I accidentally dropped my iPod on the floor 4 days ago, then when I looked the screen isn't broken but the inside of it was scratched. Like a green scratch. How do you fix it? If you can't, how do you prevent it from spreading? Cause the green scratch gets bigger every single day and I'm worried that it could spread around the whole screen. Any suggestions? I hope you can help me fix it, this is my only apple device.
