Occasionally I'll start an app only to be presented with the App's title bar and a black screen. Usually the app's interface shows after 3-10 seconds. Very rarely the screen will stay black. I don't have any real idea about why or how to reproduce it.
I'm wondering if this is simply the phone working to try to start the app or maybe I've got too many other applications open?
Is there some way to reduce/prevent apps from showing a black screen at first and/or not opening at all?
