Samsung Galaxy S4
The Samsung Galaxy S4 is a series of high-end Android smartphones produced by Samsung Electronics as the fourth smartphone family of the Samsung Galaxy S series 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, more sensors, 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, it was released the previous year. A hardware variant of the S4 became the first smartphone to support the emerging LTE Advanced mobile network standard (model number GT-I9506 and SHV-E330). The T-Mobile version of the Galaxy S4, named the model (SGH-M919), was released the same month. The phone's successor, the Galaxy S5, was released the next year.
The Galaxy S4 is among the earliest phones to feature a 1080p Full HD display, 1080p front camera video recording, and among few to feature temperature and humidity sensors and a touch screen able to detect a floating finger.
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.
In total, more than 80 million Galaxy S4 units have been sold, making it the most selling Android-powered mobile phone of all time.
The Galaxy S4's successor, the Galaxy S5, was announced by Samsung in February 2014 ahead of a release in April of that year.
The Galaxy S4 uses a refined version of the hardware design introduced by the Samsung Galaxy S III, with a rounded, polycarbonate chassis and a removable rear cover. It is slightly lighter and narrower than the Samsung Galaxy S III, with a length of 136.6 mm (5.38 in), a width of 69.8 mm (2.75 in), and a thickness of 7.9 mm (0.31 in). At the bottom of the device is a microphone and a micro USB port for data connections and charging; it also supports USB-OTG and MHL 2.0. Near the top of the device are a front-facing camera, an infrared transmitter for usage as universal remote control, proximity, and ambient light sensors, and a notification LED. In particular, the infrared sensor is used for the device's "Air View" features.[citation needed] A headphone jack, secondary microphone and infrared blaster are located at the top. The S4 is widely available in black and white color finishes; in selected regions, Samsung also introduced versions in red, purple, pink, brown with gold trim, and light pink with gold trim. In late January 2014, Samsung's Russian website briefly listed a black model with a plastic leather backing, similar to the Galaxy Note 3. On 6 February 2014, the Korean LTE-A model got three new colors, those colors being Rose Gold White, Rose Gold Black, and Deep Black.
The S4's 5-inch (130 mm) Super AMOLED display with 1080×1920 pixels (1080p Full HD) is larger than the 4.8-inch (120 mm) 720×1280 display of its predecessor, and also features a brand new "Diamond" PenTile RGBG matrix subpixel arrangement which has a better subpixel fill-rate for any given resolution than the traditional linear RGBG PenTile layout that had been used prior (there's less empty black space between each subpixel). The whole pixel density also increased from 306 to 441 ppi, surfaced with Corning Gorilla Glass 3. An added glove mode option increases touch sensitivity to allow detecting touch input through gloves. The Galaxy S4 is Samsung's first and one of the earliest mobile phones of all time to feature a 1080p display.
Unlike previous models, the S4 does not contain FM radio support, citing the increased use of online media outlets for content consumption on mobile devices.
