Samsung's Galaxy S 4 Active -- a dust and waterproof version of the company's flagship -- is currently just a rumor, but documentation has started popping up online to lend some corroboration. A handset going by the handle GT-I9295, which SamMobile has linked to the S 4 Active, has shown up in a Bluetooth SIG filing. Furthermore, a user agent profile for the same model lists the display resolution as 1080p, matching that of the standard GS4. With all these small clues pointing in the same direction, the existence of an S 4 for outdoorsy types is starting to look more like a dead cert.
