Introduction

Use this guide to replace the back cover adhesive by applying it to the frame first.

To determine where you first apply the adhesive, match the contours of the adhesive on the clear side with the back cover and the frame. If your adhesive strip matches the bottom cover, follow this guide instead.

The frame-first adhesive tends to have screw holes in the colored lining.

This guide is applicable for all Galaxy S20 devices.

    • Be very careful with this step, as misaligning the adhesive can cause it to peek out of the phone during reassembly, leading to an improper seal.

    • Carefully align the sticky side of the adhesive over the edges of the frame.

    • You can use the screw holes to help line up the adhesive.

    • This is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

    • Align the back cover with its original position on the frame.

    • Press down on the perimeter of the adhesive to bond the adhesive to the back cover.

    • To ensure a good seal, apply constant pressure to the back cover with a flat, heavy object. A hefty book works well.

    • If a substantial gap remains, try squeezing the gap with your fingers but don't force it. Pry the back cover off and check for any surface irregularities, such as unseated connectors or loose and jutting screws.
