Introduction

Use this guide to remove and replace a broken or defective front camera in your Xiaomi Mi 9.

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

What you need

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.

Secure a suction handle to the lower edge of the rear glass, as close to the edge as possible.
If the phone's rear glass is cracked, the suction handle may not stick. 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.
Insert an opening pick into the gap.
If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Slide the opening pick to the bottom right corner of the phone.

Insert a second opening pick and slide it to the bottom left corner to cut the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Insert a third opening pick at the bottom left corner.
Start to slide the opening pick from the bottom left corner along the side of the Xiaomi Mi 9 to cut the adhesive.
Be aware of the rear cameras and only insert the tip of the opening pick. As the adhesive cools down it gets harder to cut. If necessary use your iOpener to reheat it.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Insert a fourth opening pick under the top left corner of the rear glass.
Slide the opening pick along the top to cut the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Carefully lift the rear glass and remove it.
Before installing new adhesive and reassembly, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

Remove the ten Phillips #00 screws (3 mm length) that secure the motherboard cover.
There might be tamper proof sticker on some of the screws.

Insert an opening pick at the top right corner of the motherboard cover.
Twist the opening pick sideways to pry up and slightly lift the motherboard cover.
