Datasheet

Figure 1-1 depicts a common layout of a Smartphone device. Although color doesn’t appear in these
screenshots, a color screen at the top and the number keys at the bottom are the most common elements.
What separates a Smartphone from a PDA are the software keys. Notice the two soft keys (left and right)
directly below the screen. These correspond to the menu bar and commands at the bottom of the screen.
Depending on how applications define the functions of the menu bar, these soft keys may perform spe-
cific tasks. Also note the five-way (up, down, left, right, and “Select”) navigation pad and the four fixed
function keys: Call, Home, Hang Up, and Back. Pressing the Call key will bring you to the phone call
screen, where you can enter a phone number. After you enter a phone number, pressing the Call key
again will initiate the call. The Hang Up key, of course, is used when you want to end a call. The Home
key always takes you to the home screen shown in this figure, and the Back key enables you to go back
to the previous screen. At the home screen, pressing any number key will automatically bring you to the
phone call screen.
