I have a Samsung Galaxy s9 and shortly after getting it I began having problems with people hearing me over phone calls. I can hear them fine, but I also get a bad echo of my own voice when I talk (worse when I use speakerphone). I can use headphones and they can hear me then, and if I am using a video app like Google Duo they can hear me as well. I have tried my SIM card in a different phone and it worked fine, and I can use record videos and audio on my phone and hear just fine. Tried restarting in safe mode and that didn’t fix it either. Anyone know what the issue might be or other possible ways to fix it?
