Preparing the new display

1. Not all available displays have the same features. If necessary, you’ll have to take some of the following parts from your old display before installing the new screen:
   • Earpiece mesh from the old screen; may have to be glued on (see figure 1)
   • Front camera bracket (see figure 2)
2. Check whether the PVC cover on the proximity sensor (see figure 3) is in its place (only for the black iPhone 4; if you’re installing a white display, you also have to put on this cover). If your screen no longer goes dark when you’re talking on the phone after this repair, you can get help here.
3. You can use a paintbrush or the laboratory spatula to remove the dust from the Home button. (See figure 4).
4. Pull the protective film off the back of the new LCD.
5. If the adhesive film next to the Home button and front camera is clean, you can continue to use it. Otherwise, pull it off.
