Samsung Galaxy S7 Edge Display Assembly Replacement

Insert a SIM eject bit, SIM card opening tool, or a paperclip into the small hole on the top edge of the phone, located within the long rectangular cutout.

Make sure to insert it into the correct hole — pressing in an incorrect location can cause damage.

• Press in the opening tool to eject the tray.
• Remove the SIM/SD card combo tray from the phone.

Waterproof seals will be compromised when opening your phone; prepare replacement adhesive beforehand to prevent water exposure during reassembly.

• Apply an iOpener to a long edge of the phone for about two minutes to loosen the adhesive.
• Reheat and reapply as needed, but follow the iOpener's instructions to avoid overheating.

When using alternative heat sources (e.g. hair dryer, heat gun, hot plate), be cautious not to overheat the OLED display or internal battery, which are prone to heat damage.

Apply caution when handling hot components.

• Warm the back panel until it's warm to the touch.
• Attach a suction cup near the heated edge, avoiding the curved section.
• Apply strong tape or superglue if back cover is cracked for better adhesion.

Lift the suction cup and carefully insert an opening pick under the rear glass.

Due to the curved design, apply pressure perpendicular to the phone's surface.

Reapply heat as needed to soften the adhesive, which cools quickly.

Reheat and reapply iOpener to soften the adhesive.

• Make sure your pick is still firmly in place within the glass.

Slide the opening pick along the side of the phone, separating the adhesive.

• Go slowly to avoid the tip slipping out of the seam.
• If sliding becomes difficult, reheat and reapply the iOpener.
• Leave the pick in place and grab a second pick for the next step to prevent re-adhesion.

Continue heating and cutting the adhesive around the remaining three sides of the device, leaving an opening pick in place on each side before moving to the next.

• Apply heat to the next side using a heat gun.
• Insert an opening pick under the edge of the phone and gently pry up.
• Continue this process for each remaining side, repeating steps 1-2.

Remove the glass cover by carefully lifting it off the phone.

• Lift the glass upwards to disengage it from the phone casing.
• Gently pull the glass away from the phone and set it aside.

Use tweezers to remove remaining adhesive from the phone's 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 onto the phone.
• If reinstalling old back cover or using non-adhesive back cover, follow this guide.

Do not install new adhesive without testing your repair first.

• Remove large chunks of existing adhesive to ensure proper fit.
• Apply heat and pressure to secure the back cover (note: phone will not be waterproof).

Remove the 12 x 3.5mm Phillips screws.

Locate the small notch at the lower left of the upper antenna.

Pry the upper antenna out using this notch.

• Remove the upper antenna.

Remove the wireless charging coil by lifting it out of the phone.

Remove the loudspeaker by lifting it out of the phone.

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

Disconnect the display cable using the flat end of a spudger.

Disconnect the power button cable by inserting the pointed end of a spudger.

Disconnect the red and white antenna cables with the pointed end of a spudger.

Disconnect the home button connector using the flat end of a spudger.

Disconnect the front-facing sensory array cables using the pointed end of a spudger.

Disconnect the volume button cable using the pointed end of a spudger.

Do not lift the motherboard fully — it remains connected via a cable.

• Use the flat end of a spudger to gently pry the motherboard upwards.
• Grip the edges and hinge the motherboard up slowly, using the spudger to clear cables as needed.

• Disconnect the daughterboard ribbon cable using the flat end of a spudger.
• Remove the motherboard.

Apply iOpener to top edge of display and wait for it to become warm.

• Be careful not to overheat, as this can cause damage to the OLED display and internal battery.

• Reapply heat as needed until the adhesive softens.

Alternative heating methods include using a hair dryer, heat gun, or hot plate. However, be cautious not to overexpose the phone to heat.

While waiting for the adhesive to soften, proceed to the next step and read through it carefully to plan your prying points.

The capacitive buttons and ribbon cables are fragile and require extra caution.

• Remove the strong double-sided tape from the copper surface.
• Be careful not to damage the capacitive buttons, which must be reused for this repair.
• Gently pry the display assembly edges away from the foam adhesive strips.
• Take extreme care when handling the ribbon cables to avoid breakage.

If either of the capacitive buttons or ribbon cables are damaged, you can replace the daughterboard assembly with new parts.

Apply a suction cup near the top edge of the display, avoiding overlap with the speaker grill.

• If your display is severely cracked, apply strong tape to help lift it.
• Lift the display on the suction cup to create a small gap at the top edge.

Be prepared for significant force and repeat the heat-suction-lift procedure as needed.

• Insert an opening pick into the gap, limiting insertion depth to 0.25 inches.
• Expect multiple attempts due to strong adhesive; follow iOpener heating instructions and repeat the process until a pick is in place.

Apply a heated iOpener to the top edge for 2 minutes.

• This will help loosen the remaining adhesive.
• Proceed with caution, as the adhesive may still be sticky.

Slide a opening pick along the top edge of the display, avoiding depths over 0.25 inches.

Inserting the pick too far may damage the front-facing camera or earpiece speaker.

• Leave the pick in place to prevent adhesive resealing.

Repeat heating and cutting procedure for long phone edges.

• Do not cut bottom edge yet.
• Work slowly to slice through adhesive holding display to frame.
• Leave opening pick on each edge as you continue to prevent resealing.

Be cautious of the display cable located above the right side midpoint, which may interfere with your pick if prying too deeply.

Insert an opening pick into the bottom right corner of the device.

• Push the pick slowly into position.
• Leverage the cutting edge upward so that it slides against the back of the display.

This technique helps prevent damage to the capacitive button's cable.

Once the adhesive is cut, leave the pick in place to avoid resealing.

Insert an opening pick into the bottom left corner.

• Push the pick slowly into place.
• Leverage the cutting edge upward against the display back.
• Once adhesive is cut, leave the pick in place to prevent resealing.

Be careful not to damage the display cable when prying open the phone.

• Use the opening picks to slice through adhesive around the home button and remaining adhesive.
• Open the phone slightly, starting at the edge opposite the display cable.
• The display assembly remains attached; there is a connected display cable running through the midframe.

Carefully lift the display assembly away from the midframe.

• Thread the display cable through the corresponding hole.
• Once clear, remove the entire display assembly.

Adhesive residue on the frame can cause installation issues.

• Remove old adhesive from the frame using a plastic scraper or credit card.
• Clean adhesion areas with 90% isopropyl alcohol and a lint-free cloth or coffee filter, swiping in one direction only.

A bent frame or remaining glue/glass fragments can damage the new display.

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