This may be common knowledge, but whenever I get a notification alert (for a new email, text, etc.), I don't get another audible alert until I have checked the notification bar. What's up with that? Maybe the first alert was an email that I don't care about, so I ignore the alert. But then if a text came in after that that I really wanted to know about, I wouldn't know about it until I actually checked the notification bar. Any solutions?
