My phone, which is about two years old at this point, has a very scratched lens cover. Think the purple coating or whatever it is isn't really there anymore. I don't know if it affects image quality, but right now I'm affected with a persistent blurring/haziness at the left side of the image (right side of the lens when viewed from the phone's rear). Also, a visibly dark spot is now noticeable in the image too, at the bottom left corner (I cannot find a corresponding spot on the rear lens cover). I'm wondering is there's any way to restore the image quality - and, no, it's not dirty - no amount of wiping fixes the haze at the left size.
