Take Apart & Replace Screen – Samsung Galaxy S20 Screen Repair

Hey there! In this video, I will guide you through the process of replacing the screen assembly on your Samsung Galaxy S20 Ultra. If you’ve damaged your device, don’t worry—I’ll show you how to fix it. Before we get started, you’ll need a few tools, and there’s a link down below in the description to this premium toolset so you can perform this repair yourself.

Step 1: Power Off the Device

The first step is to power off your Samsung Galaxy S20 Ultra completely. Once it’s off, you’ll need to heat the back glass cover to loosen the adhesive holding it in place. You can use a hairdryer, heat gun, or a hot plate. If you’re using a hairdryer or heat gun, make sure to move it around consistently and never stay in the same spot for too long to avoid burning the phone’s internals. Heat the back cover until it’s too hot to touch for more than a second.

Step 2: Remove the Back Cover

Wear rubber gloves to avoid burns. Use a suction cup from the toolkit and place it near the charging port at the bottom of the back cover. Gently pull up until you see a slight opening. Insert a plastic pry tool or a business card folded in half into the opening to start removing the adhesive. If the phone cools down, reheat it before continuing. Once the bottom part of the back cover starts lifting, you can pull it off completely, revealing the phone’s internal components.

Step 3: Remove Internal Components

With the back cover off, you’ll see the wireless charging pad, loudspeaker, and other components. Start by removing all screws holding down the covers. Disconnect the cable for the wireless charging pad and peel it back. Remove the loudspeaker and any other screws securing internal parts. Next, disconnect the battery flex cable to stop electricity flow and remove the screen cable.

Step 4: Remove the Motherboard and Screen Assembly

There are two ways to replace the screen: ordering just the glass screen assembly or the entire screen assembly with the frame. If you have the glass screen assembly, heat the screen edges, remove the old screen, and replace it with the new one. For the entire assembly, you’ll need to take the phone apart completely.

Disconnect the flex cables, remove the screws, and lift out the motherboard. Carefully remove smaller components like the front camera, ear speaker, and antennas. Use a plastic pry tool to lift the battery, applying heat if necessary to loosen the adhesive.

Step 5: Reassemble the Phone

To reassemble, start with the antennas, then the volume and power button rockers. Place the small components back into their positions, then the motherboard. Connect the flex cables, but leave the battery flex cable for last. Reattach the metal brackets and screws, securing everything in place. Reconnect the screen cable and then the battery flex cable.

Step 6: Attach the Back Cover

Inspect the back cover and the phone’s frame for any debris or leftover adhesive. Position the back cover correctly and apply pressure to secure it. Ensure the adhesive adheres well to the frame.
