawer. It’s not meant for hardcore gaming, but it adds a casual, playful side to the OS that most brands ignore.
OS 4.1 focuses on fixing everyday problems, such as improved camera stability (fewer crashes, better consistency), better wired charging compatibility (especially with some car systems), fixed notification panel & Quick Settings display bugs, enhanced overall system performance, and updated to the April 2026 security patch.
What’s Missing in This Update for CMF Phones?
Early reports and user feedback suggest that some high-end features are not available in the Nothing CMF Phones, such as:
- Advanced Essential Voice features
- Full AI-powered Essential Notifications
- Complete Live Updates ecosystem
What does this update really mean for CMF Users?
Nothing OS 4.1 is not trying to improve your CMF phones; instead, it focuses on:
- Making the UI cleaner and more consistent
- Fixing annoying bugs you actually notice
- Adding small but thoughtful features
If you all care about smooth performance, fewer bugs, and a polished daily life experience, this is exactly the kind of update you all want.
