Samsung Galaxy S8 Plus Screen Replacement - Samsung Galaxy S8 Plus

Step 1 | Back Glass

Opening your phone will compromise its waterproof seals.

Prepare a replacement adhesive before proceeding or take precautions against liquid exposure during reassembly.
Heat the back of the phone with an iOpener along the left edge for about two minutes to soften the adhesive.
Reheat and reapply the iOpener as needed until the phone is sufficiently warm. Follow the iOpener's instructions to avoid overheating.

Using a hair dryer, heat gun, or hot plate may cause heat damage to the OLED display and internal battery; exercise caution when applying heat.

Step 2

Risk of damage to internal components: avoid cutting too close to the fingerprint sensor flex cable.

Identify thick and thin sections of adhesive as seen from outside the phone.
Cut through adhesive in thick portions, following its layout.
Avoid slicing in area near fingerprint sensor flex cable.

Step 3

If the back cover is cracked, ensure a secure suction cup seal by applying strong tape or superglue.

Attach a suction cup to the back cover near the heated edge but avoid the curved glass portion.
Lift the left edge of the back cover with your suction cup, creating a small gap between it and the frame.
If necessary, reapply heat to soften the adhesive and try again; be cautious not to overheat an iOpener or its gel pack may burst.

Step 4

Risk of rear glass breakage if excessive force or metal tools are used.

Insert an opening pick carefully into the gap.
Optional: Add a few drops of isopropyl alcohol for weakened adhesive in following steps.

Step 5

Slide your opening pick along the left edge of the phone to slice through the adhesive securing the back cover.

Leaving the pick in place may be helpful to prevent re-adhesion of the separated glue.

Grab a second pick.
Proceed to the next step with both picks still inserted.

Step 6

Continue slicing along the bottom edge of the phone.

Reheat the back cover as needed to keep the glue from hardening.
The glued area is larger here, so insert your pick deeper into the phone to fully separate it.

It may help to leave one opening pick in place and grab another for the next step.

Step 7

Careful not to damage the flex cable leading to the fingerprint sensor.

Slice through remaining adhesive along top edge, being cautious of the flex cable.
Slice through remaining adhesive on right side.

Use the diagram in step 2 for guidance to ensure safe removal.

Step 8

Do not attempt to fully remove the back cover at this time.

Lift the back cover from its left edge and hinge it open slightly.

Step 9

Use the point of a spudger to carefully pry up and disconnect the fingerprint sensor flex cable.

Step 10

Rushing the reassembly process can damage the fingerprint sensor cable.

Angle the back cover until the cable connector aligns with its socket.
Use a flat spudger to press the connector straight down into place.
If possible, use your finger to snap the connector in (be gentle).

Do not force the connector into place or you may strain the cable.

Step 11

Remove the back cover.

To install a new back cover with adhesive:

Peel away remaining adhesive from phone chassis using tweezers.
Clean adhesion areas with high concentration isopropyl alcohol (at least 90%) and lint-free cloth.
Apply new adhesive backing to the rear glass, aligning one edge with phone chassis, then press firmly.

Do not power on your device until after testing it following reassembly.

Optional: Remove large chunks of old adhesive before reinstalling back cover without new adhesive.
(Note: This will compromise water resistance.)
Apply heat and pressure to secure the back cover.

Step 12 | Disconnecting the Samsung Galaxy S8+ Battery

Remove the eleven 3.7 mm Phillips screws from the wireless charging coil + antenna assembly.

If any screws are difficult to remove even when fully loosened, use tweezers to pull them out.

Step 13

Locate the wireless charging coil + antenna assembly and its securing plastic clips.

Pry up the plastic in the marked areas using a spudger to release the clips.

Step 14

Remove the wireless charging coil + antenna assembly.

Insert the top edge of the assembly into the phone's frame.
Gently press down on the rest of the assembly to snap it into place.

Step 15

Disconnect the battery connector with a spudger, prying it straight up from its socket.

Step 16 | Screen

Disconnect the display using a spudger by prying up its flex cable connector from the motherboard socket.

Optional: Press the phone's back cover into place temporarily to protect the motherboard and battery from accidental damage.

Step 17

Apply heat to the bottom edge of the display using a heat gun or hair dryer.

The adhesive holding the display may be stronger than the back cover's.
If needed, switch to a more powerful heat source to weaken the display's adhesive.

Do not apply excessive heat, as this can damage the display or other components.

Step 18

Press a suction cup into place near the bottom edge of the display if possible.

If the display is badly cracked, the suction cup may not stick.

Use strong tape to lift the display instead, or apply superglue to secure the suction cup in place and allow it to cure before proceeding.

Step 19

Hold the suction cup firmly and pull up on it.

Lift the display's lower edge until a small gap forms between it and the frame.
Insert an opening pick into the created gap.

Optional: Add a few drops of isopropyl alcohol to the gap for easier adhesive removal in subsequent steps, but be cautious as excessive liquid can cause damage.

Step 20

Position your opening pick at the bottom of the screen and gently slide it across, working to release the adhesive holding it in place.

Step 21

Leave the first pick in place.

Grasp a second pick.

Step 22

Reheat the iOpener and apply direct heat to the left edge of the display for a minimum of 2 minutes.

Step 23

Insert opening pick and pry adhesive on left side of display.

Step 24

Apply heat to the iPad screen's right side with a heat source for at least 2 minutes.

If using an iOpener, re-heat as needed following its instructions to avoid overheating and gel pack rupture.

Step 25

Insert the opening pick along the right edge of the display.

Pry gently to separate the adhesive at the display's right edge.
Be cautious near the flex cable, located below the midpoint on this side.

Step 26

Apply heat to the top edge of the screen for at least 2 minutes.

If using an iOpener, re-heat it as needed following the manufacturer's instructions to avoid overheating and rupture.

Step 27

Aggressive prying may damage front-facing sensors and speaker assembly.

Work your opening pick under the top edge of the display, gently separating adhesive underneath.
Pry carefully to avoid damaging components.
You can return to this section after loosening the rest of the display.

Step 28

Use picks to separate adhesive beneath display areas.

Be aware of the flex cable, located below right edge midpoint.

Pry near top edge with caution: avoid damaging front-facing sensors and earpiece speaker.

Step 29

Separate the left edge of the display completely from the frame.

Lift and release the left edge carefully, taking note of any potential obstructions.
The right edge may require extra care due to the presence of the display flex cable.

Step 30

Pass the flex cable through the display's frame hole.

This allows full separation of the right edge of the display.

Step 31

Remove the display.

Follow the link for a detailed screen adhesive application guide: https://example.com/screen-adhesive-guide

Remove all old adhesive from the frame, taking special care to remove small glass fragments.

Clean the adhesion areas with 90% isopropyl alcohol and a lint-free cloth or coffee filter. Swipe in one direction only.

Failure to do so may result in incorrect mounting and damage to the display.

If necessary, replace the frame if it is bent or remnants of glue/glass are left behind.

Apply custom-cut double-sided tape to the back of the new screen.
Carefully feed the display cable through the frame and align the screen.
Press the screen into place.
