Samsung Galaxy S20 Ultra Screen and Battery Assembly Replacement

Risk of damage to SIM card or tray if incorrect insertion occurs.

• Insert a SIM card eject tool, butterfly tool bit, or a straightened paperclip into the top hole on the SIM tray.
• Press firmly to eject the tray.

Incorrect insertion will not damage microphone or ingress gasket, but try again if unsuccessful.

• Remove the SIM card tray.

• The SIM card will fall out easily.

• If replacing, ensure correct orientation to avoid damage.

• Inspect the thin rubber gasket around the SIM tray for signs of damage or absence; replace if necessary to prevent water and dust ingress damaging internal components.

Unplug your phone and power it off.

• Heat an iOpener for two minutes and apply it to the back cover's bottom edge.
• Alternative methods: Use a hair dryer, heat gun, or hot plate, but be cautious not to overheat the phone.

The display and internal battery are susceptible to heat damage if overheated.

Apply a suction cup to the phone's back, as close to the center of the bottom edge as possible.

• If the back cover is cracked, apply clear packing tape for better adhesion or use strong tape instead.
• Alternatively, superglue the suction cup directly onto the broken cover if necessary.

Pull on the suction cup with steady force to create a gap between the back cover and frame.

• Insert an opening pick into the created gap.
• If unsuccessful, reapply heat with the iOpener and try again, potentially repeating this process multiple times due to tight tolerances.

Do not apply excessive force with the pick, as it may crack the back cover glass.

Risk of damage if adhesive is cut too close to curved edges.

• Slide the pick along the bottom edge, slicing through the adhesive.
• Avoid cutting near corners where glass curves.
• Leave the pick in place to prevent resealing of adhesive.

Apply heat from an iOpener to the left edge of the back cover for 2 minutes.

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

• Pull on the suction cup with strong, steady force until a gap forms between the back cover and frame.
• Insert an opening pick into the gap, aiming for the curved edge of the glass.

Due to tight tolerances, you may need multiple attempts. Excessive force can crack the glass.

• If trouble persists, apply more heat and try again.
• Alternatively, add a few drops of high-concentration (over 90%) isopropyl alcohol into the seam to loosen the adhesive.

Avoid applying excessive force with the pick to prevent cracking the back cover glass.

Insert the pick under the glass's edge, then tilt it downward and push in further.

• Continue until the back cover's adhesive is fully separated.

Position the pick at the bottom edge of the phone, carefully prying the back cover away from the frame.

Ensure the pick remains under the left edge of the glass near the device's bottom to prevent re-adhesion.

Careful not to crack the glass when navigating around the volume and power buttons.

• Insert a pick under the center of the left edge of the back cover.
• Slowly slide the pick towards the top of the device to separate the back cover's adhesive.
• Leave the pick in place near the top, under the left edge of the glass, to prevent resealing.

Be cautious not to overheat the phone when using a hair dryer, heat gun, or hot plate.

• Apply a heated iOpener to the right edge of the back cover for two minutes.
• Alternatively, use a hair dryer, heat gun, or hot plate but ensure not to apply excessive heat that could damage the display or internal battery.

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

• Pull 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.

• Slide the pick down towards the bottom edge of the phone.
• This will separate the back cover's adhesive.

• Leave the pick under the right edge of the glass near the bottom to prevent resealing.

Insert a pick under the right center edge of the back cover.

• Slide the pick towards the top of the device to separate the adhesive.
• If the bottom picks release, set them aside – they won't reseal later.

Place a heated iOpener on the top edge of the back cover for 2 minutes.

Be gentle when handling the curved glass edges 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 separate the adhesive completely.

If the slicing becomes difficult, stop and reapply heat before proceeding to avoid damaging the back cover.

Lift the back cover slowly.

Use opening picks to slice any remaining adhesive.

Remove the back cover.

• During reassembly, power on your phone and test all functions before sealing it up.
• Remove any adhesive chunks with a pair of tweezers or your fingers.
• If having trouble separating the adhesive, apply heat.

If using Samsung custom-cut adhesives, follow the provided guide for specific instructions.

For double-sided tape, refer to a dedicated guide for proper application and removal procedures.
