INTRODUCTION

Use this guide to replace a cracked or broken display on your Samsung Galaxy S8.

Note: This guide instructs you to replace only the display while leaving the original frame,motherboard, and battery in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure—transplantingyour phone's internals and installing a new battery. Make sure you have the correct part beforestarting this guide.

This guide involves removing the rear glass cover, you will need replacement adhesive to reattachthe back cover to the phone. If your replacement screen does not come with adhesive, you will needto use tape to secure it as well.

If the frame is damaged or bent, it's important to replace it, or else the new screen may not mountcorrectly and can suffer damage from uneven pressure.

The process of separating the display from the frame usually destroys the display, so don't followthis guide unless you intend to replace the display.

TOOLS:iOpener (1)Suction Handle (1)iFixit Opening Picks set of 6 (1)Spudger (1)Plastic Cards (1)Tweezers (1)Phillips #00 Screwdriver (1)

PARTS:Galaxy S8 Screen (1)Galaxy S8 Screen Assembly (1)Galaxy S8 Display Adhesive Strips (1)Galaxy S8 Display Heat Dissipation

Sticker (1)Galaxy S8 Midframe (1)Galaxy S8 Rear Cover Adhesive (1)Tesa 61395 Tape (1)

Thin, high-bond tape is required if thereplacement part does not come withadhesive.




Step 1 — iOpener Heating

We recommend that you clean your microwave before proceeding, as any nasty gunk on thebottom may end up stuck to the iOpener.

Place the iOpener in the center of the microwave.

For carousel microwaves: Make sure the plate spins freely. If your iOpener gets stuck, it mayoverheat and burn.




Step 2

Heat the iOpener for thirtyseconds.

Throughout the repair procedure, asthe iOpener cools, reheat it in themicrowave for an additional thirtyseconds at a time.

Be careful not to overheat theiOpener during the repair.Overheating may cause the iOpenerto burst.

Never touch the iOpener if it appearsswollen.

If the iOpener is still too hot in themiddle to touch, continue using itwhile waiting for it to cool downsome more before reheating. Aproperly heated iOpener should staywarm for up to 10 minutes.




Step 3

Remove the iOpener from themicrowave, holding it by one of thetwo flat ends to avoid the hot center.

The iOpener will be very hot, so becareful when handling it. Use anoven mitt if necessary.




Step 4 — Back Glass Assembly

Opening your phone willcompromise its waterproof seals.Have replacement adhesive readybefore you proceed, or take care toavoid liquid exposure if youreassemble your phone withoutreplacing the adhesive.

Heat an iOpener and apply it to along edge of the S8 for about 2minutes.

You may need to reheat andreapply the iOpener several timesto get the phone warm enough.Follow the iOpener instructions toavoid overheating.

A hair dryer, heat gun, or hot platemay also be used, but be careful notto overheat the phone—the OLEDdisplay and internal battery are bothsusceptible to heat damage.

As you're waiting for the adhesive tosoften, move on and read thefollowing step to get an idea ofwhere to pry.

Step 5

In the following steps you will be cutting through the adhesive around the edge of the rear glasspanel.

The adhesive on the rear case is laid out as seen in the first image.

The prying pattern as seen from the outside of the phone is as follows:

Thick portions of adhesive

Thin areas of adhesive

Avoid prying here, to protect the fingerprint sensor.




Step 6

Once the back panel is warm to the touch, apply a suction cup as close to the heated edge of thephone as you can while avoiding the curved edge.

The suction cup will not make a good seal on the curved portion of the glass.

If the phone's back cover is cracked, the suction cup may not stick. Try lifting it with strong tape,or superglue the suction cup in place and allow it to cure so you can proceed.

Lift on the suction cup, and insert a halberd spudger, or opening pick, under the rear glass.

Due to the curved glass, you will be pushing up, rather than inserting parallel to the plane of thephone.

Step 7

Once you have the tool firmlyinserted into the glass, reheat andreapply the iOpener to soften theadhesive.

Step 8

Slide an opening pick or the blade of a Halberd spudger down the side of the phone, separatingthe adhesive.

Go slowly so that the tool doesn't slip out of the seam. If cutting becomes difficult, reheat andreapply the iOpener.





Step 9

Repeat the previous heating and cutting procedure for the remaining three sides of the phone.

Leave an opening pick on each side as you continue to the next to prevent the adhesive fromresealing.




Step 10

The fingerprint sensor cable connects the phone to the rear glass near the main camera. Thecable is very short and should disconnect as the rear glass is removed.

