Samsung Galaxy S4

The Samsung Galaxy S4 is an Android smartphone produced by Samsung Electronics.


The Galaxy S4 was made available for retail in April 2013. Billed as an upgrade of the best-selling Galaxy S III, the S4 was arguably the most hotly anticipated smartphone release of the year. Whilst maintaining a similar design to the S III, the S4 has upgraded hardware and more advanced 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, which includes scrolling.

The S4 was made available in late April 2013 on 327 carriers in 155 countries. Upon its release, it became the fastest selling smartphone in Samsung's history; the company sold 20 million S4 units worldwide in the two months following the device's launch.  Samsung has since sold more than 40 million units.


Critical reception for the latest entrant to the Galaxy S family has been largely positive. Most critics would recommend the Samsung Galaxy S4 as a solid, first-rate smartphone, although some have criticised Samsung's use of pre-loaded apps and features that you would likely never use, and others have expressed hopes that the S4 marks the end of Samsung's plan to add too many new features with its flagship smartphones. Nevertheless, Time's McCraken says the S4 is a smartphone with everything, it has the biggest screen and the most built-in features.


Consumer Reports named the S4 as the top smartphone as of May 2013 due to its screen quality, multitasking support, and built-in IR blaster.
