Really like the phone - so much better than my old LG device. But - I have a problem hearing the voice of anyone calling me (or anyone I call) - the volume only goes to 10/10 instead of out of 30. This means that I have to always put the phone onto speaker which obviously leads to privacy issues. I have read elsewhere that others have the same problem but have seen no answers. Is there any way I can boost the sound so that I can actually hear someone when I am outside. I find myself asking everyone to speak up. Any views?
