Back Glass Removal for Samsung Galaxy S21 FE Screen Replacement

Replacing the screen of a Samsung Galaxy S21 FE requires the careful removal of the back glass. This process involves several steps that must be followed precisely to ensure a successful screen replacement. Here’s a simplified version of the back glass removal process:

1. Start by powering off the device and removing the SIM card tray.
2. Heat the back glass using a heat gun or hairdryer set to low heat. This will soften the adhesive holding the glass in place.
3. Use a suction cup to lift the back glass from one corner. If the glass doesn’t come off easily, apply more heat to loosen the adhesive.
4. Once the glass is lifted, insert a plastic pry tool or a thin guitar pick between the glass and the frame. Slowly slide the tool around the edges to separate the adhesive.
5. Be careful not to apply too much force, as it can crack or damage the glass.
6. Continue sliding the tool around all four sides until the glass is completely separated from the frame.
7. Once the back glass is removed, set it aside for later reinstallation.

Remember to be patient and gentle during the back glass removal process. Taking your time and following these steps will help prevent any damage to the device or the back glass itself.

Now that you have successfully removed the back glass, you can proceed with the next steps in the screen replacement process.

Step 5: Detaching the Screen

Once the internal components are disconnected and the battery is removed, you can proceed to detach the faulty screen from the device.

Start by heating the edges of the screen to soften the adhesive. Then, use a prying tool to carefully separate the screen from the frame. Work your way around the edges, gently releasing the adhesive until the screen is fully detached.
