Updated October 10, 2026: OnePlus has opened ColorOS 17 Open Beta applications in India for five phones: the OnePlus 15, 15R, 13, 13R and 13s. Registration runs October 9–12, 2026. Each phone needs a specified OxygenOS 16 firmware build, and approval is not guaranteed. The most important precaution: although the beta update itself is not intended to wipe data, rolling back to stable OxygenOS 16 will erase the device.
This guide separates OnePlus’s official participation requirements from independently reported details and explains when waiting for a stable update is the better decision. The announced global ColorOS 17 presentation on October 13 is not a confirmed stable-update release date for every Indian OnePlus model.
Key facts at a glance
- Who can apply: eligible Indian variants of OnePlus 15, 15R, 13, 13R and 13s.
- Application dates: October 9 through October 12, 2026.
- How: Settings → About device → Up to date → top-right menu → Beta program.
- Requirements: correct listed firmware, more than 30% battery and at least 4GB free storage.
- What happens next: accepted applicants receive an OTA offer; registration is not the same as receiving the update.
- Major risk: a manual return to OxygenOS 16 wipes user data; check whether your exact model has a valid official rollback package before joining.
Which OnePlus phones qualify for ColorOS 17 Open Beta in India?
OnePlus’s October 9 community notices identify five participating models. Eligibility is narrower than owning the right marketing name: the device variant and installed firmware string must match. The build numbers below are transcribed from the manufacturer announcements where accessible and cross-checked against FoneArena’s October 9 report. These are prerequisite OxygenOS 16 builds, not the future ColorOS 17 beta build numbers.
| India-market OnePlus model | Required OxygenOS 16 build(s) |
|---|---|
| OnePlus 15 | CPH2745_16.0.10.500(EX01)CPH2745_16.0.10.601(EX01) |
| OnePlus 15R | CPH2767_16.0.10.500(EX01)CPH2767_16.0.10.600(EX01) |
| OnePlus 13 | CPH2649_16.0.10.501(EX01)CPH2649_16.0.10.600(EX01) |
| OnePlus 13R | CPH2691_16.0.10.500(EX01)CPH2691_16.0.10.600(EX01) |
| OnePlus 13s | CPH2723_16.0.10.500(EX01) |
For example, an Indian OnePlus 15 on CPH2745_16.0.10.601(EX01) matches a listed prerequisite, but that alone does not guarantee a place. A similarly named model purchased in another market can have a different model code or firmware branch and should not be treated as eligible without its own official notice. Carrier-locked versions are excluded under the published program conditions.
How to apply for the beta before October 12
- Confirm the model and software version. Open Settings → About device and compare the complete firmware string with the table above. If necessary, install an official stable update offered for your exact region; do not sideload a package intended for another variant.
- Make a current backup. Include photos, documents, messages, authenticator recovery information and any app-specific exports. Check that you can actually restore the backup.
- Open the registration screen. Go to Settings → About device → Up to date, then open the top-right menu and select Beta program.
- Review the terms and submit. Follow the on-screen prompts during the October 9–12 window. OnePlus decides who is accepted; application does not mean immediate access.
- Install only after approval. The OTA becomes available in Settings → About device; choose Download Now when the approved update appears. Keep the phone charged and connected to a reliable network.
If the beta option is missing, first verify the model, region, exact firmware and application dates. A missing menu does not prove that all OnePlus 13 or 15 phones are excluded worldwide; this announcement is explicitly India-specific. Do not follow random unofficial download links claiming to bypass enrollment.
What changes when moving from OxygenOS 16 to ColorOS 17?
For the participating devices, the beta is an early opportunity to evaluate OnePlus’s move to the ColorOS 17 software experience. The larger ColorOS 17 feature announcement and China rollout describes the software direction, but features demonstrated for China or at launch should not be assumed present in this first India beta. OnePlus explicitly warns that planned functionality may be incomplete or unavailable in initial builds.
OnePlus and OPPO have shared substantial software technology for years; that background does not make an early beta as dependable as a production release. For owners of the OnePlus 15, this is a software change rather than a hardware refresh. No verified independent test of battery life, gaming frame rates or camera quality on these five Indian beta builds is available in the sources reviewed here, so performance claims would be premature.
Beta risks and rollback: read this before installing
| Decision point | What the evidence means for owners |
|---|---|
| Beta installation | OnePlus says a normal beta OTA should not deliberately erase personal data; backup is still recommended before enrollment. |
| Stability | Pre-release software can cause app crashes, black screens, lag, overheating, increased power use and missing features. |
| Battery and storage | OnePlus advises more than 30% battery charge and at least 4GB of available storage before installing. |
| Returning to OxygenOS 16 | The documented local-install rollback erases all phone data. A correct device-specific rollback package is essential. |
| 15R rollback availability | The official OnePlus 15R announcement displays its rollback download as “TBD” at the time checked. Do not assume a usable package is already posted. |
| Geography and selection | The current invitation is for supported Indian units; submitting an application does not guarantee approval or immediate OTA access. |
The distinction between updating and downgrading matters. OnePlus says the OTA upgrade is designed to retain user data, but it still advises a backup because failures can occur. The rollback process, by contrast, explicitly formats the device. That means photos, downloaded files, app data and locally stored authentication information can be lost if they have not been backed up.
OnePlus describes a device-specific rollback package installed through the local-update mechanism. Its OnePlus 15R community notice still listed the rollback file as “TBD” when reviewed for this article. Consequently, it would be unsafe to promise every participant an immediately downloadable way back. Verify a live, official package for your exact model and region before installing, rather than relying on a generic ZIP or another model’s package. This article intentionally does not provide an unverified download.
Should you put the beta on your main phone?
For a primary device used for banking, two-factor authentication, work calls, travel or emergency access, waiting for the stable rollout is the lower-risk choice. A secondary device with a tested backup is a more sensible beta candidate. Even a successful installation may need time to optimize apps in the background, and the manufacturer cautions about temporary heat, lag and elevated power consumption.
Why an India beta does not confirm a worldwide rollout
OnePlus’s published notices limit this particular enrollment window to India. The China ColorOS 17 rollout and the October 13 global software presentation concern different regions or milestones. They do not establish that a OnePlus 13R in Europe, a OnePlus 15 in North America or every other OnePlus device will receive the same beta on October 9. Likewise, a public software event is not proof of an India-wide stable OTA on that date.
Owners elsewhere should watch official regional notices for supported model codes, local build numbers, and eligibility. Software availability can vary by carrier, country, hardware variant and staged rollout. We will not infer a release date for unannounced markets.
How to report problems if you are selected
OnePlus asks beta participants to submit reproducible feedback. Its published instructions direct users to the Help & feedback section in Settings or the feedback utility accessed through *#800# in the dialer where supported. Before filing a report, note the exact build number, device model, affected app version and steps needed to reproduce the issue. Avoid sharing passwords, authentication codes or sensitive personal information in public bug reports.
When troubleshooting after installation, check for official app updates and give background optimization time to finish. If a banking or accessibility app remains incompatible, treat it as a genuine reason to stop using the beta—not as a problem that is guaranteed to resolve after a restart.
What remains unconfirmed as of October 10
- A guaranteed beta acceptance rate or the number of available places.
- The stable ColorOS 17 OTA release date for each of the five Indian phones.
- Equivalent registration windows for other countries.
- Identical feature availability across all five first-wave beta builds.
- A verified official rollback download for every model at the time of this report.
Those gaps are significant when deciding whether to enroll. The most reliable next step is to consult the relevant official OnePlus community thread for your exact phone before committing.
Frequently asked questions
Is the OnePlus ColorOS 17 Open Beta available outside India?
Not under this specific October 9–12 announcement. The manufacturer says the program is currently limited to supported Indian devices; other regions need separate confirmation.
Will applying automatically install ColorOS 17?
No. You submit an application first. Only approved participants are offered the OTA, and selection is not guaranteed.
Will upgrading to the beta delete my files?
OnePlus says the normal beta upgrade is designed not to clear data. Nevertheless, back up first because software installation can fail and beta builds can be unstable.
Can I go back to OxygenOS 16 without losing data?
Not through the documented rollback process. OnePlus warns that reverting through a local rollback package wipes the phone. Confirm an official model-specific package exists and complete a restorable backup beforehand.
Does the October 13 ColorOS 17 event mean the stable update arrives that day?
No. A global presentation date is not a confirmed stable OTA timetable for each Indian OnePlus model.
