Samsung Galaxy S8 Vibrator Motor Replacement - Samsung Galaxy S8

Step 1 | iOpener Heating

Any debris on the microwave floor may adhere to the iOpener.

Clean the microwave thoroughly before proceeding.

Position the iOpener in the center of the microwave.
For carousel microwaves, ensure the plate rotates freely to prevent overheating and damage to the iOpener.

Step 2

Be cautious not to overheat the iOpener during repair — overheating may cause damage.

Heat the iOpener in a microwave for 30 seconds, or until it's just too hot to touch.

Monitor and reheat as needed during repair; do not exceed 100°C (212°F).

If the iOpener appears swollen, do not handle it — inspect for swelling throughout the procedure.

Continue using a heated iOpener that's still too hot to touch; wait until it cools down before reheating again.

Step 3

Be extremely cautious when handling a heated iOpener.

Remove the iOpener from the microwave and hold by one of its flat ends to avoid direct contact with the hot center.
Use an oven mitt if necessary for added protection when handling the heated tool.

Step 4 | Alternate iOpener heating method

If no microwave is available, heating the iOpener requires caution.

Fill a pot or pan with enough water to fully submerge an iOpener.
Heat the water to a boil and then turn off the heat.
Submerge an iOpener for 2-3 minutes, ensuring it's completely covered.
Use tongs to carefully remove the heated iOpener from the water.
Dry the iOpener thoroughly with a towel before use.

When handling the hot iOpener, be careful not to touch any part except for the end tabs.

Reheating instructions: Boil water, turn off heat, and submerge iOpener for 2-3 minutes.

Step 5 | Back Glass Assembly

Opening your phone will compromise its waterproof seals.

Prepare replacement adhesive before proceeding or ensure liquid exposure is avoided during reassembly.
Heat an iOpener and apply it to a long edge of the S8 for about 2 minutes.
Reheat and reapply as necessary, following iOpener instructions to avoid overheating.

Alternatively, use a hair dryer, heat gun, or hot plate, but exercise caution to prevent overheat damage to OLED display or internal battery.

Carefully plan your prying approach while waiting for the adhesive to soften.

Step 6

Be cautious not to damage the rear case's adhesive layout.

Identify the thick and thin areas of adhesive on the rear case as shown in the first image.
Pry around the edge of the rear glass panel, avoiding thin areas near the fingerprint sensor.

Step 7

Position a suction cup near the heated edge, but avoid the curved part.

A cracked back cover can prevent the suction cup from sticking – use strong tape or superglue if necessary.

Lift the phone using the suction cup.
Insert an opening pick under the rear glass, pushing up due to its curved shape.

Step 8

Reheat and reapply the iOpener to soften the adhesive.

Hold the tool firmly in place within the glass.

Step 9

Slowly slide the opening pick down the side of the phone to separate the adhesive.

Go slowly to prevent the tool from slipping out of place.
If cutting becomes difficult, reheat and reapply the iOpener.

Step 10

Continue the heating and cutting process for the remaining sides.

Apply a new opening pick to each side before moving to the next.
This will help maintain access by preventing the adhesive from resealing.

Step 11

Do not open the phone any further if the fingerprint sensor cable is snagged or taut.

Disconnect the orange cable with a blue connector as you lift the rear glass.
Use opening picks to slice through remaining adhesive and open the phone slightly, but only if the cable has disconnected.

Carefully disconnect the connector with a spudger's point if necessary.

During reassembly, align the back cover so the cable connector lines up perfectly over its socket.
Use the flat end of your spudger to snap the connector into place by pressing straight down.

Remove the rear glass from the phone.

Step 12

Use tweezers to remove remaining adhesive from phone chassis.

Clean adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth.
Peel adhesive backing off new rear glass, align one edge against the phone chassis, and firmly press the glass onto the phone.

Before installing new adhesive, turn on your phone and test your repair to ensure proper function.

If desired, remove large chunks of old adhesive that may interfere with installation.
Apply heat and pressure to secure the back cover; note: it will not be waterproof but the glue should hold securely.

Step 13 | NFC Antenna and Charging Coil Assembly

Use a Phillips #000 screwdriver to remove eleven 3.7 mm screws.

Step 14

Remove the NFC antenna and charging coil assembly.

Step 15 | Loudspeaker Assembly

Remove three 3.7 mm Phillips #000 screws.

Step 16

Remove the loudspeaker assembly.

Step 17 | SIM Card

Insert a SIM card opening tool into the small hole on the left side of the top edge.

Press to eject the tray.
Remove the SIM card tray from the phone.

Ensure the SIM card is in the proper orientation when reinserting.

Step 18 | Battery Connector

Disconnect the battery connector using the flat end of a spudger.

Note: The battery remains in place during these steps.

Step 19 | Motherboard

Disconnect the sensor array connector with the flat end of a spudger.

Step 20

Disconnect the front-facing camera connector with the flat end of a spudger.

Step 21

Disconnect the display and digitizer connector with the flat end of a spudger.

Step 22

Use the point of a spudger to gently pry apart and disconnect the two antenna cables.

Step 23

Disconnect the antenna ribbon cable from the motherboard using the flat end of a spudger.

Step 24

Insert the flat end of a spudger under the motherboard.

Lift the motherboard slightly.
Disconnect it from the daughterboard.

Step 25

Disconnect the battery connector first if it was left connected.

Avoid damaging the battery connector while lifting out the motherboard.

Lift the motherboard out of the phone carefully.

Step 26 | Vibrator Motor

Use the flat end of a spudger to gently lift out the vibrator motor.
