My iPhone 6 camera protrudes slightly and so does my iPod touch 5th gen, but I don't worry about scratching my iPhone camera because I know it's coated in sapphire. Is the iPod touch protruding camera also sapphire? Or is it just the same glass as the screen?
The iPod touch 5 is older then the iPhone 6 (released with the iPhone 5) so no, it does not have a sapphire coating. However, it generally is durable enough for most things before it scratches.
