Rumor | The OnePlus 10 Pro's global units will definitely stay on OxygenOS 12 at launch

OnePlus has been developing its custom OxygenOS (OOS) Android skin for its smartphones for years. However, this once-lauded ROM is now set to be discarded in favor of new software resulting from the brand's "integration" with its erstwhile sister-brand OPPO. Official confirmation of this situation has led to speculation that the 9 and 9 Pro might have been the last flagships to launch with the latest version of OOS.

Even OnePlus had projected that the impending global version of their successor would be the first to debut with its new build. Its CEO, Pete Lau, had already outlined plans for this new "unified and upgraded global OS", indicating that it is to combine the best aspects of OPPO's ColorOS (currently used by 10 Pro units already on sale in China) and OOS.

However, according to the leaker Yogesh Brar, the next-gen firmware is not ready to supplant its predecessor quite yet. Then again, this may enable the international 10 Pro to announce itself as the first smartphone to launch with OxygenOS 12 out of the box instead.
