Samsung Galaxy (stylized as Samsung GALAXY or 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 the first version of the Galaxy Gear smartwatch, with later versions dropping the Galaxy branding.

Samsung Galaxy devices have traditionally used the Android operating system produced by the Open Handset Alliance led by Google, usually with a custom user interface called TouchWiz. This tradition was broken at CES 2016 with the announcement of the first Galaxy-branded Windows 10 device, the Samsung Galaxy TabPro S.

The Samsung Galaxy S4 is an Android smartphone produced by Samsung Electronics and was first shown publicly on March 14, 2013 at Samsung Mobile Unpacked in New York City. It is the successor to the Galaxy S III which maintains a similar design, but with upgraded hardware and an increased focus on software features that take advantage of its hardware capabilities—such as the ability to detect when a finger is hovered over the screen, and expanded eye tracking functionality. A hardware variant of the S4 became the first smartphone to support the emerging LTE Advanced mobile network standard.

The S4 was made available in late April 2013 on 327 carriers in 155 countries. It became Samsung's fastest selling smartphone, with 20 million sold worldwide in the first two months, and 40 million in the first six months.
