Why new photos can't be saved on my iPhone 6? A customers complained that. Now we need to check the iPhone, analysis the reasons and then solve this problem.
After checking, the iPhone 6 fault is sometimes the photos can not be
saved, but sometimes it's normal. It is found that the iPhone 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 12-1-1.
This screws column 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 screwd 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.
Scraping the lead to get rid
of the possibility of broken line.
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. After welding the jumper
wire by QUICK 861DW rework station, the flashing light E2 has a resistance value.
Finally, install the iPhone and test it, now the iPhone 6 can store new photos.!
