Anyone know if there is an app to hide the notification bar at the top and make it show up only when there is a notification?
There might be but I haven't seen one. The only thing that I can think of is you may be able to do this if you know how to use the Android SDK. If you don't, I wouldn't advise trying until you have experience in programming, but I would learn if I was you. I just started to learn Java a little while back and now that I have an Android phone, I've been working on programming and making apps for my phone.
