> Android One is a family of third-party Android smartphones promoted by Google. In comparison to many third-party Android devices, which ship with a manufacturer's customized user interface and bundled apps, these devices run near-stock versions of Android with limited modifications, and a focus on Google services (although they may still feature software enhancements to support the features of included hardware, such as cameras)
