(Telecompaper) HTC has unveiled its new flagship smartphone, the U12+. With the slogan 'living on the edge', the device builds on the previous HTC squeeze features to allow users to control the 6-inch device with one hand touching the edges. The Edge Sense 2 system recognises which hand is holding the phone, so gestures such as squeezing the device, doubling clicking the side or holding down can launch common functions such as the camera, zooming in a map or navigating the screen.
