Differences between objects positions in "zoomStretch", in "zoomEven" and on the simulator

I write a application for iPhone4/4s, for Galaxy S2/S3 and HTC devices. What is advanced scaling for it (I guess I have to choose between “zoomStrech” and “zoomEven”) and what are differences between these two scalings?

I got that the circle in “zoomStretch” will look like an ellipse, but the main issue that I have that the text and pictures ,that looks ok on simulator, moves up/down/left/right on device. I have the same issue with “zoomEven”. Why does it happen? [import]uid: 172733 topic_id: 30402 reply_id: 330402[/import]

zoomStretch will stretch to fill the whole screen, zoomEven will stretch to as big as it can without messing up ratio and letterbox will show black bars if the screen dimensions are off from what you’ve set in build.settings, just like a widescreen movie.
