Oppo has initiated ColorOS 17 Closed Beta Testing (CBT) for select Oppo, OnePlus, and Realme devices. This follows Realme's confirmation that all future phones will use ColorOS, and OnePlus's ongoing support for the OS. The global CBT application window opens on August 6-7, with a limit of 300 slots per device. Eligible models include the OnePlus 15, OnePlus 15R, Oppo Find X9 Pro, Oppo Reno 15 Pro, and Realme GT 8 Pro. Participants must back up data due to instability risks. Applications are processed via Settings > Beta Program > Closed Beta Recruitment.

The move aligns with Android 17 Beta for Pixel devices, prompting manufacturers to roll out their own OS updates. Users seeking early access to ColorOS 17 must act quickly, as slots are limited. Devices must be live in specified regions to qualify.

Oppo’s CBT emphasizes testing stability and features before a full release. The program excludes broader users, targeting tech-savvy individuals. Slot availability varies by device and region, requiring immediate registration.

This initiative highlights ColorOS 17's expansion beyond Oppo, integrating OnePlus and Realme ecosystems. The short application window underscores urgency for participants.
