Since Android devices (smartphones, tablets, etc) aren't TRL-specific products, I won't be writing directions on how to use them. What I will do is link you to some videos which I've found helpful on how to get the most out of them.
This video covers most basic things people can do with their Android powered devices. Just like iOS, Android is pretty much the same across phone and tablets. I know KitKat isn't the newest version of Android anymore, but most of the same principles apply.
