Last night when I reset my phone while the room was dark, I noticed I could see parts of the edges of the screen under what should be dark plastic around the transparent screen area (mostly on the left edge, close to the bottom). It seems parts of the plastic is thinner than others and is allowing some of the light from the screen edge to bleed through.

Again, it is mostly only noticeable is the room is truly dark and the screen is on the start up screen.

Does my phone have thin plastic or is this a common build issue?
