What alot of people do to try and imagine what a 4.7 inch screen phone would feel like is draw and cut out on a piece of cardboard or card-stock the height and width of the device and try to play around with it. Like hold it up to your ear to see what it would look like to talk on it, see how well it would fit in your pocket, etc. If you plan on doing this the specifications for such phone are:
5.18 x 2.78 x 0.39 in inches or
131.5 x 70.7 x 9.9 mm in millimeters
Also, someone said about the screen resolution. The other day phonearena posted up some pictures of up close shots of the screens of the Galaxy Note, Galaxy SII, HTC Titan, and the iphone. Here is that article for you to see:
