Hello, hello… I can hardly hear you, could you speak up a bit?
Meanwhile I am talking really loud into my phone, and after several calls this way, it was Dr.Google to the rescue…
My Samsung S5 mini works fine, but people on the other end of the call hear me as if I was talking 10 meters away from the phone.
“Clean out the tiny microphone hole with a pin”
Really, that was it; just dirt and dust blocking my voice. Glad people can hear me again, without having to scream.
