Missing Logic Board Back Camera Resistors/Capacitors
My friend's iPhone 4S Sprint model was recently repaired, and everything worked except the back camera. The phone will turn on normally and take pictures with the front camera, but switching to the back camera will cause it to freeze. Under closer inspection, I saw two missing components (Capacitors or resistors) near the back camera module. If possible, can any of you link me to a schematic or identify the missing components?
Here's a picture of the logic board with the damaged areas circled (might need to zoom in)
Es esta una buena pregunta?

Hello Guchi,
Great done with your work!
I have worked with iPhones for a few years now but I have never tried to microsolder before(but I want to try it)! Because I have the same problem as you have had with the iPhone 4S camera.
Did you just jump into it or have you worked with this before?
Do you also buy your tools for microsoldering in www.mouser.com? And is it possible for you to help me with the tools I need for this repair?

Hi Nea, The soldering Iron I used was a Weller TC201T bought off amazon. Any soldering iron should work as long as it has a needle-like tip (very thin and able to get to the solder pads without hitting other electronics)
I just jumped into this repair without previous practice, but I already had skills in soldering. If you doubt yourself, I suggest finding an old circuit board you don't mind destroying and desoldering and resoldering components.
Best of luck to you!
