This 108 page document will tell you everything you need to know about using the Samsung Galaxy S6 Active, including some of the more unique features like customizing the extra “Active” button you’ll find on the side of the device. It also takes you through using Samsung’s user interface on top of Lollipop, and showing you how to do stuff like hard resetting the device (there’s no removable battery) and changing the SIM card.
One thing we should note is that this manual specifically covers the AT&T variant, which — to our knowledge — will be the only variant of the phone available at launch (as AT&T has historically been the exclusive launch partner for the Active series).
We’re still digging through the manual ourselves to see what other interesting bits lie inside, and we’ll definitely be sure to share whatever we might find. Rather give it a look yourself? You can view the full thing over at AndroidForums.com.
