South Korea's SK-Telecom already has a variant of the GS4 to surf its LTE-Advanced waves, and now it appears Samsung will release a version of the Galaxy S4 Active that plays nice with the carrier's next-gen network. A flyer posted on a Korean-language website revealed the handset and detailed its specs, listing a 2.3GHz quad-core Snapdragon 800 processor, a healthy horsepower boost from the original's 1.9GHz quad-core Snapdragon 600. What's more, the smartphone now sports a 13MP camera -- which matches that of the vanilla Galaxy S4 -- and its storage has doubled to 32GB. Besides shaving off a few grams in weight and nabbing a white color option, the device retains the rest of its predecessor's features, all the way down to its 5-inch 1080p display and 2,6000mAh battery. It's not clear if a revamped GS4 Active will make its way to other territories sans LTE-A, but adventurous (and clumsy) souls can keep their hopes up for a more powerful incarnation of the ruggedized phone.
