the gap is seen very slightly and pushed with nail
u cant see in the pic .
try to find it at the left side center and beside volume keys
its ok to have that gap. The area above volume keys is weak spot in locking of gorrila glass. it's a design flaw the thin strip of plastic
created due to hole for volume buttons is weak and bends easily causing glass to slip. in new pieces that area is held with some kind of adhesive tape inside.
