I've been using my google I/O Evo for a few days now, and i've noticed that i'm having quite a bit of trouble hearing people talk during a call. My hearing is pretty average(I think?) and I'm holding the earpiece directly toward my ear. I've tried pressing the volume rocker to the max for high volume output, but callers sound extremely faint. I've never really had this issue with my past flip phones. Am I missing a volume control somewhere, or do you think i have a defective unit? Thanks guys
