Front (secondary) camera troubleshooting

Context
First verify the problem by testing the camera with a camera application. In case of image quality (IQ)
related problems:
● Check the problem with a reference phone to see that it actually is a problem and not some
misunderstanding of the camera capabilities.
Check that nothing is blocking the camera's field of view, such as a broken camera window, dirt, or a
●
window protective foil still attached.
If the camera does not start, locate the problem using camera tests in the Care suite. Other checks without
going under the cans:
● Visually inspect component/PWB damages
● Check the camera lines that can be measured with a multi meter:
●
SDA (I2C3) line from the R2311 on the main PWB
● SCL (I2C3) line from the R2310 on the main PWB
If the camera failure is located to the camera module, change the main PWB.
