can't change songs when handsfree are plugged in

Hi there!! I recently got this LG G Flex from Sprint, I like the phone but there's one thing that really bothers me which is the fact that I can't skip tracks when I'm listening music, every phone I ever had when you press the handsfree button will pause or play the song, but this one opens the phone app and that's annoying since I don't like to pull out my phone to skip a track, I tried downloading headset control app but none of them work!! PLEASE HELP!!!
