A screw‑driven camshaft in the bottom left corner pushes the back cover away from the phone, creating a gap to begin separating the cover.
With the back cover facing up, use a T3 Torx screwdriver to turn the screw in the bottom edge counterclockwise until the back cover pops up.

Before separating the back cover, note the following:
There's a seam just under the back cover panel. Don't insert your tool here.
Insert your tool completely under the back cover, so it's between the frame and the underside of the back cover.
Insert an opening pick under the bottom left corner of the back cover and slide it along the bottom edge to release the clips and separate the adhesive.
You should feel and hear the back cover clips release. If you don't, insert the pick deeper and try again.

During reassembly:
Now is a good time to test your phone before sealing it up. Power it on and check that it works. Power it back down before you continue reassembly.
If you're installing a new back cover:
Make sure you remove all liners from the underside.
Use the flat end of a spudger to press the small cable above the wireless charging coil into place over its alignment posts.
Place the back cover onto the frame and firmly squeeze around the perimeter to reengage all the clips.
