OnePlus Is Retiring OxygenOS; ColorOS 17 Will Be Optional on Eligible Existing Devices

OnePlus is phasing out OxygenOS as it moves its phones and tablets to Oppo’s ColorOS platform. The transition starts with ColorOS 17, an interface based on Android 17.

Future OnePlus phones will use ColorOS. Eligible phones already in use can install ColorOS 17 voluntarily, and OnePlus says owners who make the switch will have a way to return to OxygenOS.

Older devices outside the Android 17 upgrade range will remain on OxygenOS under what OnePlus calls “maintenance support.” The company hasn’t said how long that maintenance will last or how often security patches will arrive.

The clearest reported timetable puts the OnePlus 15 and OnePlus Pad 4 first, in late October 2026. Other named phones and tablets are expected to follow through the end of 2026 and into the first quarter of 2027. Dates may differ by region, carrier and device.

There isn’t one worldwide launch date, and precise schedules outside China and India haven’t been provided.

Five OnePlus tablets appear in the rollout material: the Pad 4, Pad 3, Pad 2, Pad Lite and Pad Go 2. Their release windows stretch from late October 2026 through the first quarter of 2027. OnePlus hasn’t detailed which tablet-specific or cross-device features they will gain beyond the shared ColorOS 17 foundation.

The company also hasn’t published a definitive list of every device that will miss the update. Several reports identify older phones expected to remain on OxygenOS, but those conclusions are based on previous update commitments and interpretations of OnePlus policy—not an official model-by-model exclusion notice.

OnePlus’s regional notices say eligible existing devices won’t be required to install ColorOS 17. The company has also promised rollback options for people who update and later want to return to OxygenOS.

The details remain unsettled. Available rollback versions will depend on future announcements, so it isn’t clear which version each model can return to or how long those options will remain available.

The Indian beta offers one concrete example. A rollback package is available for at least the OnePlus 15, allowing testers to return to stable OxygenOS 16. That process erases data stored on the phone.

Owners can choose to stay on OxygenOS, but that isn’t a promise of equivalent long-term support. OnePlus hasn’t published a software or security-support timetable for eligible devices whose owners decline ColorOS 17.

OnePlus opened ColorOS 17 beta recruitment in India for five phones: the OnePlus 15, 15R, 13, 13R and 13s. A beta is an unfinished test version, not the final software. Applications were accepted from October 9 through October 12, a four-day window.

Only eligible Indian phones without carrier locks—restrictions tying a phone to a mobile provider—and running specified OxygenOS 16 versions could join. Stable ColorOS 17 updates are scheduled to arrive later.

OnePlus and independent coverage warn that testers may encounter missing features, incompatible apps, overheating, faster battery drain or other problems. People who skipped the beta avoid those pre-release risks while waiting for the stable version.

ColorOS 17 introduces a visual system OnePlus calls “Living Flow Design.” It uses translucent layers, continuous screen transitions and animations that make controls appear to compress and rebound when touched.

Its AI tools include AI Mind Pilot, which can organise files, rename and format media, and assemble structured documents. Another feature, OSee, uses the camera for tasks such as translation, object recognition and document scanning.

Some AI work happens on the device. More demanding requests may be sent to OnePlus’s Private Computing Cloud, which the company describes as isolated and end-to-end encrypted. That means information may leave the device when cloud-based tools are used, despite the protections OnePlus promises.

OnePlus also says its new rendering system—the software that draws what you see on the screen—can reduce rendering load by up to 30% and memory use for rendering tasks by up to 25% in certain situations.

Those figures come from OnePlus. They haven’t been independently reproduced on OnePlus hardware, and there is no controlled comparison of OxygenOS 16 and ColorOS 17 running on the same phone. The available information therefore doesn’t show that most owners will get better speed, battery life or stability.

OnePlus will no longer launch new devices in North America and Europe. It says existing owners in those markets will continue to receive software updates, security patches, warranty service and after-sales support.

That commitment doesn’t say when ColorOS 17 will reach each device or carrier. It also doesn’t show that updates will be delayed or worse. The effect on regional timing and update quality remains unknown.
