I'm sure most people know this already, but some may find it useful...So I've read a few complaints from people concerning this screen that pops up after completing/disconnecting a call. I've finally had my phone long enough to, personally, see the value of this screen. A few days ago I called my daughter but got no answer. After two attempts, I simply tapped "Message" to text her. Today, I dialed a number and got a busy signal. Tapping "Call" redials the number. It seems quite handy to me 
And the screen will close by it's self in about 4 seconds you do nothing.
