Samsung Galaxy S4 - online puzzles

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 and eventually Samsung ’s best selling smartphone with 20 million sold worldwide in the first two months, and 40 million in the first six months.

While some users called all new Galaxy S4 features " innovation ", others called them feature creep or just gimmicks. Those features are, for example, Smart Pause, Smart Rotation, Smart Scroll, Air View, Air gesture, Story Album and Temperature and humidity sensors.
