HMD Global

HMD Global Oy, branded as HMD, is a Finnish mobile phone company, made up of the mobile phone business that Nokia sold to Microsoft in 2014, then bought back in 2016. HMD Oy (limited company) began marketing smartphones and feature phones under the Nokia brand on 1 December 2016. The company has exclusive rights to the Nokia brand for mobile phones through a licensing agreement. The company was created by inheriting Microsoft Mobile's feature phone business, which was sold to Microsoft by Nokia in 2014. HMD is in a partnership with Google, and uses the Android operating system under the Android One program on their smartphones, whereas HMD's feature phones use the Series 30+ platform, or most recently, the Firefox OS-derived KaiOS. The HMD brand is only used for corporate purposes and does not appear in advertising, whereas the name Nokia Mobile is used on social media.
