Since I have the Fairphone 4 I experience poor audio quality during conversations with speakers.
Its not the sim. I replaced it to rule out.
Its not the provider. I did not have any issues with other phones nor anyone in my house.
I do not have a cover of card over the phone.
No problem with sound quality while listening to music via speaker or earplugs.
People on the other line hear only fragments of words. Its only when I use the speaker option.
Any tips besides buy another speaker in the webshop? Or other phone?
