Bad speakerphone? No speakerphone audio? This may be the part you need!
This part is for speakerphone and audio output.
Sometimes a part can become clogged with dust or be damaged in a liquid spill.
Use the tip of a spudger to pry the antenna cable up from its socket on the logic board.
Remove the following Phillips #000 screws:
One 2.9 mm screw
One 1.5 mm screw
One 3.6 mm screw
Use the point of a spudger to gently pry between the speaker and the rear case, lifting the speaker enough to grab with your fingers.
Do not attempt to pry the speaker entirely out of the case, you may break plastic tabs holding the speaker in place.
Swivel the speaker downwards and toward the left of the phone to free the upper tab from underneath the logic board.
Slide the speaker up and to the right to free the left-hand tab from under the home button cable connector.
Remove the speaker from the iPhone.
