The OtterBox Defender Case has three layers: an outer, plastic holster, a rubber slipcover, and a hard plastic shell. Each of the individual layers is removable. To remove the plastic holster, the outermost layer, unclip each of the four corners one at a time. Next, peel the rubber slipcover away from the plastic casing. If you're struggling to get underneath the cover, undo the flap covering the charging port and pull the small tab of rubber away from the device. You will then be able to slide your finger underneath all edges. Finally, using the clips on the underside of the remaining plastic case, unclip the case's frame from the rear. These clips sit along both sides and the top and bottom of the phone. Once you release the clips, the frame and the back cover will separate from the phone.
