I'm very happy with the voice quality. I use mine for business and am on it constantly, and no one has complained as to how I sound. As for the signal strength, I would say it's about average, no worse then my LG Envy that I had. I notice when I am in an area with poor coverage, it sucks down the battery very quickly, trying to get a few more bars, particularly when it is looking for a 1x signal. Overall I am extreamly happy with my phone, and have no plans to retire it.
