Ok, maybe there is some kind of setting in the settings section that can fix this (and if there is, I obviously missed it, so please tell me!)...but I find the hero to be VERY quiet when I'm on a call. I turn the volume all the way up and I feel like I'm still straining to hear sometimes. Maybe I'm just going deaf? I dunno, but other than that, I love the phone, I do have to go buy call caddy to lock the screen, as I end up doing everything from creating a new text to starting a 3 way call when I'm on the phone! lol! Is there any kind of app out there that will amplify the sound when I'm on a call?
