Can I get some help with a touch key light problem?

Touch key light problem

I've bought an old galaxy s6 white from someone, background light of the touch keys doesn't light up only "back and multitasking" symbols, it also lights up area around these symbols, I can see it very clearly in the dark. This thing doesn't happen on my brother's S6 gold. So my question is: Is it normal on S6 white or my S6 has been replaced other glass?
Thank you!!

Re: Touch key light problem

I have a white S6 and when my touch keys light up they also have a glow around the symbols as well. My guess is just because of the color white. Its going to pass light through a little easier than black or gold.
