Mobile solution

Heres the solution for Nokia C6-00 Camera Switch and volume up and down control buttons that doesnt working. This solution may only works and can be applied if the switches assembly is okay and or already been replaced but still  it doesnt respond when being pressed.

The solution below shows the line paths of these said switches to the two EMI filter Ics which can be used to trace its lines paths or to determine which filter IC has to be checked or then replaced if  found damaged.
