Rugged Galaxy S4 apparently isn't the only Galaxy in the works

Samsung Galaxy S4
When the tough get going, Samsung gets tough

The Samsung Galaxy S4 hasn't arrived everywhere globally yet, but rumors of Samsung readying a newer, more durable version of its flagship are already making the rounds.

Those initial reports gained a little more traction today as sources revealed to the Wall Street Journal Samsung was indeed working on a tougher S4.

Hangin' tough

The only other comparable device due to arrive this year would be Sony's Xperia Z, which will also be dust- and waterproof, but doesn't quite carry the same recognition as the Galaxy line of smartphones.

Samsung is also looking to take a bit of the business clientele away from BlackBerry, as its Q10 is aimed squarely at the same corporate market.

In spite of the Galaxy S4 shortages, Samsung has still been tearing up sales charts around the world, and the added variety and options reportedly in the works should only help distance the Korean manufacturer from rival Apple.
