CMF Phone 1 now receiving Nothing OS 3.0 Open Beta 1 based on Android 15 | Tech Tips

Previously, Nothing started the rollout of the Android 15-based Nothing OS 3.0 open beta to the Phone (2) and Phone (2a). Now, it is being pushed to the CMF Phone 1 (review) that shipped with Android 14 version at launch. The update gives users the chance to expereince Android 15 features. The company has detailed these in an official changelog. The stable build of the Nothing OS 3.0 is expected to be available in the coming weeks. 

Nothing OS 3.0 Open Beta for CMF Phone 1

• The release of the Nothing OS 3.0 Open Beta for CMF Phone 1 was announced on its community forums. 
• Those interested in updating must ensure that their device is running on Nothing OS 2.6 version with the build number Tetris-U2.6-241021-2030 / Tetris-U2.6-241125-2107. 
• There’s an APK file of the open beta in the announcement post on the forum. 
• Users need to install it from the downloads folder and then navigate to Settings > System > Update to Beta version. 
• This will start the update process on the device. 

Nothing cautions users to take a backup of their data as the beta version may interfere with the data and require a factory reset. The brand also warns that there is no rollback option for the CMF Phone 1 once you update to the Nothing OS 3.0 open beta. This means that you can’t return back to a stable OS version.

Nothing says that a rollback package will be released at a later date. Hence, it makes sense to wait for the official stable release of the software instead of installing the beta version on the CMF Phone 1 especially if it’s your daily driver. 

Nothing OS 3.0 open beta features

The Nothing OS 3.0 open beta brings similar features to the CMF Phone 1 as the beta updates for the Phone (2) and Phone (2a). It introduces shared widgets but only for Nothing devices, a revamped lockscreen, and an AI-powered smart drawer. There’s also camera improvements, changes to the quick settings menu, enhanced pop-up view for better multitasking and easier access, new fingerprint and charging animation.
