Samsung's latest iteration of its flagship smartphone, the Galaxy S4, features a first-party game controller accessory similar in design to Microsoft's Xbox 360 controller.
The design is composed of plump curves, dual analogue sticks, a D-pad, candy-colored face buttons, a string of five small menu buttons, and left and right shoulder buttons on its backside.
It physically attaches onto the smartphone via an expandable clamp, connects to the smartphone wirelessly and is powered by dual-AA batteries.
Engadget reports the accessory displayed is a concept; however, it is expected to launch this Summer.
The Galaxy S4 will ship out with an Android 4.2.2 Jelly Bean operating system, 2GB of RAM and will feature an Exynos 5 octa-core 1.6GHz processor or a Snapdragon 1.9GHz processor, depending on the region.
The S4 sports a 5-inch 1920x1080-pixel HD Super AMOLED display with a pixel density of 441 ppi, built-in Near Field Communication (NFC), a 13-megapixel rear-facing camera, with model variations in internal storage capacity: 16, 32 or 64GB.
Pricing hasn't been announced for the new smartphone but it will go on sale globally around April to June.
