Got my iphone 5 last october so it's been more than a year now. But the screen looks like I took sandpaper and started rubbing. I take care of my phone too, no screen protector but I do use a case that extends past the front so screen would never touch a table even when it's face down. I'm guessing this is caused by sand/dust particles in my pocket? Either way this is supposed to be gorilla glass but it sure doesn't look like it. Is anyone else seeing a more than expected amount of scratches on their iP5 screen?
