Samsung Galaxy (stylized as SAMSUNG Galaxy since 2015, previously stylized as Samsung GALAXY) is a series of mobile computing devices designed, manufactured and marketed by Samsung Electronics. The product line includes the Galaxy S series of high-end smartphones, the Galaxy Tab series of tablets, the Galaxy Note series of tablets and phablets with the added functionality of a stylus, and smartwatches including the first version of the Galaxy Gear, with later versions dropping the Galaxy branding, until the release of the Galaxy Watch in 2018.
Samsung Galaxy devices use the Android operating system produced by Google, usually with a custom user interface called Samsung Experience (formerly known as TouchWiz). However, the Galaxy TabPro S is the first Galaxy-branded Windows 10 device that was announced in CES 2016. The Galaxy Watch is the first Galaxy-branded smartwatch since the release of later iterations of the Gear smartwatch from 2014 to 2017.
