On my third Razr Maxx. Overall pleased. Got a year out of first before speaker gave out. Second was my fault . . . broke the glass. This third phone has a problem that baffles me. My earphones work great with Spotify, but I can't get hardly any volume out of the earphones when using Phone or BeyonePod. So I suspect it's a software issue, rather than lint or an issue with the jack itself. Any thoughts?
