These steps show how to remove the phone's front case. This allows access to many of the components located on the outer face of the phone.
Remove the four grey plugs using either tweezers or a push pin.
Remove the four screws that are now exposed using a Phillips #00 screwdriver.
Once all the screws have been removed, use a plastic opener tool to pry the case from the rest of the phone.
Insert the opener tool into the seem between the case and the phone. Apply pressure to separate the two pieces.
Do this across the entire length of the seem until the case is no longer attached to the phone.
The case can now be removed and the interior of the front is accessible.
