An alert on my iPhone 12 says that there is a unknown part for my camera. There are no unknown parts I bought this directly from the Apple store. My camera appears to be functioning fine what do you recommend I do?

Click on the Get Support link at the top right of this page to contact Apple Support to resolve it.

It happens sometimes if it "thinks" that there was a new part that was installed but where there wasn't a proper system reset. I've heard of this happening when salvage parts were installed from another iPhone, where Apple obviously won't help out with the reset.]

With an original part where it's just gone haywire, you should be able to have it reset, regardless of whether or not it's still in warranty.
