I like the idea of the fairphone. I also own a fairphone 4. but honestly the service sucks. When talking on the phone people don't understand me because the sound is muffled and there is a lot of echo.
This is a know issue since FP 3. Also the brand new FP5 has it. So basically a lot of users have a phone that does not work as a telephone and the only thing the customer support offers is "please reset to factory defaults".
