I had very similiar issues using call and the Eco, try several options but at the end the solution was provied in YouTube "How to fix Galaxy S10 micro (echo) Easy Fix" I follow each recomendation and fixed!! @userH1inEFM60w wrote: I think the Samsung Galaxy S10 is a great computer, smart device, and camera, but horrible phone. Is no one concerned about audio quality of phone calls? The phone and speaker phone quality are horrible. Talk to someone using the speaker phone and the S10 owner sounds muffled and distant. Talk to someone while holding the phone, next to your ear, and if the other person is wearing a headset with background noise (like a call center), you get feedback in your ear everytime you talk to the person on the other end. I thought I was buying a cellphone but it is more of a media device and i would have to purchase a blutooth to make this phone usable as it is my business phone. Also the S10 has a super small hearing radius. If you wear glasses, there is no ideal spot for you to place the phone where you can hear properly. You have to place the phone in the correct position for anyone to hear what the person on the other end is saying. Unlike my S8, the audio speakers are harsh, too focused, and the microphone is a significant step down. Is this the trade off for making the speakers stereo? If you can correct this with software please do within a couple days as I will return this one in 3 days. As much as I love all the other features, the Galaxy S10 is going to be returned because it can't be used as a cell phone. I even took it to Best Buy and they opened a new S10 from a different batch and it had the exact same issues. Called Samsung and they had no solution except to take it to UBREAKIFIX and they were going to open my 3 day old phone. NO THANKS. I will trade the superior battery life, 8 GB of Ram, 128 GB of storage that is expandable, Android Pie, great camera, larger screen, and all the other improvements for a phone that I can use as a phone. This phone is amazing in almost every other way, but if you went cheap on the microphone and speakers, you missed a near perfect smartphone!!!
