I'm in pretty deperate need of help as it's tough to make calls with my Note 10+. When I call someone they can hear themselves talk - when using both the native phone app and things like WhatsApp.
From my end it sounds completely normal, but they can hear their own echo. It happens on both landlines and mobile. When I use bluetooth or keep my phone on mute during the call, the problem goes away for the other person. It makes me think that it's something with the mic itself - as if there is a feedback loop. I haven't dropped it and there's no damage.
I have restarted my phone, turned on & off wifi calling/bluetooth.
Anyone have any insight or willing to help?
