Are your sprites in an atlas? What shader are you using? The normal map and sprite texture may be the same size, but it looks to be choosing completely the wrong UVs to unpack the normals.

hmm. So I'm guessing you're not using Unity's own sprite packer then (since, in my experience, exporting the atlas from that is a PITA!) but it shouldn't matter.

Wondering if the Android platform is significant... something to do with float precision, perhaps? Does a Windows standalone build work ins$$anonymous$$d?
