Introduction

With this detailed step-by-step guide, you can easily replace your Galaxy Note 9 display at home.

A replacement is necessary when the glass is shattered, the touchscreen does not respond to touch anymore, or the display remains black or flickers. During this repair, we replace the entire display unit including the frame, not just the broken screen. You may have to take some small parts from the old display unit, depending on how the new spare part is equipped.

The repair is a bit difficult as the Galaxy Note 9 has to be opened via the glass backcover. Removing the back cover is a somewhat more diffucult procedure, so plan enough time for it.

Do a backup before the repair, use a clean work surface and reserve enough time. If you are stuck at any point, just contact our live chat or write a comment on the corresponding step.

Getting started

32 steps
  1. Switching off your device

    Galaxy Note 9 - Switching off your device 01
    Galaxy Note 9 - Switching off your device 02
    Galaxy Note 9 - Switching off your device 03
    1. Turn off your device by holding down the power button until the “Power off” option appears.
    2. Use your finger to confirm that you want to shut down your Galaxy Note 9 and wait until the screen goes blank.
  2. Removing the back cover

    Galaxy Note 9 - Removing the back cover 06
    1. The back cover’s really glued to the chassis. Heat the device evenly with hot air to soften the glue. A temperature of 60 - 80°C should be sufficient. As a rule of thumb, you should still be able to touch your device without it being uncomfortably hot.
    2. The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex. You will also need several picks to unstick the back cover all around.
    1. Heat the spot where you start and place a flat tool between the back cover and the frame.

    The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert.

    Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.

    1. Once the tool is inserted, stick a pick into the gap to keep it open. Then run the tool around the entire edge to gradually loosen the glue.
    2. Then heat the next part and insert the picks one by one.

    The back cover glue is extra strong on the lower edge.

    1. Once the back cover is loosened, lift it very slightly. The fingerprint sensor underneath the camera is still connected with a cable.

    Use a suction cup to lift the glass if you can’t find anywhere to insert the tool

  3. Disconnecting the fingerprint sensor

    1. After detaching the back cover, carefully lift it and disconnect the fingerprint sensor using the spudger.
    2. Then you can completely remove the back cover and set it aside.
  4. Removing the NFC antenna

    • Battery connector
    1. Using the spudger, carefully disconnect the battery contact from the motherboard.

    Always lever from a side where there are no small components on the motherboard. This avoids unintentional damage to capacitors or ICs.

  6. Removing the battery

    Galaxy Note 9 - Removing the battery 06

    The battery glue is very strong, so you should use hot air again. The battery is glued around the outer edges but not at the center.

    Never heat the battery directly and don't bend it.

    Watch the video (playbutton in the upper right corner of the first picture) to see the release of the battery.

    1. Apply the hot air from the display side.
    2. We recommend running a flat tool, such as the iFlex, all around the battery.
    3. If the iPlastix is not strong enough, you can also use a wide battery spudger.
    4. Slide a flat tool under the battery to gradually loosen the adhesive. Do not push the tool too far in, otherwise you could damage the display from below.
    5. Lift up the battery and remove it from the device.
    Be careful not to damage the battery. Take your time and heat the glue several times.
