I just got my wife a Brand new Samsung Galaxy S9 Plus for christmas. Seems to work fine except the speaker phone. When I talk to her and she has it on speaker phone it echos back and sounds like your under water and breaks up. I have now seen a lot of problems with the speaker phone. We are on At&t her s8 plus did not do this and I have a s 8 plus still and it does not do that. So its not the network. Has anyone found a fix for this?
