as I can do totally responsive application to different screen sizes, in the corona emulator shows the scenes well, but in a real mobile device some things move
You really have to be a bit more precise. Do the objects move when you change the simulated device as well or do they only move on your devices? It’s most likely that you’ve placed them using absolute coordinates, e.g. local rect = display.newRect( 200, 200, 200, 200 ), where the rect will appear in a different position on screens with different resolutions.
