I think you made an error. The Active does not have Slow mo in the video recorder, they took that out, as well as Night Detection. Im thinking of switching from the Active back to the regular S4, less missing features, better camera, more accessories, more dev support, etc...
Screen is definitely downgrade..... Now the fanboys suddenly saying that LCD has some advantages over oled but when HTC one was reviewed they say it has poor blacks and lower contrast.... Amoled is the USP of Samsung s series phones.... Contrast in s4 active is as low as xperia z.
Obvious that Samsung panicked and threw a IP-classed phone together to stop the Z. Physical button? Really? And second-grade parts. Clearly a rushed product.
Looks better than the regular S4 apart from the camera downgrade. Still, I wish people who design "rugged" phones remembered to put lanyard eyelets on them. I don't think I need to explain how useful they are when you're outdoors or doing anything "active".
