Samsung Galaxy S25+ Back Cover Replacement
If the back cover is bulging, it could be a swollen battery; take necessary precautions.
- Acquire a new back cover and replacement back cover adhesive.
- Follow this guide to replace the cracked or broken back cover.
Step 1 | Safety precautions
Never start repairs with a fully charged battery — risk of fire.
- Allow Galaxy's battery to drain below 25% before proceeding.
- Unplug all cables from the phone.
- Power button, hold side key and volume down button, select Power off.
Step 2 | Cracked glass preparation
Apply packing tape strips over cracked back glass to contain it and aid removal.
- Cover the entire crack with non-overlapping tape for maximum protection.
- Ensure a single strip of tape spans the bottom edge, large enough for a suction cup to fit.
- Avoid applying tape to the phone's frame.
Wear safety glasses to protect your eyes from flying glass debris during the repair process.
Step 3 | Heat the back cover
Apply heat to the back cover using an iOpener, a hair dryer, or a heat gun.
- Lay the iOpener on the bottom edge of the back cover for two minutes.
- Follow the linked instructions carefully when using a heat gun to avoid damaging the display and/or battery.
Improper use of a heat gun can destroy the display and/or battery.
Step 4 | Adhesive information
Use the provided picture as a reference for separating the back cover's adhesive.
- The back cover is secured with adhesive around the frame's perimeter.
- Insert your tool under the cover, but only near the cameras, to avoid damaging them.
Step 5 | Apply a suction handle
Position the suction handle on the center of the back cover's bottom edge, as close to the edge as you can.
Step 6 | Insert an opening pick
Be cautious when handling a potentially hot device.
- Pull up on the suction handle with strong, steady force to create a gap between the back cover and frame.
- Hold the phone down or stabilize the frame with your free hand while keeping the fingers of your lifting hand engaged.
- Insert the tip of an opening pick into the formed gap.
Step 7 | Separate the bottom edge adhesive
Apply heat if the back cover feels stuck.
- Use an opening pick along the bottom edge to separate the adhesive.
Step 8 | Separate the right edge adhesive
Insert an opening pick at the bottom right corner.
- Gently slide it upwards along the right edge.
- The goal is to separate the adhesive completely.
Step 9 | Separate the top edge adhesive
Insert opening pick a few millimeters near cameras.
- Slide opening pick around top right corner.
- Continue along top edge to separate adhesive.
Step 10 | Separate the left edge adhesive
Insert the opening pick into the top left corner of the device and slide it down the left edge.
- Apply gentle pressure to pry the adhesive loose.
- Continue working the opening pick along the left edge until the adhesive is fully separated.
Step 11 | Remove the back cover
- Use the suction handle to lift and remove the back cover.
- If still stuck, go around perimeter with an opening pick and separate remaining adhesive.
Power on phone and test all functions before resealing. Power down completely after testing.
- Inspect rear cameras for smudges and clean with a lint-free cloth if necessary.
- Apply replacement back cover adhesive to either the frame or back cover, using cutouts and contours for best alignment.
