Headphones button on zuk z2 pro is not working

[KarkaLT]

Hello,
I'm using single button headphones from Samsung. When I'm listening to music on Play music when I press the button it should pause/play music, but when I press it turns up sound volume. Is there are any ways to make it work properly?

Update: I tried same headphones on other device and button does what it should do. It's some kind of phone related issue.

It's happen sometimes, You need to clean the hole when you put in your headphone.
