Headphone one side working s7 edge samsung

[Kooki]

I started having a problem with headphone jack S7 edge last week. Earphones would only work in the left side. I thought my earphones were broken, so I checked on another device both ear pieces work fine. I put my aux cable into the jack in the car, only the left stereos in the car work even tho when I turn on the radio both right and left stereos work.
I checked the phone's sound settings, bass treble instrumental and vocal are all centered. Equalizer is at normal. (Picture

Help? How can I get both sides of earphone to work?

Thanks.
