Why Photos Cannot be Saved on iPhone 6 According to the last repairman's description, the iPhone 6 fault is sometimes the photos can not be saved, but sometimes it's normal. After checking, it is found that the camera can be saved now, so it's necessary to wait and observe again.
In the evening, we start disassembling to inspect what is the fault, the iPhone 6 motherboard has never been repaired, but the screw column is damaged, as shown in picture 1-1.
This screwdriver has a flashing light on the back of the camera. According to our repair experience, it is known that photos cannot be saved should be the iPhone flash IC problem. Will it be caused by screwdriver column? So after measuring the camera, the EN signal was found to be in a normal state, and would it be a semi - connected state? After scraping, it is found that this line is nearly disconnected. Is it the problem here? The photo is really not saved after installing to test. Connect the line, the fault finally comes out. Next, removing the flash IC off and cleaning the glue of the weld plate, then we start to measure the resistance, he E2 pin of the flash lamp is found to
have no resistance. This is the I2C bus that connects the iPhone 6 CPU with the rear camera and the flash IC. The details are shown in WUXINJI schematic diagram. Picture 1-2~3.
Scraping the lead to get rid of the possibility of broken line. Picture 1-4.
The camera can get the resistance and get the exclusion of CPU false welding, it should be disconnected line problem in the plate. The solution is to connect jumper wire from the E2 pin of the flash IC to the rear camera socket FL2329. As shown in Picture 1-5.
After welding the jumper wire, the flashing light E2 has a resistance value, install the flash lamp IC back, fault is solved now!
