Surface peeling around the lens border of iphone 12
I bought my iphone 12 on 9th April, 2021 from Israel. Currently I am in India. Form last few weeks I can see some white little marks around the lower lens border of my iphone. Initially I thought something got stuck there but with time marks are becoming prominent and looking like surface is peeling (Please check the image below). What should I do to fix this? Whether my warrently will cover to fix this issue? To make it clear, I didn't buy any additional warrenty coverage for my device.
Where I can fix this issue in the state of West Benga, India?
Please help with this. Thank you in advance.
iPhone 12, iOS 14
