Carefully remove the iPhone logic board, and then put it on the WL Aluminum Alloy Pad. Measure the ground resistance for iPhone front camera socket J4503 by Fluke 15B+ Digital Multimeter, the data tested is normal. And then measure the iPhone front camera power supply, the data tested also is normal. However, when we measure the I2C bus, we find the voltage for I2C_NH_SCL_CONN only have 0.62V, which is abnormal.
