Hello, coming from IOS I have figured most things out but there is one thing I am a little confused on. On IOS when I was on a phone call and talking to someone it was easy to put them on speaker phone and tap the home button and then go into the internet while still being able to talk to them, then when I wanted to RETURN to the call there was always a green bar at the top of the screen that you tapped and instantly were back at the phone. I am a little confused on how one does this on the galaxy s3, could you please give me some advice on how you do this. I see a green bar on top of the s3 but when I tap it, it does not send me directly to the phone, I need some guidance here, thanks.
