I have a Moto Z 2 phone and T Mobile service. When I call from my easy chair or even outside my house, I can hear clearly, but can not be heard clearly. This seems to be a problem with my location. My sweetheart does not have any trouble hearing when I call from work. I have not had any issues with Boost and LG phones, or AT&T with Samsung. My Google searches were not very helpful. I do not use Google voice and think I have ensured that it is shut off. I really like my Moto phone other than this issue. I am using a plastic protective cover that does not cover the front. Any solutions to the being heard clearly issue.
