Replacing the rear camera in your GSM or CDMA iPhone 4 is an easy Do-It-Yourself (DIY) repair, as long as you have the right tools and parts. We will show you a demonstration and explain the procedure to do that step by step. The camera of your iPhone will start working again. Even though, the GSM and CDMA variants are slightly different, this procedure will work for both. So follow this procedure to replace the camera of your iPhone 4.
DISCLAIMER: You are carrying out this procedure at your own risk. The Apple Bites would not be responsible if this procedure goes wrong or if some defect occurs in your iPhone 4.
Tools you need for this repair:
1. A GSM or CDMA iPhone 4 (obviously).
2. #00 Phillips screwdriver.
3. Pry tool or a spudger.
4. Security screwdriver (you would need it only if your iPhone has 5-point security screws in the dock connector).
Now we start the procedure of replacing camera in your iPhone 4.
(ii) Remove the back of your phone:
STEP 1 – First you should remove the bottom 2 dock connector screws in your iPhone 4. You can either use your #00 screwdriver or the five point depending on whether or not your iPhone 4 has security screws in the dock connector. Almost all newer devices have security screws.
STEP 2 – Slide the back upwards and lift it off gently.
STEP 3 – Set the back and 2-dock connector aside and keep them safely.
Just check if the lens of the back of your iPhone is not dirty or with scratches as this can also be a reason for bad photos that your camera is taking. You can try taking a photo without the back of your phone to check that. However, we assume that there is no problem with lens and the camera needs to be replaced.
(iii) Remove the battery:
STEP 1 – First, you need to remove the #00 screw holding the battery clip in place. Remove this screw located to the bottom left of the battery.
STEP 2 – The metal clip on the battery clips the battery in your iPhone 4 to the logic board. You need to pop this clip up with your plastic pry tool. Stick the end of your pry tool underneath the clip and gently pull upwards until it gets unfastened from the logic board.
STEP 3 – Do not use plastic pull tab to remove the battery. There is adhesive underneath the battery and the tab will normally just rip off the battery. You may bend the battery by this step. That is why, you should run your pry tool along the right side of the battery and break the adhesive that way. Once the battery is free from the adhesive, you can pull the battery out of the phone. There are no other connectors holding it in.
STEP 4 – GSM iPhone 4 users will notice a tiny grounding clip sitting underneath where you unscrewed the battery. You should set it aside for replacement during reassembly. This is a grounding clip for your antenna. You should keep in mind that you would need to put it back in place before reconnecting your battery. CDMA users will not see this as it is in a different location.
(iv) Remove the top logic board:
STEP 1 – There are 5 screws holding the logic board shield in place. The shield can be different, depending whether you have GSM or CDMA. However, the process is the same in both the cases. Remove the 5 screws holding it in place. You should remember which holes they came out of as the screws are different sizes. It is a good idea to keep them in the same order in which they come out.
STEP 2 – Now you have to remove the shield. Both models, whether GSM or CDMA, have a tiny clip built into the shield holding it in place. Pop it up with your pry tool. You should be able to slide the shield up fairly easily. While doing this, you should be careful that you do not bend it or break off a clip. The Verizon variant seats into the logic board with two tiny notches underneath the camera connection. When reassembling, you need to line up the two notches on the shield and it will slide into place easily. For the AT&T model, make sure that the clip is the first part you insert and it will line up again.
(v) Inserting new rear camera:
STEP 1 – Only one connector holds the camera to the logic board. You need to remove this cable by using your pry tool. Gently lift upwards and it will pop right off.
STEP 2 – Gently lift the camera out of your iPhone 4. You will notice a tiny tab seated underneath the LCD and digitizer cables to the right.
STEP 3 – To insert the new camera, slide the tabbed part underneath the two cables. After that, push down gently to seat the camera. Try not to touch the lens at all, while doing this.
STEP 4 – Fasten the cable to your logic board again.
Put all the screws back in their places while reassembling the parts (including the back) iPhone.
The camera in your iPhone 4 has been successfully replaced.
