Situation:

IPhone 6 front camera working normally, the rear camera not working, although replace with a new rear camera, it still not working.

What's the wrong with IPhone 6 rear camera?

Let's analyse as following:

First, remove the display assembly and take down the rear camera. Measure the rear camera power supply voltage. The power supply voltage value is normal.

Then, measure the resistance between rear camera connector and grounding. The resistance value of pin 30 is 303, which is abnormal. The reference resistance value of pin 30 should be 537 or so.

Pin 30 works as the activating signal of the flashlight. It is also connected with pin E3 of flashlight IC U1602 via FL2322 and C2300.

Take down the logic board. Then attach the logic board to PCB Holder. Then take down capacitor C2300 with Hot Air Gun at 320℃. Then measure the resistance between pin 30 and grounding again. The resistance value of pin 30 is 300, which is abnormal.

According to the analysis, we need to change the IC U1602.