As you lift the glass, peek in to be sure the orange cable with a blue connector has disconnected.

Use the opening picks to slice through any remaining adhesive and open the phone slightly.

If the fingerprint sensor cable seems snagged or stays taut do not open the phone any further.Disconnect the connector with the point of a spudger before proceeding.

During reassembly, in order to reconnect the fingerprint sensor cable, first angle the back coverinto position until the cable connector lines up perfectly over its socket. Then, use the flat end ofyour spudger to gently snap the connector into place by pressing it straight down.

Remove the glass from the phone.




Step 11

To install a new back cover:Use tweezers to peel away anyremaining adhesive from thephone's chassis. Then clean theadhesion areas with highconcentration isopropyl alcohol(at least 90%) and a lint-free clothto prep the surface for the newadhesive.

Peel the adhesive backing off ofthe new rear glass, carefully lineup one edge of the glass againstthe phone chassis, and firmlypress the glass onto the phone.

Follow this guide to reinstall the oldback cover, or to install a back coverwithout pre-installed adhesive.

Be sure to turn on your phoneand test your repair beforeinstalling new adhesive andresealing the phone.

If desired, you may reinstall the backcover without replacing theadhesive. Remove any large chunksof adhesive that might prevent theback cover from sitting down flush.After installation, heat the backcover and apply pressure to secureit. It won't be waterproof, but theglue is usually more than strongenough to hold.

Step 13

Remove the NFC antenna and charging coil assembly.

Step 14 — Battery Connector

Use the flat end of a spudger to disconnect the battery connector.

Although the battery is not shown in the next steps, there is no need to remove it for this guide.Just disconnect the battery and you're good to go.




Step 15 — Screen

Use the flat end of a spudger to disconnect the display and digitizer connector.

Step 16

Heat an iOpener and apply it to oneof the long edges of the S8 for about2 minutes.

You may need to reheat andreapply the iOpener several timesto get the phone warm enough.Follow the iOpener instructions toavoid overheating.





Step 17

Once the screen is warm to thetouch, apply a suction cup as closeto the heated edge of the phone asyou can while avoiding the curvededge.

The suction cup will not make agood seal on the curved portionof the glass.

If the phone's screen is cracked,the suction cup may not stick. Trylifting it with strong tape, orsuperglue the suction cup in placeand allow it to cure so you canproceed.

Lift on the suction cup, and insert ahalberd spudger, or opening pick,under the display assembly.

Due to the curved glass, you willbe pushing up, rather thaninserting parallel to the plane ofthe phone.

Step 18

Once you have the tool firmlyinserted into the glass, reheat andreapply the iOpener to soften theadhesive.





Step 19

Slide an opening pick or the blade of a Halberd spudger down the side of the phone, separatingthe adhesive.

Go slowly so that the tool doesn't slip out of the seam. If cutting becomes too difficult, reheat andreapply the iOpener.

The screen's flex cable is located just below the midpoint on this side, and may interfere with yourcutting tool.




Step 20

Repeat the previous heating and cutting procedure for the remaining three sides of the phone.

Leave an opening pick on each side as you continue to the next to prevent the adhesive fromresealing.

When inserting the opening picks into the side of the phone, insert a long edge of the openingpick, instead of a point, to avoid putting extra stress on the screen.

Use a little extra caution when prying near the top edge so as not to damage the front-facingsensors and earpiece speaker.




Step 21

Use a plastic card to pry the screen away from the midframe.

Check the back of the phone and note which side of the phone has the display and digitizerconnector. Pry on the opposite side of the phone from the connector—the connector will act as ahinge.

Step 22

Carefully lift the screen assembly away from the midframe, gently pulling the display connectorthrough the hole in the midframe.

Remove the screen assembly.




After reapplying adhesive, follow these instructions in reverse order to reassemble your device.

Step 23

Follow this link for a detailed screenadhesive application guide.

Before installing a new display, it'svery important to remove all tracesof the old adhesive from the frame,while taking special care to removeany small glass fragments.

After removing all traces of glue andglass from the frame, clean theadhesion areas with 90% (or higher)isopropyl alcohol and a lint-free clothor coffee filter. Swipe in onedirection only, not back and forth.

If the frame is bent, or if any glue orglass remnants are left behind, thenew display will not mount correctlyand may be damaged. If necessary,replace the frame.

The best way to secure the newscreen is with a sheet of custom-cutdouble-sided tape. Apply the tape tothe back of the screen, thencarefully feed the display cablethrough the frame. Align the screenand press it into place.
