OnePlus's Android Lollipop-based ROM, OxygenOS, is available to download now
A little later than expected, OnePlus has finally launched its much-anticipated Android Lollipop-based operating system, OxygenOS, for its One smartphone. — The China-based mobile phone manufacturer …
Context & Ripple Effects
OnePlus has been walking away from its dependency on Cyanogen all year: it shipped an alpha Lollipop build built without Cyanogen in January, then promised to detail the finished 'Oxygen' ROM at a February 12 event. Today's release is the payoff — a downloadable, Lollipop-based operating system for the OnePlus One that the company owns outright.
The timing matters because the One is getting two competing Lollipop paths at once: alongside OxygenOS, the device has begun receiving the official Cyanogen 12 update. That puts OnePlus's own software head-to-head with its former partner's on the same hardware, six years before OxygenOS would be folded into Oppo's codebase in the OxygenOS–ColorOS merger.
First-order effects
- OnePlus One owners can now choose between OxygenOS and Cyanogen 12 on the same device — two rival Lollipop builds from a vendor and its ex-partner.
- OnePlus gains direct control of its software stack, ending the arrangement where its flagship phone's updates flowed through Cyanogen.
Second-order effects
- Cyanogen loses exclusivity leverage over its most famous hardware partner, weakening the third-party-ROM-as-differentiation model it sold to OEMs.
- A split user base forces OnePlus to maintain two update tracks — its own ROM and Cyanogen's — raising support costs but giving enthusiasts a reason to stay in its ecosystem.
Third-order effects
- If the pattern holds, custom-Android startups drift from licensing third-party ROMs to building in-house software that ultimately consolidates under a parent company — exactly where this lineage landed when OxygenOS merged into Oppo's ColorOS while keeping the global OnePlus brand.
- Software control becomes a prerequisite for long update commitments: only an owned codebase let OnePlus later promise three years of Android updates.
The trend: Phone makers are replacing licensed third-party Android ROMs with in-house software stacks that later consolidate under parent-company codebases, as OnePlus's move from Cyanogen to OxygenOS foreshadowed the eventual ColorOS merger.
