Introduction

Is the rear glass on your OnePlus 9 Pro cracked and shattered? If so, use this guide to remove and replace the glass on the back of your OnePlus 9 Pro.

Use caution during this guide since glass is always dangerous to deal with, especially when it is broken.

Adhesive is needed to put the back glass back on the phone. This phone is also water resistant and will only retain that water resistance if the adhesive is properly put down while repairing.

For your safety, discharge your battery below 25% before disassembling your phone.

This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

Unplug any chargers/peripheries and power off your phone.

Step 2

If the rear glass is cracked, be sure to tape over the glass panel before moving on.

Step 3

Use a hair dryer to lightly heat the perimeter of the rear glass.
Additionally, heat the top-right corner, as there is adhesive further inside of phone in that one spot.
Do not hold the hair dryer in one spot on the phone for too long to prevent damage to internal parts of the phone.

Step 4

Apply a suction handle as close to the bottom edge as possible.
Pull up on the suction handle with strong, steady force to create a gap between the glass and the frame.
If you have trouble creating a gap, apply more heat to further soften the adhesive.
Insert an opening pick into the gap.

Edit

Step 5

Slide the opening pick around the perimeter of the rear glass to slice the adhesive.
Insert additional opening picks as you slice the adhesive to prevent the adhesive from resealing.
If the adhesive becomes hard to cut, it has most likely cooled down. Use your hair dryer to reheat it.

Step 6

Carefully lift the rear glass up and off of the phone.
During reassembly secure the rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.
