White Spots

[slowlx]

I recently noticed two white spots on my screen. They're in the lower left hand side of the screen, strange but u can only see them say when the screen is white itself, u can make them out perfectly. Just wondering if anyone else had something like this come up on their phone. Doesnt really bother me but I just dont want something bad to happen to the screen itself. Im kinda debating whether or not to take it into sprint, what do u guys think?
