iPhone 6S camera function unavailable—Here is the best solution

As we know, if your iPhone camera function unavailable, then you can't use it to take photos or videos, you will get angry about it. So, it's important to know its solution. The following contents will share best solution to fix iPhone 6S rear or front camera not working problems.

Open the WUXINJI to check iPhone circuit diagram, and we will know iPhone camera working circuit principle.

1. Solution for Rear Camera

There are three circuits supply power to iPhone camera:

One is 1.2V PP1V2_CAMERA from the power supply IC, the 1.2V power supply was sent to rear camera interface J3200 through inductor FL3201, if the voltage is not sent to the iPhone 6s rear camera interface, it is generally caused by FL3201 corrosion, use jumper wire to do short connection will solve the problem.

The second is 1.8V from the IC power supply, 1.8V power supply was sent to FL3220 rear camera interface through inductor FL3220, and inductor 3220 is easy to get corrosion damage so that 1.8V is not able to be sent to rear camera interface, use jumper wire to do short connection will solve the problem.

The last one is 2.85V which is supplied by U3200, the U3200 output voltage 2.85V was sent to rear camera interface through inductor FL3202, the rear camera fault is mostly caused by U3200 damage so that 2.85V is not able to be supplied to rear camera, the 2.85V voltage is not able to be tested by Digital Multimeter until there is resistance C3200 when taking photos. It's not easy to measure because of narrow place, so we can connect an enameled wire on capacitor C3200 for convenient measurement. Turn on the camera and test it immediately. If it is a good handset, it can measure 2. 85V voltage, if the 2.85V voltage is not measured when the camera is turned on, it indicates that U3200 is damaged. This situation can be also solved by phone repair jumper wire short connection.

2. Solution for Front Camera

If the front camera now working well, check iPhone flash IC to see whether it is fine. If it is damaged, you need to remove it, and then replace the new one.

And you need to check FL3100 FL3102 FL3104 short connection , if it is damaged, you need remove the iPhone 6S power iC, and then re-install it. If it still not working, then you need replace the new iPhone power IC.

At last, assemble the iPhone, get into IOS to test camera function.
