This was super simple. My camera was not focusing after a previous company replaced it due to a faulty flash. I decided to take things into my own hands...no pun intended.
The instructions are super simple and easy to follow. Be aware of the loose clip under the connector - mine flew out - and I was worried I wouldn't figure out how to get it back in.
I also had to use a #0 screwdriver...#00 was too large.
I couldn't get the battery out...so, I was just super careful that the phone was off, and remained off during the repair.
Out with the defective camera...in with the functioning camera...replaced a couple of screws and the battery connector. Tested the camera prior to replacing everything.
Thank you ifixit!
