Not sure what you’re talking about. But I would guess it might be port dependent. I do recordings with the phone and the jolla app all the time. Mostly in the basement studio which IS loud, but, nevertheless, the recordings are always fine. If not distorted from the excess volume in the room.
Soooo, maybe, you could be a bit more precise about exactly ‘who’ or ‘what’ is effected.
EDIT: I’m using a rephone, at the moment. And those recordings are obviously just fast and dirty. Considering the size of the microphone.
