Phone calls: other person suddenly can't hear me anymore

Official support can be contacted here - the forum is more of a community effort and there is no guarantee that official support will read what’s discussed here (though sometimes they do), which is why it’s best to contact them directly if you need an official answer.

Also: @Rosamartillo and @isl73: I’ve moved your posts here as I get the impression you’re describing that this happens during a phone conversation (rather than that it is the case from the very start of each conversation). As more people are discussing that here, there’s a better chance of a solution being reported here. If I got this wrong, let me know and I’ll move your posts back.
