Safety Keep in mind these important safety measures before you start:

Electrostatic Discharge: Electrostatic discharge can cause malfunctions in delicate electronic parts.

• Wear an anti-static wrist strap and work on a surface free of static electricity.
• Be sure to power down your phone entirely before beginning any repair.
• Avoid misplacing any screws or other tiny parts by keeping a record of them.
• To avoid additional damage, handle the screen and interior components with care.

Top-Notch Equipment: No fix job is complete without first acquiring the proper equipment. Do not use too much force, as this can cause screws to strip or fragile components to break.

The Things You’ll Need 

• Stainless steel precision screwdriver set with Philips head and Pentalobe bits for fastening the rear cover. You should definitely get a kit that is made specifically for fixing mobile phones. 
• Use the suction cup to lift the screen securely. 
• The screen and frame can be separated with plastic pry tools or cards. To keep the item in pristine condition, stay away from metal objects. 
• Make sure you get a compatible and high-quality replacement screen for your new Samsung Galaxy S21. Visit mrfixelectronics.com to view the Samsung Galaxy S21 demo.
• Use a hair dryer or heat gun to loosen the adhesive that is keeping the screen and rear cover in place.
• To cut through the glue, use a thin plastic sheet or playing card.
• Isopropyl Alcohol (IPA): For removing previous adhesive remains. To fasten the replacement screen, you’ll need adhesive strips or BGA rework tape. (Adhesive is already applied to several screens). 
• Surface: It is critical to have a tidy, well-lit work area.

Setting Up for the Maintenance Time Required

• To power off your Samsung Galaxy S21, you must turn it off entirely.
• To remove the SIM card, simply eject the tray housing it.

Get Your Workspace Ready

• Make sure you have enough light and a surface that won’t attract dust or other particles.
• If you can, make a copy of all of your phone’s data before continuing.
• The first step, which should take about ten to fifteen minutes, is to remove the back cover.
• Heat the Back Cover: For one or two minutes, carefully heat the area around the cover’s edges using a hair dryer or heat gun. A softer adhesive will result from this. Make sure not to let the gadget get too hot.

• Make a Hole: Separate the Back Cover from the Frame by using the suction cup to make a tiny hole.
• Carefully slide a thin plastic sheet or playing card around the edges of the back cover to slice through the adhesive. Insert the card into the gap and repeat the process. Heat again if necessary.
• After you’ve cut the glue, carefully remove the back cover from the phone.

Uninstalling the Previous Screen

• To remove the mid-frame from the phone, find the screws and loosen them.
• Carefully separate the mid-frame from the rest of the frame.
• To avoid short circuits, unplug the battery connector before continuing.
• Once again, use heat to weaken the glue by gently heating the screen’s edges.
• Screen Lifting: Carefully raise the screen using the suction cup. Carefully glide a tiny plastic tool over the borders of the gap to cut through the remaining glue after inserting it.
• Removing the Flex Cables: Take care when removing the flex cables that attach the screen to the motherboard. Be careful with these connectors because they are often fragile.
• Take Care to Remove the Screen: Gently prise off the broken screen.

Get the Frame Ready 

• Get Rid of Old Adhesive: Gently wipe the frame off with a gentle cloth or plastic tool dipped in isopropyl alcohol to remove any lingering adhesive or broken glass.
• Make sure the frame is dust-and debris-free by giving it a good cleaning.
• It is important to inspect the connectors on the motherboard to make sure they are clean and in good condition.

Setting Up the Updated Interface 

• Carefully attach the new screen’s flex cables to their respective motherboard connectors. Make sure they’re sitting down safely.
• Reconnect the battery and turn on the device for a short while to check the new screen. Make that the screen is working properly, the touch functions, and the brightness. After checking that everything is working, turn off the device and remove the battery once more.
• The next step is to attach the adhesive by using fresh adhesive strips or BGA rework tape on the frame. Refer to the adhesive’s packaging for more instructions.
• Welcome to the installation screen! Press the replacement screen firmly into place after carefully aligning it with the frame.

Assemble

• Screw the Mid-Frame Back on: Gently screw the Mid-Frame back on.
• Make sure the battery connector is back in the battery.
• Before reattaching the rear cover, make sure it is in the correct position relative to the frame and apply heat to its edges. Squeeze it shut tightly.
• Keep the rear cover in place while the glue sets by securing it with clips or tape.
• Insert the SIM card tray to reinsert the SIM card.

Finalization and Testing 

• Launch: Launch your Samsung Galaxy S21 and give the new screen a good test. Make sure everything is working properly by testing the screen, touch sensitivity, brightness, and other features.
• Clear the Area: Remove any clutter or shattered glass from your work area.

The two most important things you can do when replacing a screen are to be patient and precise. Take your time and make sure you check each step twice because rushing can cause problems.

Even with the most meticulously crafted instructions, we understand that unforeseen problems can sometimes arise during a repair like this. The world of delicate electronics is often unpredictable, and despite your best efforts, you might encounter a snag. Perhaps a flex cable connector proves more fragile than you anticipated, requiring an extra touch of finesse. Or maybe a stubborn adhesive patch refuses to yield, clinging stubbornly to the frame. Perhaps a tiny screw is proving difficult to remove without stripping it, or a hidden component is causing unexpected resistance. These are just a few examples of the challenges that can emerge, even when following a detailed guide.
