OnePlus plans to bring its OnePlus Care app to North America to help phone owners who need service support. The after-service management app will be coming to Canada and the US in "late November." The OnePlus Care app can be used to track a device's repair status. Of course, this app will only be useful if you have a secondary device to install it on.
OnePlus has a paid OnePlus Care service in India. It isn't clear if the company plans to bring that to North America as well.
