There are a umber of posts around the two issues (volume, echo) and if a user has different experience that the one described below please see the other topics
My daughter and I experimented yesterday and have the following repeated results.
It appears that only the top microphone (mic2 in the Service test) is being used
The first issue, volume, is to do with the handling. My daughter often uses hands free when walking and in that situation the top mic is well below the head and pointing away from body. In my case I usually have it propped against my computer screen almost vertically in front of my face and a speak across the top of the top mic.
In my case the volume is fine, in my daughters it can vary and be very low so she uses earphones. We swapped options to confirm that the low volume was a result of the angle of the top mic to the speaker this is made more pronounced when using the case as the top mic is indented more and adds to the deprecation when walking etc. with the phone held in front and angled away from the body.
It is clearly the top mic as covering the bottom mic has no effect and covering the top just about drops the voice to zero+
The second issue is the echo. I can now replicate the issue, again I did this test with the phone vertical, in front of me some 45cm away. The echo is very pronounced when I lower my voice, if I talk loudly there is none.
I will be contacting official Fairphone with this data
So if you can replicate the above please confirm with some simple reply here, Thanks
