Today, our hearts are undoubtedly heavy and mixed with emotion. As part of the proactive global strategy adjustment, OnePlus has decided to conclude new product rollouts in Europe and North America.

 

Though we will no longer launch new products in Europe, our commitment to you remains unchanged. Backed by OPPO, existing OnePlus devices will continue to receive scheduled software updates and security patches within the support periods originally committed for each device model.

 

As part of an operational adjustment to our software strategy, following the official release of ColorOS 17, users globally with existing OnePlus devices that fall within the eligible upgrade scope will have the option to voluntarily update to the latest ColorOS. This enables us to streamline software development, accelerate update delivery, improve software quality, and make better use of our shared engineering and R&D capabilities.
