Trails on the sand are usually done with Projectors, which works well on PC (but it will cause the area which it hits to be redrawn, increasing the draw-calls and lowers performance somewhat), but on Mobile phones it’s to slow and can’t be used.

You may also want to try out working with decals, though that may not be perfectly suitable for uneven terrain like a sand dune.
