If your Samsung Galaxy S20 Ultra 5G has a cracked screen or shows signs of damage, replacing the display yourself is a viable option. This in-depth guide will walk you through the entire process, step by step, ensuring you have all the necessary tools, parts, and instructions to successfully replace your phone’s display. Replacing your Samsung Galaxy S20 Ultra 5G display on your own can save you time and money while also giving you a sense of accomplishment.

Tools and Materials You’ll Need

Before you begin, it’s crucial to gather all the tools and materials required for the repair. Having everything on hand will streamline the process and reduce the risk of errors. Here’s what you’ll need:

• iOpener: A tool designed to safely apply heat, allowing you to open adhesive seals without damaging the device.
• Suction Handle: Essential for pulling up the glass and creating an initial gap between the phone’s back cover and frame.
• iFixit Opening Picks: Used to slice through adhesive and pry open the device.
• Spudger: A versatile tool for prying and disconnecting small components inside your phone.
• Tweezers: For handling small parts like screws and connectors.
• Phillips 00 Screwdriver: Specifically for removing the small screws securing internal components.
• High Concentration Isopropyl Alcohol (over 90%): For cleaning residual adhesive and preparing surfaces for reassembly.
• Replacement Display: The new screen that will replace your damaged one.
• Adhesive: To secure the new display and back cover once the repair is complete.
• Magnetic Mat: To keep track of screws and components, ensuring nothing is lost during the repair.

Important Safety Precautions

Before starting the repair, ensure your phone’s battery is drained below 25%. This reduces the risk of fire in the event of accidental battery damage. If your battery is swollen, do not proceed with heating your phone. Instead, follow appropriate safety precautions and consider seeking professional help. Instructions for handling a swollen battery can be found in the guide linked at the end of this article.

Step-by-Step Guide to Replacing Your Samsung Galaxy S20 Ultra 5G Display

Step 1: Heat the Back Cover

The first step in replacing your Samsung Galaxy S20 Ultra 5G display is to remove the back cover. To do this:

1. Heat an iOpener by following the manufacturer’s instructions.
2. Place the heated iOpener on the bottom edge of your phone’s back cover for about two minutes. This softens the adhesive, making it easier to remove the cover.

Step 2: Create a Gap Between the Cover and the Frame

Once the adhesive is softened:

1. Attach a suction handle to the heated area of the back cover.
2. Gently but firmly pull up on the suction handle to create a small gap between the back cover and the frame of the phone.

Step 3: Insert an Opening Pick

To prevent the adhesive from re-sealing:

1. Insert an iFixit opening pick into the gap you created with the suction handle.
2. You may need to reapply heat and attempt this multiple times if the gap is too small or the adhesive is particularly strong.

Step 4: Cut Through the Adhesive

With the opening pick in place:

1. Carefully slide the pick along the bottom edge of the phone, cutting through the adhesive that holds the back cover in place.
2. Repeat this process for the left, right, and top edges of the phone. Pay special attention to the corners, as they are more prone to cracking.

Step 5: Remove the Back Cover

After all the adhesive has been cut:

1. Gently lift and remove the back cover. Set it aside in a safe place.

Step 6: Disconnect Internal Components

With the back cover removed, you’ll need to disconnect several internal components:

1. Use the spudger to disconnect the wireless charging coil connector.
2. Gently peel the coil away from the phone.
3. Remove the screws securing the motherboard bracket using the Phillips 00 screwdriver.
4. Disconnect the battery cable, display cable, and any other connectors that are attached to the motherboard.

Step 7: Remove the Display

The next step is to remove the damaged display:

1. Heat the top edge of the display using the iOpener, just as you did with the back cover.
2. Attach a suction handle to the heated area of the display.
3. Insert an opening pick into the gap created by the suction handle and begin slicing through the adhesive.
4. To help loosen the adhesive further, apply a small amount of isopropyl alcohol around the edges of the screen.
5. Carefully pry up the display using the spudger, taking care not to damage any internal components. Once the adhesive is sufficiently loosened, remove the display completely.

Step 8: Prepare for the New Display

Before installing the new display:

1. Thoroughly clean all old adhesive from the phone’s frame using isopropyl alcohol and a lint-free cloth.
2. Apply new adhesive strips to the phone’s frame, ensuring that they align with the edges.

Step 9: Insert the New Display Cable

To install the new display:

1. Carefully thread the new display cable through the designated slot in the phone’s frame.
2. Lay the new display in place on the phone’s frame, but do not remove the adhesive liner yet.

Step 10: Test the New Display

Before sealing everything back up:

1. Reconnect the display cable and the battery cable.
2. Power on the phone to test the new display. Make sure the screen functions correctly, with no dead pixels, discoloration, or touch sensitivity issues.
3. If the display works properly, power off the phone, disconnect the cables again, and remove the adhesive liner from the new display.

Step 11: Install the New Display

With the adhesive liner removed:

1. Reconnect the display and battery cables to the motherboard.
2. Secure the loudspeaker and motherboard bracket with the screws you removed earlier.
3. Reconnect the wireless charging coil and press it firmly in place.

Step 12: Seal the Back Cover

To complete the repair:

1. Apply new adhesive strips to the back cover of the phone.
2. Press the back cover firmly onto the phone’s frame, ensuring that it is properly aligned.
3. To ensure a tight seal, place a weight on the phone and leave it for at least 30 minutes.
