On my moto e4, unless I'm using headphones, the call volume is WAY too loud when turned all the way down. I'm afraid to answer my phone at work because the entire room can immediately hear everything that the other person is saying - and I need to be able to answer and find out who it is long enough to tell them I need to step out. But sometimes even the greeting is more information than I want my coworkers to know. Does anyone know how to fix this?
