Gap between glass and plastic rim on 5s

My 5s is great with no issues. However I have noticed a tiny gap between the glass screen and the plastic band that goes round rhe screen. It's above the ear speaker. It's about 1cm long. It's covered by a case so can't see it. Is this something I should worry about. Thanks

You misunderstood. The gap is between the glass and the plastic rim not the metal bezel. It's as if it's come away slightly.
