My phone was brand new when I bought it and it has NEVER been serviced. I’m getting the “unknown camera” notification and my camera is now not working properly. This is absolutely not ok. What can be done about this?
iPhone 12 Pro Max, iOS 16
Hello,
An Unknown Part 
message appears if the part installation is incomplete or if the part:
For display and battery, you might find an additional message that says "Apple has updated the device information for this iPhone." This means that Apple has updated the device information maintained for this iPhone for service needs, safety analysis, and to improve future products.
These messages don't affect your ability to use your iPhone, its battery, display, or camera.
One of these messages might appear in the Parts and Service History section: Face ID Issue Detected, Cellular Issue Detected, Ultra Wideband Issue Detected, or Apple Pay Issue Detected.

With iOS versions earlier than iOS 15.2, you can check only if a replacement part is identified as an Unknown Part.
Information about parts and service history is collected by Apple and stored as part of the device information maintained for your iPhone. This information is used for service needs, safety analysis, and to improve future products.
Parts and service history is shown only if your iPhone has had a part replaced or if a part isn't functioning as expected. If a part has been serviced more than once, only the most recent service will appear.
iPhone parts and service history is linked to the serial number of your iPhone. If your iPhone has been repaired in a way that generates a new serial number, you'll find only the parts and service history that's associated with the new serial number.
Hope I Helped😊
