The multi-touch sensitive LG GD900 Crystal is also unique with respect to having its crystal keypad act as a touch-sensitive controller. The keypad registers gestures and hence users can just swipe their fingers on the keypad (or conventionally on the touchpad) to navigate through and access various applications loaded on the main menu. Multi-touch capability can be used to zoom into the images. Also, web pages can be enlarged by similar gestures (such as rotating the fingers) on the keypad.
The LG GD900 Crystal is packed with several touch-sensitive features as well. You can open the contacts by just drawing a circle on either the touchpad or the crystal keypad. However, this might also lead to some mishaps such as scrolling through various icons at the same time besides opening your contacts menu. Since the entire screen is touch-sensitive, it is your responsibility to be really careful while accessing a particular application.
The homescreen can be customized via an exceptional function called ‘water drops’ that turns the shortcut icons into water drops. However, it does not speed up the application start-up time and it might take a while to open the calendar. Another interesting aspect is that the phone offers 12 gestures to access 9 applications on the main menu.
Plus, the LG GD900 Crystal is the first of the S-class handsets with a hand-writing recognition feature. Users can have the text typed by just swiping their fingers either on the touchpad or keypad. Moreover, deletions can be done by just a simple swiping gesture on both the pads. However, there is an alternative on-screen QWERTY keyboard that leads to better typing owing to the more discernible letters but still you need to type slowly.
The phone has a camera shutter button and a volume rocker on the body that prove to be easy and quick shortcuts.
A few more apps accessible through gestures would have been a more welcome change, but looking at the immensely smooth user interface, the LG GD900 Crystal deserves 4 out of 5.
