Messing with my 5s i discovered a small raised edge on the glass running down the left side of the phone and a little on the right. It is more noticeable at the top near the mute switch and volume buttons and as it runs down to the bottom less so. I compared this to my 5 which has no raised edge. Has to be a manufacturing flaw. The edge is enough that if I run my finger nail from the center of the glass to the edge my fingernail can catch and drag the phone. Anyone else experiencing this?
