Galaxy S20 Screen and Battery Assembly Replacement

Insert a SIM card eject tool, bit, or a straightened paperclip into the hole on the SIM tray located at the top edge of the phone next to the plastic antenna band.

• If the tool is inserted into the other hole, it will not cause damage as the microphone and ingress gasket are out of harm's way.
• Press in firmly to eject the tray.

• Remove the SIM card tray.
• The SIM card will fall out.

When reinserting, ensure proper orientation to avoid damaging the SIM card tray.

• Apply heat to the bottom edge of the back cover using an iOpener for two minutes.
• Alternatively, use a hair dryer, heat gun, or hot plate, but be cautious not to overheat the device.
• The display and internal battery are susceptible to heat damage.

Apply excessive force with the opening pick to avoid damaging the back cover.

• Attach a suction cup as close to the center of the bottom edge as possible.
• If your display is badly cracked, apply clear packing tape for better adhesion.

If necessary, use superglue to secure the suction cup on broken screens.

• Pull the suction cup with strong force to create a gap between the back cover and frame.
• Insert an opening pick into the gap carefully.

Reheat and reapply suction multiple times if needed due to tight tolerances.

• Apply more heat and try again if creating a gap proves difficult.

Risk of damage if the curved edge is cut.

• Slide a pick along the bottom edge, moving it back and forth.
• Avoid cutting near the corners where the glass is curved to prevent cracking.

Avoid overheating the device — display and internal battery are prone to heat damage.

• Apply a heated iOpener or use an alternative heat source (hair dryer, heat gun, hot plate) for two minutes along the right edge of the back cover.

Apply a suction cup to the phone's right edge, near center.

• Pull on the suction cup with strong force to create a gap between the back cover and frame.
• Insert an opening pick into the gap, tilting it downward for full insertion underneath the back cover.

Slide the pick along the right phone edge to separate the back cover's adhesive.

• Leave the pick under the glass near the top of the device to prevent resealing.
• If other picks are released, set them aside and do not use them again.

Apply a iOpener to the top edge of the back cover and heat it for 2 minutes.

Be careful not to crack the curved glass near the corners of the back cover.

• Start by sliding a pick from the right edge around the top right corner.
• Continue slicing along the top edge to the top left corner, separating the adhesive completely.
• If it gets stuck, stop and reapply heat before continuing.

Slowly lift the back cover and use opening picks to cut through any remaining adhesive.

• Remove the back cover.

Before reassembling, power on your phone and test all functions; then completely shut it down.

• Use a pair of tweezers or your fingers to remove any remaining adhesive chunks.
• If needed, apply heat for easier separation.
• If using custom-cut adhesives, refer to the specific guide.
• If using double-sided tape, follow the relevant guide.
