We are due to see iOS 14.4 pretty soon, with the expected launch of the controversial tracking opt in message. But iOS 14.4 may also notify users if the camera used in the phone is supplied from a aftermarket source, i.e if the camera system has been replaced or repaired in a place where non genuine Apple components were used.

The following message may appear on the screen:

Unable to verify this iPhone has a genuine Apple camera.

This was retrieved by a MacRumors contributor who delved into the code of the latest iOS 14.4 beta and found this message and is ver similar to the messages the iPhone displays if it detects a non genuine Apple screen or battery was used too.
