The RPi camera uses a cable that looks nearly identical to a flat flex cable.
The regular RPi Camera connector.
The Pi Zero adapted version.
I have seen videos of people folding/creasing these types of cables. (Source) But I do not know if this is okay to do with the RPi Camera's cable. Could this do harm to the cable and cause it to not work or be unreliable?
The reason I need to fold/crease it is because I have a project in which a Pi Zero is almost touching the walls of it's casing, so the cable only has about 0.5cm of space between the Pi and the wall.
EDIT:
At about 1:50 in this video he states to not make kinks in the cable, but he does not provide any reason for this.
