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—transplanting your phone's internals and installing a new battery. Make sure you have the correct part before starting this guide.

This guide involves removing the rear glass cover, you will need replacement adhesive to reattach the back cover to the phone. If your replacement screen does not come with adhesive, you will need to 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 mount correctly and can suffer damage from uneven pressure.

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

Schritt 1 Screen  ¶ 

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

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

Schritt 2  ¶ 

Heat an iOpener and apply it to one of the long edges of the S8 for about 2 minutes.

Schritt 2  ¶ 

  • Heat an iOpener and apply it to one of the long edges of the S8 for about 2 minutes.

  • You may need to reheat and reapply the iOpener several times to get the phone warm enough. Follow the iOpener instructions to avoid overheating.

Schritt 3  ¶ 

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

Schritt 3  ¶ 

  • Once the screen is warm to the touch, apply a suction cup as close to the heated edge of the phone 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 screen 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 display assembly.

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

Schritt 4  ¶ 

Once you have the tool firmly inserted into the glass, reheat and reapply the iOpener to soften the adhesive.

Schritt 5  ¶ 

Slide an opening pick or the blade of a Halberd spudger down the side of the phone, separating the adhesive. Go slowly so that the tool doesn't slip out of the seam. If cutting becomes too difficult, reheat and reapply the iOpener.

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

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

Schritt 6  ¶ 

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 from resealing. When inserting the opening picks into the side of the phone, insert a long edge of the opening pick, 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-facing sensors and earpiece speaker.

Schritt 7  ¶ 

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 digitizer connector. Pry on the opposite side of the phone from the connector—the connector will act as a hinge.

  • Follow this link for a detailed screen adhesive application guide.

  • Before installing a new display, it's very important to remove all traces of the old adhesive from the frame, while taking special care to remove any small glass fragments.

  • After removing all traces of glue and glass from the frame, clean the adhesion areas with 90% (or higher) isopropyl alcohol and a lint-free cloth or coffee filter. Swipe in one direction only, not back and forth.

  • If the frame is bent, or if any glue or glass remnants are left behind, the new display will not mount correctly and may be damaged. If necessary, replace the frame.

  • The best way to secure the new screen is with a sheet of custom-cut double-sided tape. Apply the tape to the back of the screen, then carefully feed the display cable through the frame. Align the screen and press it into place.
