Dropped my iPhone 5 on the floor from my desk (nudged it over at night, didn't even see it fall to try to catch it or break the fall). Now when i fire up the camera there is a strange artefact on the top left of the screen. It shows up in the app as well as in photos taken. This only happens with the rear facing camera, which was closer to the point of impact. The phone itself just got a little nick, i wasn't expecting any internal damage. Here is a sample photo and a close up of the artefact. What do you think it is and what should i do? Sadly, i live in greece and there are no apple stores here, trying to return or getting the phone fixed will probably mean they'll have to take it off me for some time and i'm not sure i can be phone-less for any length of time. Thanks for any help!!! PS. If i don't focus on it, it doesn't show in the image, here's a sample (it should be in the top left here).
