This is the main camera for the iPhone 5s.
The 8 megapixel camera is capable of taking 1080p HD video.
Please Note: If you have a scratched lens in the rear case, this part will not solve your issue.
Using a pair of tweezers, flip the rubber camera cover out of its clip, and toward the outside of the rear case.
Do not attempt to fully remove this cover, it is attached to the rear case, and only needs to be flipped open, not removed.
Using a plastic opening tool, disconnect the rear-facing camera cable connector from the logic board.
Be careful to only pry up on the connector, not the socket itself.
Remove the rear-facing camera from the rear case.
During reassembly, ensure that the camera cable bends in a 'U' shape to slot in behind the logic board.
If the rubber camera bumper has shifted, be sure to replace it before reassembling your iPhone.
