Hello, I hope somebody can help me with a strange occurrence. When I'm using the headphones (headphones that have mic incorporated) for any music app and a call is coming. Or I'm making a call with headphones active, the microphone is not working. I can hear fine, but they can't hear me at all. I used the original headset that came in the box and an MI headset with mic that worked well with a Samsung j5 (nougat) and a Lenovo vibe shot (marshmallow). Anybody had this issue? What do I do?

The jack is clean. The phone is new and the original nokia headset doesn't work. I tryed another headset just to test the output.
