Samsung is reportedly working on a rugged water- and dust-proof variant of the Galaxy Note 3, according to ETNews, and is also considering making the Galaxy S5 rugged and tough out of the box, similar to Sony's Xperia Z and Xperia Z1. Samsung won't be downgrading the hardware on either device for the rugged variants, which is stark contrast to the Galaxy S4 Active, which saw its specs watered down in exchange for a tougher and resistant build.
While the Galaxy Note 3 might get a ruggedized variant, it's too early to be taking anything about the Galaxy S5 too seriously. Actually, it's best not to pay much heed to any of these rumors until something substantial turns up, though with the flexible display smartphone expected to become a reality soon, ruggedness might just be the next big feature Samsung puts its focus on.
