Remove the three screws securing the Taptic Engine:

One 2.0 mm-long Y000 screw

One 1.6 mm-long Y000 screw

One 4.0 mm-long standoff screw

Standoff screws are best removed using a standoff screwdriver or 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.
