Just got my s6 now to root it!

Okay so about 3 hours ago I got my galaxy s6 and no I wish to root it although I'm out of the loop on what's going can someone clarify for me?. I keep seeing that root isn't supported on 5.1.1 luckily for me I'm still on 5.0.2, I tried ping pong root but that didn't work so now I'm thinking of using cf autoroot. I keep seeing people saying that after root they can't hear when making a call or that data is not working I'm just wondering what's going on? I just want to get updated :)
