How to Apply for ColorOS 17 Closed Beta
If your device is on the list, follow these steps:
Open Settings on your phoneNavigate to About Device (or System Update)Tap the three-dot menu in the top-right cornerSelect Beta Program or Trial VersionTap Closed Beta / CBT Recruitment and submit your application
OPPO will review applications, and approved users will receive the closed beta through a special OTA update. Applicants may need to complete a qualification quiz and sign a non-disclosure agreement before receiving the firmware.
Back up your data first. Closed beta builds represent early Android 17 development and are expected to contain bugs, battery drain issues, and app compatibility problems. OPPO advises against installing the beta on a primary device.
What’s New in ColorOS 17?
OPPO hasn’t published a full changelog yet, but early beta information and leaks point to several significant changes.
Visual redesign. ColorOS 17 introduces what OPPO is calling a “liquid acrylic” aesthetic. That means new lighting animations, illuminated edge effects, enhanced background blur elements, a uniform rounded-corner design language across widgets, toggles, and settings panels, and noticeably smoother transitions across the entire system. OPPO Design Director Chen Xi confirmed the update prioritizes performance and stability over flashy visual overhauls, deliberately toning down the glass-like refraction effects so the UI draws less power and keeps text legible, a clear contrast to Apple’s more aggressive Liquid Glass direction.
AI assistant upgrade. The update is expected to introduce Xiaobu Next, a major overhaul of OPPO’s built-in AI assistant. Early reports suggest improved voice interactions, more personalized suggestions, and deeper integration with everyday tasks. ColorOS 17 also reportedly includes AI Photo Unblur, Reflection Removal, and intelligent voice summaries for meetings and calls.
Android 17 core improvements. As a build based on Android 17 (codenamed Cinnamon Bun), the update carries Google’s latest system optimizations, privacy enhancements, and performance improvements. These include better RAM management, reduced background frame drops, and improved battery efficiency.
Why This Beta Matters: OxygenOS and Realme UI Are Gone
The ColorOS 17 closed beta is more than a routine software test. It marks the first time OnePlus and Realme devices are officially running ColorOS rather than their own software platforms.
Both OnePlus and Realme confirmed in July 2026 that OxygenOS and Realme UI are being permanently retired. Every device eligible for Android 17 will transition to ColorOS 17. The move is part of a broader restructuring by parent company BBK Electronics, which aims to consolidate software development across all three brands under a single platform.
For existing users, the transition is voluntary. OnePlus has confirmed that devices running OxygenOS will have the option to switch, and a limited rollback window will be available for users who want to revert. Devices that don’t qualify for Android 17 will continue receiving maintenance updates and security patches under their current software.
The practical upside is clear. Eliminating three redundant software pipelines should mean faster updates, more consistent feature rollouts, and better use of shared engineering resources. Early performance claims include up to 13% better battery life and 3 to 6 degrees Celsius lower gaming temperatures compared to the previous fragmented approach.
Whether users who valued OxygenOS’s cleaner, near-stock Android experience will accept a more feature-dense ColorOS remains an open question. But with the closed beta now live, the transition has officially begun.
FAQsWhen will ColorOS 17 be officially released?
OPPO has not confirmed a stable release date. The closed beta opened on August 6, 2026, with builds rolling out August 11 and 13. The stable version is expected to debut alongside the OPPO Find X10 series in Q4 2026, with a wider rollout to other devices through early 2027.
Is ColorOS 17 available for OnePlus phones?
Yes. OnePlus has confirmed that OxygenOS is being retired and all eligible OnePlus devices will transition to ColorOS 17 with the Android 17 update. The OnePlus 15, 15R, 15T, and Pad 3 Pro are among the first devices included in the closed beta.
Can I go back to OxygenOS after switching to ColorOS 17?
OnePlus has confirmed a limited rollback window for users who upgrade to ColorOS 17 and want to return to OxygenOS. Full details on the rollback process have not been announced yet.
What happened to Realme UI?
Realme UI is being discontinued. Realme confirmed that all future smartphones will run ColorOS, starting with the Android 17 update. The Realme GT 8 Pro is already included in the ColorOS 17 closed beta program.
Will my OPPO mid-range phone get ColorOS 17?
The current closed beta is limited to flagship models. OPPO typically begins with premium devices before expanding to Reno, F, and K series phones. A full eligibility list has not been published, but most devices within their update policy window are expected to qualify for the stable release.
