I was in a call, using earphones, when I got a text (spam no less), which produced a painfully loud beep, not the notification sound. I was sure there was a way to disable or attenuate notifications when in a call, or using headphones, either way. I can't find a setting for it though, and don't want to turn down my normal notification volume. I'm using handcent, stock rooted bionic, have the handcent option for sounds in call off, what am I missing? thank you
