    Hello, I got to do 6s after flooding with the torn camera slot and the lack of several elements around the socket. After filling the gaps under the microscope, the back camera has a black background and the flashlight does not work ... i.e. When turning on the flashlight, the icon turns gray, ie it turns on but does not shine. The front camera is working properly.

    I changed the camera - no result.


    I found some walkthroughs on the internet:

    I've bridged the U3200 like a photo.

    I checked all the passages around the socket like on a photo.

    On FL3200 I have 4.1va should be probably 2.8v?

    How did you make the bridge on the U3200, why are you expecting an 2.8V voltage on the FL3200? U3200 is the LDO of the rear camera, you made a bridge between the input and the output of this circuit, so you have there VCC_MAIN or voltage from the main power branch. You must think and not follow the walkthroughs blindly, the paws fall: /

    I'm not a service technician :) I do it hobbyally for fun and joy if it works :) can not switching from a different U3200 disc change anything here?

    The fact that you do it in a hobby does not absolve you from thinking, following the walkthroughs from the internet, you can beat the phone.

    Inserting the U3200 chip will probably restore the voltage of 2.85V but I do not know if the camera survived as you gave it 4.1V ;)

    For the future, all the elements on the disc are needed and have been placed on it for some purpose, wiring any one is usually a bad idea. The wire can be used to repair interrupted connections between elements.

    The camera will survive, after a few days discoloration will begin, the photos will be noisy and eventually it will fall.
    The battery will also be discharged sooner, the camera will take non-stop current.
    The bridge can only be made for diagnosis, it is not a repair!
    Unfortunately, solucje z neta is a pathology: /

    Ok, gentlemen. On Wednesday, the U3200 will be soldered in its place. I have several cameras so after checking I check on another one which I have not tested in this phone yet. If you say you can do it for the test and I still do not work, the problem is somewhere else.

    Gentlemen, the camera works!

    U3200 transplanted from a different plate, in addition, even at a higher magnification of the microscope, I found cold solder on one element.

    Regarding the operation of the cameras themselves after taking the jumper on the U3200 - all the cameras I tested with this jumper still work.

    Hi, I do not remember anymore because some time has passed :) from what I remember in the small piece near the connector was a problem.
