Diferent objects positions over a large .jpg image (some devices)

Hi everyone!, me and my enterprise are working on an exciting new app.This app has an scene that has a map inisde it, a really huge image; there are some paths over this image conecting diferent cities in the map.

Our problem comes now: on some devices(for example, galaxy tab 2 or nexus one) this paths are not in their correct positions, but in all other devices it just run as intended

Anyone have any idea about what’s happening?

Thanks in advice. :slight_smile:
