OnePlus 15 & 15R Start ColorOS 17 Beta in India — What It Means for Users

Last updated: August 2026

OnePlus has officially begun one of the biggest software transitions in its history. The company has opened its first-ever ColorOS 17 Closed Beta Testing (CBT) programme for the OnePlus 15 and OnePlus 15R, and India is the very first market to get it. For millions of OnePlus fans, this is a landmark moment, because it marks the beginning of the brand's long-discussed move away from OxygenOS to ColorOS, the Android skin developed by OPPO.

If you own a OnePlus 15 or 15R, or you are planning to buy one, here is everything you need to know about this ColorOS 17 update in India, what is changing, and what it means for your phone going forward.

ColorOS 17 Beta Goes Live in India First

OnePlus has rolled out a limited closed beta build, based on Android 17, exclusively for the Indian variants of the OnePlus 15 and OnePlus 15R. Interestingly, even though both phones are sold in other regions, this first ColorOS beta is reserved only for India for now. Global, US, and EU models are not part of this initial wave, and OnePlus has not yet confirmed when a wider international rollout will begin.

The programme is genuinely exclusive. OnePlus offered around 300 test slots for each device — 300 for the OnePlus 15 and 300 for the OnePlus 15R. To be considered, interested users had to register within a short application window and successfully pass a qualification quiz. Some applicants may also be asked to sign a non-disclosure agreement before receiving the firmware. Those selected are notified after OnePlus reviews the applications.

The End of OxygenOS: Why the Switch to ColorOS?

For years, OxygenOS was one of the biggest reasons people chose a OnePlus phone. Its clean, near-stock Android feel, smooth performance, and thoughtful features helped OnePlus build a loyal community. So the move to ColorOS is a significant, emotional change for many long-time users.

OnePlus has confirmed that eligible devices will transition to ColorOS starting with the Android 17 generation. The reasoning is largely practical: by combining engineering resources with OPPO and Realme under a single software platform, the company aims to deliver faster and more consistent updates across all its devices. In truth, this change is not as dramatic under the hood as it sounds — OnePlus phones sold in China have run ColorOS for years, and OxygenOS and ColorOS have shared much of the same underlying code for a long time. The main differences are in the interface design and a few regional tweaks.

There is also good news for existing users: the switch is voluntary. Phones currently running OxygenOS will continue to receive regular software and security updates under their existing policies, and users will be given the option to move to ColorOS rather than being forced into it immediately.

What's New in ColorOS 17?

Early beta impressions and leaks point to a refreshed and more polished experience. Some of the highlights reported so far include:

• A refreshed visual design with new lighting and illuminated edge animations
• More blur effects and redesigned rounded UI elements throughout the interface
• Smoother transitions and animations across the system
• Improved performance and CPU resource management for better efficiency
• Greater overall system stability once the software matures

Because this is an early closed beta meant purely for testing, bugs and stability issues are expected. OnePlus and OPPO both advise against installing it on your primary device. If you rely on your OnePlus 15 or 15R every day, it is wiser to wait for the more stable Open Beta or the final public release.

Which OnePlus Devices Will Get ColorOS 17?

While the OnePlus 15 and 15R are leading the beta, the broader ColorOS 17 update is expected to reach a wide range of OnePlus phones and tablets, including the OnePlus Open, OnePlus 13 series, OnePlus 12 series, OnePlus 11, several Nord models, and multiple OnePlus Pad tablets. Devices older than the OnePlus 11, however, are not expected to make the list and will likely remain on their current software with security patches only.

Should You Join the Beta?

If you love exploring the newest software and you have a spare device, the closed beta is an exciting first look at the future of OnePlus. But for most people, patience is the smarter choice. Closed beta builds are unfinished, can drain battery faster, and may cause app compatibility problems. Waiting for the stable rollout ensures you get ColorOS 17 with all its features working smoothly.

Keep Your OnePlus 15 & 15R Protected

Whether you are testing the ColorOS 17 beta or simply enjoying your device on OxygenOS, protecting your phone should always be a priority. A flagship like the OnePlus 15 or 15R deserves proper protection against drops, scratches, and everyday wear. Here are some top picks from Royal Star:
