Blue spots showing on screen when i turn my iphone 12 pro camera

Hey, i have bought this iphone 12 pro last year brand new. The issue now i am seeing is that whenever i turn my camera app on, there is these spots i see from 1x to2x zoom. As i zoom in more they disappear. Yes i have checked it in instagram and fb camera. It is still there. Before 1x zoom and after 2x there are no spots seen. Please do anyone else facing this problem. And can someone suggest what to do?

Thanks
