The S4 Active was first released in the United States by AT&T on 21 June 2013 in "Dive Blue" and "Urban Gray" colors, its model number is SGH-i537.
[3] The S4 Active inherits most of its hardware components from the S4, including an identical Snapdragon 600 quad-core processor, 2 GB of RAM, and a 5-inch 1080p display.
The S4 Active is designed towards the IP67 specifications, meaning that it can withstand up to 30 minutes underwater at a maximum depth of 1 meter (3.3 feet), and is also resistant to dust.
[4] An update to Android 4.4.2 "KitKat" was released for the AT&T model in April 2014, although the deployment was temporarily halted until June 2014 due to technical issues.
However, regressions from the S4 were also noted, such as its lower display quality in comparison to the Super AMOLED.
