I asked this before, but maybe it got posted in the wrong place, as I got no reply. When I call using my FP4 with the Google Phone app, if I use speakerphone, the sound is muffled and often inaudible at the other end. I think this is a software problem with Android 15 (which is completely up to date on my phone). On Whatsapp the sound at the other end is fine, so it seems to be a software problem rather than hardware. I even attached an external bluetooth mic, but the fuzziness persisted. Has anyone else had this, and is there a solution, apart from only using whatsapp?
