Hello, I heaving problem with my s8 plus. While I am speaking at the phone the headphone and the microphone goes dead. The phone is still working but I can not hear anything and the same the other, they can't hear me. If I goes to see a video the voice is dead too!! I make a restart and then the phone works aga in normally. Does anyone knows something about my Problem nah how can I fix it? Thank you

Does this occur only on phone calls? What about when listening to music on the headphones?

I don't use headphones. It happen only when I am on a call and it doesn't happens always. I hear inter net radio and it is ok.

So you mean you are making calls just using the phone and the earpiece and microphone go dead? I also read your first post and assumed you were using headphones with a mic in the flex.

These are standard voice calls, not voice over IP? Just asking because if you also have problems with sound when watching videos that suggests it's the audio system that goes on the blink, but if these were internet calls then there would be an additional common factor. When this problem starts does the speaker work for other sounds?

To be honest this is not normal, and the phone is new, so I'd be tempted to just get it replaced. If it only affected calls there'd be a chance that it was a network problem, but if I'm reading your post correctly that's not the case.

I don't make calls with internet. I use mobile company to make calls. The problem  starts when I am spinking on the phone the microphone and the headphone goes dead. At the test I make at the phone I found that nothing that use voice  was working ,video music....  I make restart and everything is working again.
