Samsung microphone problem?

Homer_67234xlHello, 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…

The issue:
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.

The solution:

“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.
