Origin OS is an Android-based operating system by Vivo, a Chinese multinational technology company.

Origin OS 4 (4.0) is based on the Android 14 operating system and adds the "Blue Heart Little V" global intelligent assistance function.

[9] Origin OS 4 also further optimizes response time, UI design, and adds vivo Sans fonts.

It was done with the motive to address the feedback of the users regarding Funtouch OS and to go along with modern trends in Android customization.

[12] The new Origin OS comes pre-installed on the Vivo X60 series, which was one of the first sets of devices to use this new operating system.

The system has been upgraded over time to continue improving its performance, adding more options for user customization, and providing better security, although Origin OS remains only available in China, where it has not yet had an official rollout elsewhere.
