Help What Are the Functions of the Earphone Microphone Button (apart from accepting calls)?

[cf1572]

Hi,

I have a phone with Android 6.0. And when I listen to music I use the button on the earphone microphone to Play/Pause music by clicking once. And skip the track forward by clicking twice. Sometimes when trying to skip the track the sound goes up, but I don't know why?

Also, what other functions can I do with the earphone microphone speaker button (apart from accepting and rejecting calls)?

Thanks
