1, remove the two screws at the bottom with a Torx screwdriver.
2. When the suction cup opens the front screen (from the bottom, slowly open it to the top, because there is a line between the top of the screen and the motherboard in the machine) Note: No, no, no, you don't need to disassemble the line of the screen!
3. At this point, you can see the rear camera assembly (in the upper right corner inside the machine). (The last picture is for reference only, and no stitches are needed at all. At this time, you can gently pick up the camera module on the upper right with tweezers (I picked it up directly with my fingers).
This camera is not fixed with any screws. In fact, it is only placed in that position, and the pressure on the front panel is fixed. (Note that there is a small protrusion stuck in the upper right corner of the front screen panel, which is the key to fixing the camera. )
5. Gently pick up the camera with tweezers, clean the dust or traces with cotton swabs, and blow the camera to clean it.
I hope I can help you and hope to adopt it! ! !
