If you need to replace neither the rear or front facing camera you can do this now.

To remove the front facing camera disconnect the camera from the board (marked in green). The connector is the same as the other connects on the mainboard.

To remove the rear facing camera disconnect the camera from the board (marked in red). The connector is the same as the other connects on the mainboard.

You will find the ear receiver on the second mid frame. I have marked it in red.
