This may be an S2 problem, it may be an Android problem, I'm not entirely sure. Is there a way I can switch off the visible SMS notification in the top bar of the screen but still get a message sound when one arrives? So sound only, with no onscreen notification? You know, like the old days? I can only find the option in message settings to turn off notifications, but that also turns off the message tone which I don't want to happen. Is there a setting I've missed, or an app that'll do it?
