I have a weird problem with my Nokia headset wh-208.
For some reason they stopped working in Lumia 640xl. Although they works perfectly in other devices like Pc.
Thanks for the answers!!!
I tried other headphones and they work perfectly in Lumia 640xl except for wh-208. It's very strange.
Also wh-208 works normally in other devices. When I put them I can hear the speaker but the device can't recognized them...
