Sony Ericsson S710a new high-end swivel camera phone for Cingular

The S710a actually has 2 keypad areas, one for the navigation controls which are on the phone's face, and a second for the numeric keypad and power key which is under the spinning face. The navigation keys on the face allow you to do pretty much everything - including make phone calls - without spinning the phone open. When the phone is open, the numeric keypad is close to the navigation keys, so you don't have to move your hand too much to use all the keys.

All of the keys are quite flush with the surface of the phone. The navigation keys are completely flush, while the numeric keys are slightly below the keypad surface, leaving a slight indent where each key is. The D-Pad select key is the only key other than the volume up down keys on the side of the phone that can be felt for without looking.buy meizu mx3 However the D-Pad select has problems of its own. On first glance it appears to be a joystick, as is common on most Sony Ericsson phones. However the direction keys are the ring around the joystick, which serves solely as a select key.

Since not all the keys are hidden when the phone is closed, Sony Ericsson devised a very useful keylock. Instead of a key combination, the keylock is a dedicated slide switch on the side of the phone.
