Problem with moveable point light in mobile app

I try to make flashlight for my android project. I can’t use moveable spotlight, so I make a tube with pointlight inside. Everything looks good in editor, light goes only through the hole, but something strange happens on the phone. Light source completely ignores the tube. You can see this on screen. What can I do with it?
I made tube with inversed faces and double tube, but that gave nothing.

Unfortunately spotlight shadows isn’t supports on mobile too.
P.S Don’t know why, but there’s too many limitations in comparison with Unity :frowning:
