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 Samsung Galaxy S series of high-end smartphones, the Samsung Galaxy Tab series of tablets, the Samsung Galaxy Note series of tablets and phablets with the added functionality of a stylus, and smartwatches including the first version of the Samsung Galaxy Gear, with later versions dropping the Galaxy branding, until the release of the Samsung Galaxy Watch in 2018.
Samsung Galaxy devices use the Android operating system produced by Google, usually with a custom user interface called One UI (with previous versions being known as Samsung Experience and 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. In April 2019, the company announced that it would postpone the release of its folding smartphone, the Samsung Galaxy Fold, days after several early reviewers said the screens on their devices had broken. A new launch date was not announced.
