ColorOS 17 beta: check the window first.

Verified notices, with their original scope

These are examples rather than a complete beta list. OPPO’s official roundup also lists Find X9 Ultra, X9 Pro, X9s, X9, X8 Pro and X8 for India, Indonesia and Malaysia; the Reno15 pair is limited to India and Malaysia. Those advertised windows were also 9–12 October.

This table records published notices, not a live test of the signup screen on a handset. A new recruitment round would need its own current notice. It should not be inferred from an old article remaining online.

Application, approval and installation

The OnePlus 15 notice directs eligible users to the beta menu under Settings → About device → Up to date. It requires specified existing builds, and approval is followed by OTA delivery. Those conditions belong to that model and recruitment round; they are not instructions to enroll every OnePlus or OPPO phone today.

If you applied during the window, keep the application status and your current build number available when checking the original thread. If you did not apply, use the official-version timeline or look for a genuinely new manufacturer notice.

Decide whether testing suits your phone

A beta is intended for people willing to investigate problems and provide useful feedback. Before choosing one, identify the apps you cannot afford to lose access to, make a current backup, and understand the model-specific return path. Do not experiment on the assumption that all features are finished or that a downgrade preserves your data.

The official 13R notice warns that rollback clears data; its rollback package was marked TBD when checked. A missing package is not a reason to substitute a download intended for another model.

Developer preview is a separate program

The OPPO Android 17 Developer Preview has its own supported devices and instructions. It should not be presented as a universal ColorOS 17 stable update. For ordinary update checks, use the download and OTA guide.
