After doing some additional research, I found many people having the same issue, that is possibly caused by heating, resulting in the coating not sticking correctly. There is also the assumption that the protective coating was never removed when manufacturing/assembly. I noticed that with slight pressure with just my fingernail on the front camera , same thing happens.. the coating scratches. And btw (for who thinks this is the cause) having the phone in your pocket has zero effect on this issue. I baby my phone , and always have a case on it, and would never put in anything else. Glad there is a simple fix, by removing the coating. However, a good idea would be to purchase a lens protector from slickwrapes just in case.
