First, the display shield is connected to the display frame plated area (screw boss area),
and then to the PWB through the two top screws. The grounding of the display shield
and frame impact the radiation performance of the phone. If the screws are loose,
tighten them. If the screw bosses are stripped, replace the chassis. If the screws are
missing, install new ones.
If the plated area of the display frame is cracked or the metal plating is peeled off, then
the grounding of the display shield and frame will not be guaranteed. If this is the case,
replace the frame.
