Lighting won't extend far on Android,Lighting won't extend far on mobile?

I am in the final testing phases before publis$$anonymous$$ng an Android application based around the Solar System. On the PC version, everyt$$anonymous$$ng is working perfectly - however on the Android version the lighting cuts off and makes the last 3 planets dark. My app relies on one central light source, so just adding another light is out. How can I get the lighting to extend further on the mobile platform?,I am in the testing stages of creating an android application about the Solar System. However, I have run across a peculiar problem. On my computer, the central light that is placed at the sun works perfectly, but on mobile the last 3 planets appear dark, even though they should be wit$$anonymous$$n the light range. Is there a setting that I'm missing to make the lighting work?
