OnePlus phones will lose their signature OxygenOS interface and shift to OPPO's ColorOS starting as soon as this year, according to a new industry report. Smartprix, citing an unnamed OPPO source on July 3, 2026, says the company plans to retire both OxygenOS and Realme UI globally, moving all future OnePlus and Realme smartphones onto the ColorOS platform. The change would unify the three brands under a single software umbrella, ending years of distinct user experiences and community-driven customizations.

The report, which has not been confirmed by OPPO, OnePlus, or Realme, claims the transition will begin with upcoming devices in late 2026 and be complete by 2027. Smartprix's source suggests that existing phones will continue running their current operating systems but are unlikely to see the ColorOS overhaul. Instead, the change applies to all new models from that point forward. If accurate, it marks the final step in a slow but steady merger of OPPO's software across its family of brands.

Why OPPO Is Pulling the Plug on OxygenOS and Realme UI

The strategy appears driven by reducing duplication and accelerating updates. Maintaining three separate Android skins—OxygenOS for OnePlus, ColorOS for OPPO, and Realme UI for Realme—requires significant engineering resources. By consolidating on ColorOS, OPPO can streamline development, push security patches faster, and deliver a consistent feature set across its entire device portfolio. The move mirrors what Xiaomi did with MIUI and HyperOS, though OPPO's approach is more aggressive in eliminating beloved legacy interfaces.

Smartprix's report, labeled exclusive, provides no timeline specifics beyond "2026-2027" and does not detail whether the unified ColorOS will retain any lightweight modes to mimic OxygenOS's traditional near-stock feel. That omission leaves a crucial question unanswered for longtime OnePlus fans: will the new ColorOS preserve the speed and clean aesthetics that made OxygenOS a favorite among enthusiasts, or will it be the full-featured, often polarizing skin found on OPPO's Find and Reno series?

What This Means for OnePlus and Realme Users

For current OnePlus owners, the immediate impact is minimal. Devices like the OnePlus 13, OnePlus 12R, and older flagships will continue to run OxygenOS and receive planned updates. OnePlus has not announced any change to its update policy, and Smartprix's source explicitly says existing devices are not part of the rebranding. Realme users face a similar situation: the Realme UI you see today stays on your phone.

The bigger question hangs over future purchases. If you're eyeing the next OnePlus flagship, perhaps the OnePlus 14 expected later this year, you might be buying into a ColorOS future, not the OxygenOS experience OnePlus built its reputation on. Realme's next mid-ranger or budget phone will likely ship with ColorOS out of the box. That shift could alter the value proposition for both brands.

Here's what changes for different groups:

OnePlus loyalists: You're losing the near-stock Android feel that defined early OnePlus phones. OxygenOS 14, already sharing a codebase with ColorOS, was a departure, but it retained some distinct design elements. A full move to ColorOS would likely mean a more heavily customized interface, additional pre-installed apps, and a different approach to notifications, settings, and theming. The community-driven development that once made OnePlus a darling of XDA forums may effectively end.

Realme users: Realme UI was already a close cousin of ColorOS, so the change might be less jarring. However, Realme's software added its own launcher, icons, and minimalist tweaks that appealed to a younger audience. Under ColorOS, those distinct touches may disappear, replaced by OPPO's design language.

OPPO users: You might not notice a thing—unless faster updates materialize. OPPO's own phones already run ColorOS, so consolidation could benefit you through quicker rollouts and shared features across more devices.

Windows users with Phone Link: Many OnePlus and Realme owners use Microsoft's Phone Link (formerly Your Phone) to mirror notifications, make calls, and access photos on their PCs. ColorOS already supports Phone Link on OPPO devices, including cross-device copy-paste and app streaming. So functionality should remain intact. However, if OxygenOS had any unique integrations or optimizations for Windows, those could fade. No official word yet, but the core experience should be safe.

How We Got Here: The Gradual Erasure of OxygenOS

OnePlus launched in 2014 with CyanogenMod pre-installed, then quickly developed its own OxygenOS after a split with Cyanogen Inc. That software won praise for being clean, fast, and close to stock Android, with useful additions like Shelf, reading mode, and customizable gestures. When OPPO, its parent company since 2020, began integrating resources, the two brands' software teams merged, and OxygenOS 12 and 13 increasingly borrowed from ColorOS's codebase.

In 2021, OnePlus publicly stated that OxygenOS and ColorOS would remain "separate software products." That promise held through iterative releases, but the underlying merger was evident: OxygenOS 13 looked and felt more like ColorOS than ever, while Realme UI 4.0 did the same. Last year, OnePlus even experimented with a "ColorOS for OnePlus" option in some regions, further blurring the line.

Now, if Smartprix's source is accurate, the branding distinction itself is set to vanish. OPPO may feel that maintaining separate names no longer justifies the marketing spend and consumer confusion. The move also consolidates brand identity, potentially making it easier to market phones globally under a unified software story.

Realme's trajectory is similar. Born as an OPPO sub-brand in 2018, Realme initially used ColorOS before forking its own skin in 2020. Realme UI 1.0 was essentially a reskinned ColorOS, and each subsequent version tracked OPPO's updates closely. Retiring Realme UI would be a return to origins, albeit with a modern ColorOS like the version found on the Find X6 series.

What You Should Do Right Now

If you own a OnePlus or Realme phone, there's no need to panic. Your device's software won't vanish overnight, and you'll still receive security patches and OS updates as promised. OnePlus's update policy extends up to four years of OS upgrades and five years of security patches for flagships—that commitment isn't affected by this report.

But if you were planning to buy a new OnePlus or Realme phone in the coming months, consider these steps:

  • Wait for official confirmation. Smartprix's report is a leak, not an announcement. OPPO or OnePlus may clarify their plans, especially ahead of the next big launch. A statement could come within weeks.
  • Try ColorOS before committing. If you're near a store that sells OPPO phones, spend time with a ColorOS device. Navigate the settings, check the notification shade, and assess whether the customization matches your taste. ColorOS has improved dramatically—it's fast, feature-rich, and now less bloated than older versions.
  • Back up your data if you plan to switch ecosystems. Whether you move to a different Android brand or even consider iOS, having a recent backup ensures you don't lose photos, contacts, or messages.
  • For business and IT admins: If your organization deploys OnePlus devices because of OxygenOS's simplicity and security posture, start evaluating how ColorOS's feature set and management options compare. The change could impact user training and device management policies.
  • Watch out for resale value. If demand for "last OxygenOS OnePlus" spikes, prices might temporarily rise. Conversely, a glut of used devices could lower values. Monitor marketplaces for trends.

The bottom line: don't make a rash decision based on an unconfirmed report. The tech industry is full of strategy shifts that get reversed. But if you prioritize a stock-like Android experience above all else, it's wise to keep an eye on alternatives like Google's Pixel line, Nothing Phone, or Motorola's near-stock offerings.

Outlook: What to Watch Next

All eyes now turn to OPPO/OnePlus for an official response. The timing of Smartprix's leak—early July 2026—could be calculated to gauge public reaction before a formal reveal. If the backlash is fierce, OPPO might attempt a compromise, perhaps offering a "stock mode" toggle within ColorOS or keeping the OxygenOS name for select markets. Alternatively, the company could accelerate its plans, seeing the leak as a way to soften the blow.

For Windows users, the consolidation may eventually simplify the Android-to-Windows connection experience if OPPO invests in a uniform Phone Link integration across all its brands. But that's speculative. The immediate watchpoint is the next OnePlus flagship announcement, expected in the fall, where any software brand change would logically be debuted. Until then, treat the report as a strong signal, not a final verdict.
