@CountTuscany: When the phone is in portrait mode, the area you've highlighted is where the Notification Bar would sit. When you turn it to portrait, it leaves this area blank. I understand that it creates a minor symmetry problem, however this is due to the Navigation Bar being hidden in Full Screen Gesture mode.
Sorry for the confusion. With the Navigation bar in place (not hidden) it makes the keyboard position look more central and draws less attention to the gap left by the Notification Bar. I checked Google Maps in landscape and this also left a gap where the Notification Bar would be in portrait. I do understand your concerns, however this is likely to be a design choice influenced by the positioning of the camera.
