Question Having issues with Lighting. Editor and Build not showing the same result

Hello everyone,

Would like to asked a few question about lighting. I have setup a 3D character in the scene and have setup a 8 point light for my character, 4 above and 4 below the character. so with this my character will light up evenly.

But right now my problem is in the Editor and camera view I can see that all of my 3D character light up and there's no shadow. But when I tried build it on mobile iOS and Android somehow my 3D character have some shadow issues. The place where is suppose to light up is dark.

Why is this happening.

Thank you.
