From what we can see, the new smartphone runs Android 4.4.2, and has the same quad-core 2.46GHz Snapdragon 801 processor as the regular S5, plus 2GB of RAM. The screen of the S5 Active is a 5.1-inch 1080p Super AMOLED one, but it’s said that it’s “less washed out” and looks better.
The frame around the S5 Active seems to be made out of metal (with rubber encasing it - for more ruggedness, and probably a higher resistance to water). Unlike the regular S5, which features a 16MP rear camera with digital image stabilization, the S5 Active appears to have a rear camera with optical image stabilization (OIS).
Another novelty of the Galaxy S5 Active is that it comes with an Activity Zone app that provides info from the device’s barometer and compass. The Activity Zone app can be directly opened with an Active Key that’s found on the left side of the handset (this also functions as a camera button).
The S5 Active that's presented in the videos is the SM-G870A variant, which should be released by AT&T in the US at some point (probably in the near future). In case the videos are taken down (which might actually happen pretty soon), we got you covered with some images - included after the video slideshow:
