I seem to have the same issue, however it’s not really possible for me to work on a real device all the time. I kind of need emulators to test compatibility.
Using the lighting material at all causes the issue, even if you don’t set any additional parameters.
terrainMaterial = new Material(assetManager, "Common/MatDefs/Light/Lighting.j3md");
terrainMaterial.setColor("Diffuse", new ColorRGBA(96f / 255, 128f / 255, 56f / 255, 1.0f));
terrainMaterial.setBoolean("UseMaterialColors", true);
results in the following output:
