Introduction

Use this guide to remove or replace the rear glass in the Xiaomi Mi 9.

You’ll need replacement adhesive to reattach components when reassembling the device.

  1. Before you begin, switch off your phone.

    • Apply a heated iOpener to the rear glass to loosen the adhesive beneath the edges. Apply the iOpener for at least two minutes.

Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed. Lift the rear glass with the suction handle to create a gap between the glass and the frame.
