πŸ‘£Step-by-Step Guide: How to Remove the Back Cover of a Samsung S21 Plus Smartphone

Before starting the process, ensure you have a clean and well-lit workspace. Keep in mind that this guide is for informational purposes only, and any modifications made to your device may void the warranty. Proceed at your own risk.

πŸ› οΈEquipment Needed

1. A clean microfiber cloth or non-abrasive cloth
2. A plastic pry tool or a guitar pick
3. A hairdryer or a heat gun (optional)


1. Power off your Samsung S21 Plus before starting.
2. Perform this process at your own risk. Be cautious and patient to avoid damaging the device.
3. If your device is under warranty, removing the back cover may void it. Refer to the manufacturer or authorized service centers for assistance.
4. Do not apply excessive force when removing the back cover, as it may crack or break.

Step 1: Prepare the Device
Power off your Samsung S21 Plus smartphone by pressing and holding the power button until the power menu appears, then tap on "Power off" and confirm.

Step 2: Remove the SIM Card Tray
Locate the SIM card tray slot, which is usually on the top or side of the device (varies by model). Use the provided SIM ejection tool or a paperclip to gently push into the small hole until the tray pops out. Remove the SIM card tray and set it aside.

Step 3: Remove the Protective Case (if applicable)
If you have a protective case or cover on your Samsung S21 Plus smartphone, remove it before proceeding. This will provide better access to the back cover.

Step 4: Heat the Back Cover (optional)
If the back cover is firmly adhered, you can use a hairdryer or heat gun to apply gentle heat to soften the adhesive. Set the device to a low or medium heat setting, and hold it a few inches away from the back cover. Move the heat source evenly across the surface for about 1-2 minutes.

Step 5: Begin Prying the Back Cover
Insert a plastic pry tool or a guitar pick into the gap between the metal frame and the back cover, near one of the corners. Apply gentle pressure to create a small gap. It's essential to start at a corner, as it usually has the least adhesive.

Step 6: Slide the Pry Tool or Guitar Pick
Slide the pry tool or guitar pick along the edge of the device, working your way around to separate the back cover from the metal frame. As you progress, you may hear snapping sounds, which are the plastic clips releasing. Be careful not to insert the tool too far into the device, as it may damage internal components.

Step 7: Apply Heat (if needed)
If the back cover is not detaching easily, apply gentle heat again for a short duration to soften the adhesive. Be careful not to overheat the device or concentrate heat in one area for too long.

Step 8: Release the Remaining Clips
Continue sliding the pry tool or guitar pick along the remaining edges of the device until all the clips have been released. Be patient and cautious throughout the process to avoid damaging the clips or the back cover.

Step 9: Remove the Back Cover
Once all the clips have been released, carefully lift the back cover away from the device. Be mindful of any cables or connectors that may be attached to the cover. If you encounter resistance while lifting the cover, recheck if any clips or adhesive are still holding it in place and release them.

Step 10: Clean the Back Cover and Device
Use a clean microfiber cloth or a non-abrasive cloth to wipe away any dust, fingerprints, or debris from the back cover and the device.
