The end of OxygenOS is no longer just an announcement. OnePlus has started pushing the stable ColorOS 17 update, based on Android 17, to the OnePlus 15 and OnePlus Pad 4. The rollout began in India in batches, with the OnePlus 15 build carrying the number CPH2745_17.0.0.102(EX01). It is the first time a OnePlus flagship has moved from its own software brand to OPPO's ColorOS through a regular over-the-air update.
The timing is also unusual in a good way. OnePlus' official schedule listed October 29 for the first wave, so the update arrived almost a week early. OnePlus hasn't said yet when owners outside India will get the stable build.
Why OxygenOS is going away
The switch follows OnePlus' decision in July to shut down most of its global operations. At the time, the company promised that existing phones would keep receiving updates for their full support period, but on ColorOS instead of OxygenOS. In practice, the two systems have shared the same code base for years, so the change is more about branding than a completely new experience. Still, ColorOS 17 brings a visual redesign and a long list of AI features, so it will feel fresh on day one.
What's new in ColorOS 17
- Fluid design: new animations and responsive light effects driven by a new Luminous Rendering Engine, plus a redesigned Lock screen, Quick Settings and notification drawer.
- Laminar Flow Engine: smarter memory scheduling meant to reduce lag when RAM is full and keep the apps you actually use alive in the background.
- Mind Pilot Agent mode: an AI assistant mode that can handle multi-step jobs like organising photos and files, making collages or producing reports.
- OSee: AI vision tools including document scanning with layout-aware text extraction and PDF export.
- New Translate app: photo, voice and text translation in one place, with lower-latency real-time translation.
- Security: AI face-swap detection in video calls and detection of AI-generated voices in scam calls.
- Audio: an option to play sound from several apps at the same time.
Which OnePlus devices are next
OnePlus has published a schedule covering 24 devices. After the OnePlus 15 and Pad 4, the OnePlus 15R, OnePlus 13 and OnePlus 13s are due on October 30. November is planned for the OnePlus Open, 13R, 12, Nord 6, Nord CE6 and Pad 3. December covers the OnePlus 12R, OnePlus 11, Nord 5, Nord CE5, Nord CE6 Lite, Pad 2 and Pad Go 2, and the remaining models, including the Nord 4 and N6 family, follow in the first quarter of 2027.
Early feedback
Reaction on the OnePlus Community forum is mostly positive, but not entirely. Some OnePlus 15 owners say the AI photo-editing agent they expected isn't in their build yet, and other forum members believe it will come in a later update. One user also complained that photos edited with AI tools now get an "AI" label, although others replied that it can be switched off. If the update causes serious problems, OnePlus does offer a rollback package to the previous OxygenOS version, but it wipes the device, so back up before updating.
Our take
For OnePlus owners, this update is less dramatic than the headlines suggest. The software was already close to ColorOS, and the company is keeping its update promises after leaving most markets. That is the most important part: a phone that keeps getting Android versions and security patches is still a good phone. The real test will be the global rollout. Owners in Europe and North America will want to see that OnePlus keeps the same early pace there and that missing features like the photo agent actually arrive.
