Remove the six screws securing the earpiece speaker:

One 2.4 mm‑long Phillips screw

Three 1.3 mm‑long Phillips screws

One 1.6 mm‑long Phillips screw

One 3.3 mm‑long standoff screw

Standoff screws are best removed using a dedicated standoff driver or driver bit. In a pinch, a small flathead screwdriver will do the job—but use extra caution to ensure it doesn't slip and damage surrounding components.
