so i came home from school one day, i had it in the case with the protective screen still on caring for it like no other. i went to play rockband for an hour or so and come back to check my phone (which was laying on a dresser) i see this scratch type thing running across the screen. at first i thought it was just a piece of dog hair or something put i lifted the clear stuff and it was an actual giant scratch? but how did it scratch/crack? there's no cracks or anything anywhere else. ill get a pic soon if ones needed?
