The s4 active is dust and waterproof. Has the actual hardware keys instead of the touch keys. The active has the hardware keys because you can capture pictures under water. The touch keys won't function under water.
S4 Active has an 8mp camera compared to the 13mp of the regular model s4.
Display is also a little different. The s4 active display isn't as nice as the regular s4.
I have the normal s4 model. I love it. I wouldn't have much use for the active model. But that's just my 2 pennies
Processor wise. It's the same device
