When connecting my samsung nx300 camera via wifi to my ipad air using samsung smart camera app I can only get a small pre-view window on the corner of the screen (80x40) The camera as been back to samsung and they have confirmed that it is working ok.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430
Doesn't solve your wifi connection problem, but you can use Apple's camera connection kit to transfer pics/videos from your camera. You can connect the camera to the iPad using a USB cable or use the camera's SD card.

That would be a question for the App developer. Whether or not they have a full screen option in the App.
