You will see an orange electronic ribbon cable running from the green board at the bottom of the phone, over the back of the screen and finally attached to a metal cover that hides the ear speaker.

To remove the metal cover from the speaker, first take a close look at how it is connected to the phone. There are two metal prongs that hold the cover in place.

Use the thin end of a tool, like a spudger, to gently depress the prongs and simultaneously lift the cover off of the speaker.
