Touch Screen Tips

With the touch of your finger, you can access available applications, make menu selections, and access data saved to your phone. The following terms are used for describing the different available actions using the touch screen:

  • Tap - A single finger tap selects items, links, shortcuts and letters on the on-screen keyboard.
  • Touch and hold - Touch and hold an item on the screen by touching it and not lifting your finger until an action occurs. For example, to open a contact's available options, touch and hold the contact in the Contacts list unil the context menu opens.
  • Drag - Touch and hold an item for a moment and then, without lifting a finger, move your finger on the screen until you reach the target position. You can drag items on the Home screen to reposition them.
  • Swipe or slide - To swipe or slide, qickly move your finger across the surface of the screen, without pausing when you first touch it (so you don't drag an items instead). For example, you can slide the screen up or down to scroll through a list, or browse through the different Home screens by swiping from left to right (and vice versa).
  • Double-tap - Double-tap to zoom on a Web page or a map. For example, quickly double-tap a section of a Web page to adjust that section to fit the width of the screen. You can also double-tap to zoom in and out when using Maps.
  • Pinch-to-Zoom - Use your index finger and thumb in a pinch or spread motion to zoom in or out when using the browser, Maps, Camera or browsing pictures.
  • Rotate the screen - From many applications and menus, the orientation of the screen adjusts to the device's physical orientation.
Proximity Sensor

When receiving and making calls, this sensor automatically turns the backlight off and locks the touch keypad by sensing when the phone is near your ear.When you attempt to turn on your device using the KnockON, an obstructed or blocked proximity sensor will prevent the touch keypad from turning on. This prevents the touch keypad from activating unintentionally during calls or when in your pocket or handbag.
