To the reviewer who wanted to know about the exterior display......I find it a little annoying myself that the screen goes blank. It would have been nice if Samsung had come up with some way for it to stay on, especially since it has such a nice color screen. But in order to conserve the battery it automatically shuts off. But don't worry if you have received any messages, or have missed a call; the screen becomes active with the alert to let you know. The screen will stay on until you open the phone to view the missed call etc.Along with other reviewers I think it is rather dumb for the side key to adjust the key volume, but I've found that when on a call it will adjust the volume of the speaker.Other than a couple of annoyances that the phone is really good, solid and attractive. So far I am really happy with it.
