I noticed this tonight when pointing my phone camera at my PC. I’m not sure if it has to do with the camera switching lenses or what because I am using an iPhone XS Max so maybe it has something to do with going between the standard lens and the telephoto lens? Would love some info on this, I have attached a link to a video of what i’m talking about.
