I noticed some debris or dirt or something on my photos and had already disassembled the iphone 5s to clean but it didnt fix a particualr spot. I purchased a new rear camera to do the repairs myself.
Repair went smooth with the tools I had purchased from ifixit! Just take your time and go slow. Pay close attention on the orientation of the metal clip for the first connector. make sure to do a good cleaning once you have the unit open
Go slow and put the tiny screws in a safe location once you have them removed.
