Linux kernel newbies em português

Upgraded from an S3 to an S5 Active. The guy at the ATT store (can you believe this) was not able to tell me the difference between a regular S5 and an S5 Active. I got the Active, at least already knowing it was more water and shock resistant than the regular S5 (from reading reviews beforehand).

What I did not know is that there is an extra button called the Active button. I've no interest in all the Active bloatware Samsung offers and was glad to find out the button is totally programmable (it now launches the LED light with a short press and the camera with a long press).
