@dothem Hey so I just checked the shaders out on android and it all works for me ALTHOUGH - do check what your pixel light count is when running the game I reckon that will be whats making pixel lighting not work for you.
Go to Quality settings inside of Project Settings.
For each of the quality settings (Fastest/Fast/Simple etc) check the pixel light count.
If its zero then pixel lighting won't work, and you should use Vertex lighting instead. Less than 4 means less lights will effect objects than when using vertex lighting so it will look noticeably different.
Android /mobile tends to pick a faster quality setting than when you run the build on your PC so there might be lighting differences.
Vertex lighting is recommended for mobile because of this (its cheaper to do).
It would be nice to automatically switch shaders when pixel lighting is disabled but not sure there is.
