Today's video is on the iPhone 12 and how Apple have made it impossible for repair companies to repair a broken camera thus forcing you to upgrade your phone once it's past it's warranty period. It's not just the camera, they stop you replacing other parts of the phone. Any attempt to do so will leave the phone unstable. People have purchased two identically iPhone 12's brand new, replace one part of the phone by swapping the hardware, and the phone refused to work. This has caused anger, especially among the repair community. The author of this video does a lot of videos on these topics, and is also an Apple repair engineer.
