i noticed i got what i think is a dust partical on my rear camera however you can't really notice it unless you look in direct light i'm tempted to give it in but honestly what stops me most is the fact that i got a pretty much near perfect screen since a lot of people on another thread on here is mentioning about yellow screens... however my question is if it's possible that if i was to go the genius bar to make an appointment show them this would they maybe be able to fix it there and i can still keep my phone without the exchange? so far other then that i have no issues at all... any advice will help thank you.
