A good way to fix the iPhone 7 Plus front camera
Recently, some users have reported that the iPhone 7 Plus camera sometimes cannot be used normally. We also encountered such a situation. Our client sent us an iPhone 7 Plus, he reflects that the front camera of his iPhone 7 Plus can't work normally, but the rear camera, flash and other functions are all normal.How to repair it?
If your cell phone is also in the same situation, you should first test it before it is repaired. The following is the repair steps.
1. Enter in to the system to have a test. Use iPhone 7 Plus opening tool kit to disassemble the mobile phone and remove the motherboard to test. We observed the repair traces of front camera J4503 base. It means the iPhone 7 Plus was repaired before. As shown in picture.
2. There is no any problem when we use Fluke digital multimeter to measure the ground value, when measure the voltage of the 2 groups of I2C that were repaired: (R4810) I2C_NH_SCL_CONN and (4811) I2C_NH_SDA_CONN, we found R4811 resistance has no voltage, but it has value when trigger. The circuit diagram we can check on WUXINJI dongle is as shown in picture.
3. Now we can judge that R4811 is damaged.Then we remove the incoming panel and replace the two pull-up resistors.
