Follow these 8 steps to complete your repair
Prepare the Device
Power off the Galaxy Z Fold 4 5G completely. Remove the SIM card tray using the SIM eject tool. This ensures the device is completely off and ready for repair.
Heat the Adhesive
Use a heat gun or hair dryer to gently warm the edges of the screen. This will soften the adhesive holding the screen in place. Move the heat source in a circular motion to avoid overheating any single area.
Lift the Screen
Place a suction cup near the edge of the screen and gently pull to create a small gap. Insert a plastic opening tool into the gap and carefully work your way around the edges to release the adhesive. Be patient and avoid using excessive force.
Disconnect the Display Cables
Once the screen is loose, carefully lift it to reveal the internal connectors. Use a spudger to disconnect the display cables from the motherboard. Note their positions for reassembly.
Remove the Old Screen
With the cables disconnected, you can completely remove the old screen. Clean any remaining adhesive from the frame using isopropyl alcohol and a microfiber cloth.
Install the New Screen
Align the new screen with the device. Reconnect the display cables by gently pressing them into their respective connectors. Ensure they are securely fastened to prevent display issues.
Secure the New Screen
Apply new adhesive strips around the frame. Carefully position the new screen and press it into place, ensuring it is securely attached without gaps.
Reassemble the Device
Reinsert the SIM card tray. Power on the device to test the new screen functionality. Check for touch responsiveness and display clarity.
