Follow this guide to replace the back cover of your Samsung Galaxy Note9.

  1. Samsung Galaxy Note9 Back Cover Replacement, Apply a heated iOpener: stap 1, afbeelding 1 van 1
    • Power off your phone before beginning disassembly.

    • Use a hairdryer, a heatgun, or prepare an iOpener and apply it to the right edge of the back of the phone for about a minute to soften the adhesive underneath.

    If using an iOpener it will need to be fully heated and set on for at least 5 minutes. You’ll know the phone is hot enough when its almost too hot to touch.

    • Apply a suction handle to the back cover.

    • Lift with a suction handle to create a gap between the back cover and the frame of the phone.

    • Insert an opening pick into the gap.

    • If the glass is badly cracked, cover it in packing tape to create a surface for the suction cup to adhere to.

    • If the adhesive won't budge, apply more heat, not excessive force. Too much force could break the glass.

    • Note that there is more adhesive along the top edge and around the camera bezel than around the rest of the phone.

    • Cut carefully around the left edge near the fingerprint sensor or you risk damaging the ribbon cable inside.

  4. Samsung Galaxy Note9 Back Cover Replacement, Slide the opening pick: stap 4, afbeelding 1 van 3 Samsung Galaxy Note9 Back Cover Replacement, Slide the opening pick: stap 4, afbeelding 2 van 3 Samsung Galaxy Note9 Back Cover Replacement, Slide the opening pick: stap 4, afbeelding 3 van 3
    • Starting from the center, cut the adhesive up and down the right side with an opening pick.

    • Do not insert the pick more than halfway into the phone when cutting near the fingerprint sensor or cameras, or you risk damaging internal components.

    • Leave an opening pick in the upper-right corner.

    • Use another opening pick to cut the adhesive around the bottom-right corner.

    • Leave that opening pick in the phone.

    • Use an iOpener, hair dryer, or heat gun to apply more heat as needed where you are cutting the adhesive.

    • Use a heat gun or hair dryer or apply a heated iOpener to the left side of the rear panel for about a minute to soften the adhesive underneath.

    If using an iOpener it will need to be fully heated and set on for at least 5 minutes. You’ll know the phone is hot enough when its almost too hot to touch.

    • Insert an opening pick into the lower-left corner of the rear panel.

    • Using another opening pick, cut the adhesive along the left edge of the rear panel.

    • Do not insert an opening pick in more than half way on the left edge near the fingerprint sensor or you may damage the ribbon cable inside.

    • It is fine if opening picks fall out as the back cover becomes separated.

    • Using the inserted opening pick, carefully cut the adhesive around the upper-left corner of the rear panel.

    • Finally, cut the last of the adhesive along the top of the phone.

    • Use an iOpener, hair dryer, or heat gun to apply more heat as needed where you are cutting the adhesive.

    • Separate the right side of the rear cover first.

    • Tilt the cover up along the left edge to expose the fingerprint sensor ribbon cable.

    • Do not pull out the fingerprint sensor ribbon cable yet.

  10. Samsung Galaxy Note9 Back Cover Replacement, Disconnect the fingerprint sensor: stap 10, afbeelding 1 van 2 Samsung Galaxy Note9 Back Cover Replacement, Disconnect the fingerprint sensor: stap 10, afbeelding 2 van 2
    • Use the tip of a spudger to pry the fingerprint sensor ribbon cable up and out of its socket.

  11. Samsung Galaxy Note9 Back Cover Replacement: stap 11, afbeelding 1 van 1
    • Remove the back cover.

    • To install a back cover:

    • Use tweezers to peel away any remaining adhesive from the phone's chassis. Then clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to prep the surface for the new adhesive.

    • Turn on your phone and test your repair before installing new adhesive and resealing the phone.

    • Carefully apply the new adhesive to the back cover, then line up one edge of the glass against the phone chassis and firmly press the glass into the phone.

    • Alternatively, you may reinstall the back cover without replacing the adhesive. Remove any large chunks of adhesive that might prevent the back cover from sitting down flush. After installation, heat the back cover and apply pressure to secure it. It won't be waterproof, but the glue is usually more than strong enough to hold.

    I am installing a new backplate (this is my first repair; I was CERTAIN that I would crack the back glass, and I was NOT wrong) but I’m not sure how tweezers are meant to remove gooey adhesive! I simply used the blue plastic pry tool as a scraper and gently rolled up the goo. Maybe the glue is different because I have a refurbished phone? That may also explain why I had so much trouble with Step 1. Hope that this helps!

    • Use a heat gun or hair dryer or apply a heated iOpener on the outside of the fingerprint sensor to soften the adhesive underneath.

    • Remove the fingerprint sensor.

    • To instal a fingerprint sensor:

    • Use tweezers to peel off as much adhesive as you can. Then clean off the remaining adhesive with 90% isopropyl alcohol and a lint-free cloth.

    • To re-install an existing fingerprint sensor, use a pre-cut adhesive sheet to replace the original adhesive.

    The fingerprint sensor I had was much to tight to connect it before the rear glass. After experimenting with the finest tweezers, trying to secure the connector was not possible. Instead I removed the sensor from the glass, secured the connector to the port then lowered the glass over the sensor. Because the sensor body is closer to midline I had enough clearance to make fine adjustments with a pin in order to align it with the rear glass cutout. Other than reversing those steps the rest of this guide was excellent. Good work and successful repair.

Conclusie

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

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

Repair didn’t go as planned? Check out our Answers community for troubleshooting help.

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.
