My wife was saying this was happening to her phone last night while in the Apple camera app.yeh same! hmm yeah maybe we should I don’t think it should make those noises. But I think I’ll wait till the apparent fix next week with software
She wasn't at the time even aware of any of the 3rd party camera "issues".
I don't know if she ever tested it though...
But she only uses Instagram, and even then, she does not use the camera function through the app.
This is on her 14 PM. I don't notice anything out of the ordinary on my Pro.
