That camera needs high optic quality glass or plastic, be precisely aligned, then a microchip that can do 60fps or more or 10 bit then that chip also need software, calibration with sensor then they sell it to Apple. As a complete package. Then on top of that Apple adds another software and customisations. Same applies for displays. The 120 hz chip that drives Samsung displays is made by another company. Google it as IC 120 hz oled driver. That is a chip.Thats an interesting observation. So basically sony makes the sensors and LG packages the camera modules.
