Mine didn't but it did peel up on me. I use a ton of cases so I'm assuming that one of them caught the side and caused it to lift.
One thing to note, the Otterbox version of a SP doesn't have a cut out for the front facing camera. At least on the three I have gotten (I got one with my Commuter and 2 with the Impact cases I bought).
While it looks a little weird because of it, it actually didn't make any difference in quality of the camera on the front. No glare or anything and the pictures it took looked fine. I don't use the useless facetime app but I did take a bunch of pictures with it and they looked fine.
