Of course, this requires you to carry around the stand with you, but for those whose face turn green with envy everytime video chat is discussed, this is an intelligent solution. The Vainworks Stand costs $17.95 each or you can buy two of them for $25 with $5 shipping.
Not every smartphone with a camera on its back is a good candidate for using this product. The manufacture suggests that the camera be 1/2 inch or less from the side of the body of the phone for it to work in portrait mode. The camera needs to be 1/2 inch away from the top of the device to work in landscape mode. If the camera is 1/2 to 3/4 inch away from the phone's body, the Stand will be usable but some part of the camera might show up in the picture. If the camera is more than 3/4 inches from the phone's body, the Stand will not be useful.
