ok..i fugured out the cause for this.im posting it in case somebody needs it. there is only one light to light up all three buttons..all u have to do is centre the light in the place for all three buttons to light up equally.

Is this the case with Mi4 as well?
I have this problem since I replaced screen and thought I just broke buttons light. Is there a way to fix this without taking off screen?
