Weird blemishes on photos taken from front facing camera on iPhone 16 Pro

Hi Richard, when I say after sunset I mean just as the sun has set. I’ve just gone out and took some pictures now at 19:44 with the sun pretty low and the rings are still there - but it’s still pretty bright right outside now. (When I said it’s after the sun’s gone down, I was basically ruling out the possibility of it being some kind of lens flare with the sun hitting the camera lens.)

Yes they’re always in the same spot and yes they are on opposite corners of the image. As I say, this is with the selfie camera which can only zoom in and out a tiny bit - but as I zoom out, you can see more of the circles - which would suggest if there’s something in the lens itself, it has to be pretty close to the outer edge. Here’s a picture I took just now - you can see the effect very faintly.

Here’s what it looks like as I zoom in and out while taking a photo with the selfie camera. I screen recorded the camera app while pressing to zoom in and out. This is taken around an hour before sunset so still pretty decent brightness outside.

YouTube downgraded the quality but hopefully you get the point - YouTube short of the blemishes while zooming
