7) If there is a problem with the functionality of the CAMERA KEY, go through the following steps to fix it:
First check that the CAMERA KEY switch is working properly by pressing it halfway (focusing) and all the
way (taking a picture). If the CAMERA KEY switch is not working it has to be replaced. It is a level 2 part
and needs soldering.
8) Secondly, check that the CAMERA KEY is assembled firmly by pushing it outwards from the inside of
the BACK COVER.
