CMF Phone 1 Updated to Nothing OS 3.2 (September Patch) Ahead of Major OS 4.0 Release

Nothing has released a new OTA update for the CMF Phone 1. This update is based on Nothing OS 3.2 (September patch) and mainly focuses on improving system performance and fixing minor bugs. Even though it’s already October, the company has rolled out the September update for CMF Phone 1 users.

The update size is 63.90 MB, and it installs successfully in about 10 minutes. After installing, users can see the updated build number ending with 18843-ID. The Android security patch is dated September 1, 2025, and matches the latest Google Play system update once updated manually.

What’s New in This Update

1. Photo Widget Improvement:
   The photo widget now fills the full space when resized to a 4×2 format, making it look more complete on the home screen.
2. Media Player Bug Fixes:
   Issues related to album cover and song info display in the media player and widget have been fixed. Users can now see correct song details and album art while using apps like Spotify.
3. System Stability Improvements:
   Overall system stability and smoothness have been slightly optimized, though most users won’t notice a major difference.

Why This Update Matters

This is likely a preparation update before the major Nothing OS 4.0 rollout. Currently, Nothing OS 4.0 has been released for Nothing Phone (2), Phone (2a), Phone (2a) Plus, and Phone (3). However, the CMF Phone 1 and CMF Phone 2 Pro are not part of the open beta program.

According to Nothing’s official community post, both devices will directly receive the stable Nothing OS 4.0 update later, instead of joining the beta phase.

When Will CMF Phone 1 Get Nothing OS 4.0?

Nothing has confirmed that CMF Phone 1 will get the stable Nothing OS 4.0 update at a later date, possibly between November and December 2025. This upcoming update is expected to bring Android 16-based features, design changes, and performance improvements.
