I'm actually surprised that nobody tried to poke into those lines yet and built something similar to https://hackaday.com/2021/07/05/how-to-drive-smartphone-scre... but for the camera.

Actually, since that project above links to a iPhone 4 screen as an example, I'd perhaps err into probing for MIPI signals on an iPhone 6S camera first, perhaps using sth like https://hackaday.com/2018/11/29/mipi-csi-2-implementation-in...?

This post is fascinating, btw: https://www.circuitvalley.com/2020/01/spi-mipi-bridge-fpga-v...
