The Samsung Tocco now enables you to copy images from one location to another not unlike other Samsung devices where the images are only stored in one place. The two view modes when browsing images are the list view and the thumbnail view. Browsing images is very easy because all you need to do is sweep your fingers across the screen to move to the next image. You can zoom the image in and out but doing this is may be irritating because the transition is very slow. It is rather slow because zooming the image is done in small zoom steps which lead you to go through several steps just to obtain more detail.
Your GPS unit communicates with satellites, which send out radio signals. Since the speed of those radio signals is a known factor, the GPS receiver is able to use that speed to calculate its distance--and therefore the distance of the one holding it--from a satellite. This calculation puts you and the GPS in an imaginary sphere.
