OxygenOS. It is a custom Android firmware developed by OnePlus for its smartphones, first launched in 2015 alongside the OnePlus 2. Designed to offer a clean, fast, and customizable user experience close to stock Android, it has been a defining software feature for the brand. The operating system is known for its performance optimizations, thoughtful additions to the Android Open Source Project, and a distinct visual identity that appeals to technology enthusiasts.

History

The development of the software was initiated by OnePlus following significant user feedback and controversy surrounding its first software offering, ColorOS, which was based on a build from its investor, Oppo. The first stable version was publicly released for the OnePlus One in April 2015, marking a pivotal shift in the company's software strategy. A major turning point occurred in 2021 when OnePlus announced a merger of its codebase with Oppo's ColorOS, fundamentally changing its underlying architecture while aiming to retain its signature user experience. This integration was part of a broader organizational merger between OnePlus and Oppo, both under the umbrella of the BBK Electronics conglomerate.

Features

The interface provides a near-stock Android experience with a high degree of customization through features like a system-wide dark mode, extensive icon pack support, and the Zen Mode focus tool. Performance is emphasized through technologies like RAM Boost and the proprietary Trinity Engine, which optimize resource allocation for gaming and multitasking. Distinctive utilities include the Shelf information panel, advanced gesture navigation options, and the Always-on Display with customizable designs. It also incorporates unique visual elements such as custom wallpapers, font styles, and accent color choices, allowing users to personalize their devices extensively.

Development and updates

The development process is managed by the software team at OnePlus, with major updates historically aligned with new releases of the Android operating system. Following the integration with ColorOS, the development cycle now shares a common codebase with Oppo, streamlining the process for security patches and platform upgrades. The company operates a public beta program for select devices, allowing members of its OnePlus Community to test early builds and provide feedback. Update policies, including the duration of support for Android version upgrades and security patch deliveries, are formally outlined for each device series, such as the OnePlus Nord line and flagship models like the OnePlus 11.

Reception

Initial reviews from publications like Android Authority, XDA Developers, and The Verge praised the software for its speed, clean aesthetics, and useful additions that enhanced stock Android without overwhelming it. This positive reception was a key factor in building a loyal fanbase for OnePlus in markets like North America and Europe. However, following the merger with ColorOS, some critics and long-time users expressed concerns about increased bloatware, a departure from its original minimalist philosophy, and inconsistencies in the user interface. Despite this, it continues to receive generally favorable marks for its performance and feature set in comparative reviews against software from Samsung and Google.

Comparison with other operating systems

When contrasted with Samsung's One UI, it is typically seen as less feature-heavy and more streamlined, though One UI offers deeper integration with the Samsung Galaxy ecosystem and more granular controls. Compared to Google's Pixel software experience, it offers greater customization and more performance-tuning options, whereas the Pixel software is often noted for its simplicity and earliest access to new Android features. Against other Android skins like Xiaomi's MIUI or realme's realme UI, it is frequently regarded as faster and less cluttered with advertisements, though its update policy and feature scope may vary. The underlying merger with ColorOS has also drawn direct comparisons to the software experience on Oppo devices, highlighting shared components while maintaining distinct surface-level designs.
