Samsung Galaxy S9 Plus Display Replacement

Introduction

Use this guide to replace a cracked or broken display on your Samsung Galaxy S9 Plus.

Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

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 display does not come with adhesive, use a strong double-sided tape such as Tesa 61395 to secure it.

Opening the Samsung Galaxy S9 Plus will damage the waterproof seals on the device. If you do not replace the adhesive seals, your phone will function normally, but will lose its water protection.

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.

What you need

Video Overview

  1. Samsung Galaxy S9 Plus Display Replacement, Rear Glass Removal: step 1, image 1 of 1

    • Switch off your phone.

    • Use an iOpener to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes. You might want to repeat this step several times during the back cover removal.

    • The adhesive of the Samsung Galaxy S9 Plus is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

    • In the following steps, you'll be cutting through the adhesive securing the back cover.

    • The adhesive in the inside of the back cover is laid out as seen in the image.

    • You'll be slicing through the adhesive in the areas shown:

    • Thick portions of adhesive

    • Thin areas of adhesive

    • Avoid prying or slicing in this area, to protect the fingerprint sensor flex cable.

    • If the phone's rear glass 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.

    • Press a suction cup onto the back cover.

    • Lift the back cover's bottom edge with your suction cup, opening a slight gap between the back cover and the frame.

    • This may require a significant amount of force, but you only need to open a very slight gap with the suction cup to insert your tool. If you have trouble, apply more heat to further soften the adhesive, and try again. The adhesive cools very fast, so you may need to heat it repeatedly.

    • Insert an opening pick in the gap and slide it to the bottom right corner.

    • Insert a second opening pick and slide it to the bottom left corner.

    • Insert a third opening pick at the bottom end of the phone. This opening pick stays there during the rear glass removal procedure to prevent the adhesive from resealing.

    • Start to slide the tip of the opening pick from the bottom left corner along the side of the S9 Plus.

    • Leave the opening pick in its place after you cut the adhesive half way up the left side of the phone.

    • Slide the opening pick from the bottom right corner half way up the frame and leave it there.

    • Insert a fourth opening pick at the right side of the frame and slide it to the top right corner.

    • Slide a fifth opening pick along the left side of the phone to the top left corner.

    • Use the opening pick to cut the remaining adhesive under the upper part of the rear glass.

    • Don't open the phone all the way yet. The flex cable for the fingerprint reader is still connected to the motherboard.

    • Prepare an iOpener and apply it to the display for at least two minutes to loosen the adhesive beneath.

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

    • If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.

    • Lay overlapping strips of clear packing tape over the display until the whole face is covered.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

    • Once you cut the adhesive on all sides of the phone you can slowly lift the display upwards and remove it.

    • The display cable is threaded through a hole in the midframe; guide it through carefully in order to free the display.

    • Before installing a new display, it's very important to remove all traces of the old adhesive from the frame, and clean the glued areas with isopropyl alcohol (>90%) and a lint-free cloth.

    • 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.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

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.

To reassemble your device, follow the above steps in reverse order.

After you've completed the repair, follow this guide to test your repair.

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.

Take your e-waste to an R2 or e-Stewards certified recycler.
