Step-by-Step Guide to Removing the Back Cover
Now that you’re well-prepared, let’s go through the steps for removing your Samsung S21’s back cover.
Step 1: Apply Heat
The adhesive used to secure the back cover is strong, and applying heat will soften it.

Gently pull up on the suction cup while simultaneously inserting a plastic opening tool into the small gap created between the back cover and the frame.
2. Work Your Way Around
With the plastic opening tool, slide it cautiously along the edges of the back cover. Be gentle to avoid cracking the glass.
Step 3: Pry Open the Cover
Continue working your way around the edges until you feel the adhesive loosening.
Once you’ve made sufficient separation, gently lift the back cover away from the device. If you encounter resistance, reapply heat and try again.
Step 4: Disconnect the Battery (if necessary)
Should your goal include battery replacement, now is the time to disconnect it.
- Locate the battery connector on the motherboard.
- Use the tweezers to carefully lift the connector away from the socket.
Step 5: Clean or Replace Components
With the back cover removed, you can now clean any dust, debris, or fingerprints from the internal components.
If you’re replacing the battery, carefully lift the old battery out and insert the new one, making sure it aligns with the connectors accurately.
Step 6: Reassemble Your Device
Once you’ve completed your tasks, it’s time to put everything back together.
To reattach the back cover, align it with the sides of the phone and gently press it down until you feel it securely snap back into place. Make sure the adhesive re-establishes its bond. In case the adhesive has weakened, consider using double-sided adhesive strips for a secure hold.

What tools do I need to remove the back cover of the Samsung S21?
To safely remove the back cover of your Samsung S21, you will need a few essential tools. A heat gun or a hairdryer is recommended for softening the adhesive that holds the back cover in place. Additionally, a plastic prying tool or a guitar pick will help you gently lift the cover without damaging the phone. A set of small screwdrivers, specifically a Torx or Phillips screwdriver, may also be necessary for accessing screws if your model has any.
Before starting the process, ensure you are in a clean, static-free environment to prevent any damage to the internal components. It’s also wise to have a microfiber cloth on hand to protect the phone’s surface during the removal process. Taking these precautions will make the removal smoother and minimize the risk of accidental damage.
Is it safe to remove the back cover myself?
Removing the back cover of your Samsung S21 yourself can be safe if you follow the instructions carefully and take the necessary precautions. By using the right tools and techniques, you can minimize the risk of damaging your device. However, there is always some inherent risk involved in disassembling electronic devices, so you must be cautious and patient throughout the process.
If you’re unsure or uncomfortable with working on your phone, consider seeking professional assistance from a technician or a repair shop. They have the experience and tools to safely remove the back cover without causing any harm to the device, ensuring that it remains in good working order.
What should I do if the adhesive is too strong?
If you find that the adhesive on your Samsung S21’s back cover is particularly strong, it’s crucial to proceed carefully to avoid damaging the device. Start by applying gentle heat to soften the adhesive further. Using a heat gun or hairdryer, warm up the edges of the back cover for about 30 seconds, ensuring that you don’t overheat any internal components. Once warmed, try using your plastic prying tool gently to leverage the cover off.
If the adhesive still proves to be too stubborn, you can repeat the heating process. In some cases, applying a small amount of isopropyl alcohol around the seams can help dissolve the adhesive. Remember, take your time and don’t rush the process to avoid cracking the glass back.
Will I void my warranty by removing the back cover?
Removing the back cover of your Samsung S21 might void your warranty, as most manufacturers have specific policies regarding device repairs and modifications. If you attempt to open the phone and damage any internal components in the process, it could lead to denial of warranty claims by Samsung. Thus, it’s essential to be aware of your warranty conditions before proceeding with any DIY repair.
If your device is still under warranty and you require repairs, consider reaching out to an authorized service center or Samsung directly. This way, you’ll ensure that your warranty remains intact and that any repairs are done using genuine parts, which can also help maintain device performance.
How can I reapply a new back cover once it’s removed?
After removing the back cover of your Samsung S21, you’ll need to ensure that the surface is free from any old adhesive and dirt for a proper seal upon reinstallation. Use an adhesive remover or isopropyl alcohol to clean the edges of both the back cover and the phone chassis thoroughly. Be precise during this step, as any leftover adhesive could inhibit the new adhesive from bonding effectively.
Once cleaned, you can apply new adhesive strips recommended for smartphone back covers. Align the back cover carefully and press it down firmly once positioned. Allow the adhesive to cure as per the manufacturer’s instructions to ensure a lasting seal. Keeping the phone flat and undisturbed during this period will help maintain an even bond.
What are the risks of removing the back cover myself?
When removing the back cover of your Samsung S21, there are several risks involved if not done correctly. First, there is the possibility of damaging the back cover itself, especially if it is made of glass. Cracks or chips can occur, which may necessitate a full replacement. Additionally, if excessive force is used during the removal process it can lead to damage to the internal components, such as the battery or circuitry.
Another potential risk is voiding your warranty, as previously mentioned. If any damage occurs while you are attempting the repair, the manufacturer may refuse to cover future repairs. Finally, working with small components can be tricky, as losing tiny screws or damaging connectors can complicate the reassembly process. Thus, if you are inexperienced, it is advisable to seek professional help.
