To Johnkustic: I am having the same problem - Front camera not working after replacing the screen on iphone 4s. Is it possible for me to send the phone to you so you could do that little soldering job?

You probably damaged your mother board. There is a little chip above Audio jack flex connector check if it still there if it is missing that is the reason for front camera not working.

You can create a little jumper to fix the problem. See this pic

Hope that helps.

so if i use a bit of solder to connect both these points up it will work again?? should i use anything that will connect these two points?

by Patrick Daly

Yes Patrick just join the two points with a little bit of solder and your camera will work again. I do it all the time for my customers.

John...please assist!! I have this exact problem. Front camera on my 4G not working, I check the board (which I bought yesterday) and sure enough, that little chip is missing. There is NO WAY I can solder this jumper - it's so small. Any suggestions?? Can you assist with repair?

Hi, Johnkustic, I am trying to help my friend to solve the same problem for the iPhone4. Before trying to solder the small jumper on the board, could you tell what's the jumper intended for? Is it bypass the control bus of the front camera? When the jumper is soldered, can the front camera come back alive? or the front camera is still not functioning but the phone will not screw up the camera application when flip the camera from back to front? Your kind help is highly appreciated. Thanks

Have checked the schematic of iPhone4, I found out that the small jumper is a ferrite beat F21, which introduce the 2.85V DC supply for front camera. It make sense to bridge it if the this component is missing, because no DC supply for the front camera, even the camera may powered from 1.8Vdc, but I don't know if it will be stable or not.

When you replaced the camera, did you disconnect the battery 1st? If not...disconnect battery for a couple minutes & restart phone.

My front facing camera was not workin on my jailbroken iphone 4. I disabled springtomize and then it was working so look in apps like ifile and springtomize to see if you disabled the front facing camera setting

There is a logic board issue whereby the camera, either front, or back camera is no longer recognized by the iphone 4. The only way to fix it, is to have the logic board component replaced. This service can be found on ebay.

1. Jailbreak your device

2. Download iFile

3. Go to System/library/CoreServices/SpringBoard.app/N90AP.plist

4. Set the value for front-facing-camera to false

5. Reboot

You will now not have the option to "accidentally" use the front facing camera.

Hi Patrick,

I see from your original post...you changed your display. So more than likely when you removed/installed the connectors at the top of board...you probably knocked a little chip off of it.

To test chip above audio jack connector, just solder across (bridge) both connections. If your camera works, just leave it that way. It will work fine.

Hallo i tried this yesterday to make a jumper between this two points and after that my front camera worked perfect but it stopped to make calls the carrier was gone and when i was trying to make a call to somebody his phone was ringing but my phone it was dead i didnt hear anything. After that i removed the bridge to see if this was the problem but the problem was still there and the front camera stopped again to work. After few hours the problem with calls stopped without to do something. Do you have hear this before? It happend beacause the jumper or is something else that just happend?

You probably damaged another component of Logic Board by keeping the solder gun on a spot too long.

I researched this to no end and I think finally I resolved it. YOU MUST replace the front lens from the old screen or it won/t work. The lens pushes the camera to make contact with the steel shield on the back of camera which then grounds it to the under side of board. With out the it, it becomes useless because it isn't grounded correctly. I used a small metal ground between the camera and it's metal bracket for the ground.
