Einleitung

Use this guide to replace the back cover adhesive by applying it to the back cover 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 the clear side matches the frame, follow this guide instead.

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

This guide is applicable for all Galaxy S21 devices.

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