The volume on my Revolution is very quiet even at maxed volume. It is next to impossible to talk on speakerphone when driving and my car is not very loud. And even with a wired stereo headset I can't hear pandora or the sirius/xm app in the gym over the sound of treadmills. I never had this problem on any of the my previous android phones (og Droid, Droid x and Thunderbolt). Anyone else have this problem? Any fixes for it?
